    I posted this once but never got any responses, so here it goes again.

    For those of you who are making both the statements and the mini statements, are you using the mini statements as surround speakers in HT applications?

    I have been considering going this route for my new HT room but am wondering if this would be overkill??????

    Lastly, if i did go this route, I would need to build them on about a 1-2 foot pedestel to get them up above my raised seating. Are the minis ported out the bottom or the back?

    Thanks everyone,

    Dr Trina
    I have the Statements in the front and Minis as my surrounds and it is an unbelievable setup. I like 5-channel music and with this setup there is no need for a sub. I do not look at it as overkill (my wife might...).

    I don't watch much in the way of movies so I am not a very good barometer for that. The movies I have watched through this setup have been awesome as well, though.

    I would say just build them and see. If you feel it is overkill use the Minis in another room as mains. While I was finishing the Statements I had the Minis hooked up as mains with Modula MTs in the back. This was very nice as well. HTH! :T

      I'll start a Center build thread when we officially announce the design.

        Thanks for the info. A little taller then I was hoping for. The shelf on my TV stand is 9 inches tall, but it may be worth modifying my TV stand for it.

        Thanks,
        Topp

          Hi Topp,

          Unfortunately, the W4 and the ribbon have a combined height of 9 1/3" without any cabinet. 11" is a fairly snug fit.

          I think the center is going to be a real winner based on the sound quality and clarity of the Statements. I'll soon know.

          Jim

            My sealed variant has been fired up. Sounds very nice compared to our older HTIB set. Suspect more power to drive will liven them up...Reciever only handles 100W at 8Ohms, ...so we don't go too crazy with them. Older Onkyo don't have a 4Ohm spec, but according to them should be ok unless its cranked. Hard to really say without a reference for what "good,accurate" sound sounds like...We do notice much more clarity. Even have the OK for the center!.
            One question that arose soldering in the drivers, what are the +/- terminals on the tweeter? Neither are marked, just one red lug and 1 blue.
            Have the 5.2mm MDF backed walnut veneer already, but they didn't have any 4/4 Black Walnut lumber we liked for the trim to cover the veneer edges.
            They will match the cabinet look when we are done. (Made that too) Thats why the questions on flipping the full size to get the tweet at the right height and adding 1.5-2inch to the baffle width.


            Pictures show their home once they are all dressed up, and what they are replacing.

              Hi Dave,

              I'm glad to hear you have your Statements up and running. I'm not surprised they sound much different than the HIB that they're replacing. The highs should sparkle, the mid range should be extremely smooth and detailed and the bass should be extremely tight an accurate down to the bottom octave. Below that sealed, you do need a sub woofer.

              The better your source equipment, the better they sound. We're looking forward to seeing pictures once they're completed.

              I picked up the center today from Curt and it sounds superb! We'll have all of the details available very soon.

              Enjoy!

              Jim

                What about the tweeter? What are the +/- terminals? I assumed that red = +, blue = -.

                  Yeah, red is usually positive unless it's an Eton ER4. In this case, for the Fountek, red is positive.

                    I'm finishing the build of the cabinets and need to make a decision on the method to damp the inside of the cabinets. Considering what this design offers, I'm interested in a quick discussion of the difference in damping needs. As the mids are in their own enclosure, the main cabinet really needs to addess the damping from the low pass on the RS225 down. It appears that this may significantly impact the choice of damping material.

                    In addition, I have designed my cabinets so that the reflection of any wave that is not attenuated by the material would be released in a direction such that it will pass through another layer of the material on an adjacent wall before getting back to the cone on the driver.

                    The options I am considering include:
                    - Open-Cell Egg Crate (bed foam), used on other projects, on hand.
                    - OC Fiberglass, un-faced, used for home projects, on hand.
                    - Foambymail.com 2" acoustic foam, used by Jim, I've heard speakers using this and have been impressed, not on hand.

                    Fiberglass:
                    Owens Corning Fiberglass Batts (fluffy pink)
                    Product thickness mounting 125hz 250hz 500hz 1000hz 2000hz 4000hz NRC
                    Unfaced 3.5" R11 on wall 0.34 0.85 1.09 0.97 0.97 1.12 0.95
                    Unfaced 6.25" R19 on wall 0.64 1.14 1.09 0.99 1.00 1.21 1.05

                    Foambymail.com:
                    Product thickness mounting 125hz 250hz 500hz 1000hz 2000hz 4000hz NRC
                    Wedge 2" Foam on wall 0.13 0.29 0.89 1.08 0.97 1.04 0.81

                    (I've added this information as a table attachment as the text is misaligned)

                    I don't have the detail on the egg crate (bed foam), but based on reviews and members remarks (as well as Zaph's sentiments), I'll assume that either of the above are likely to be better. While the 2" Wedge foam appears to be better in the upper midrange, the fiberglass seems to be much better in the lower mid and upper base where the RS225s are operating.

                    So is this a rather clear nod to the fiberglass for the main cabinet's on the Statements? ....or is there something I am overlooking?

                      Jim,
                      Spent some time listening to the sealed on Sunday, running around doing our usual housework. Listening to various CD's, we noticed that at the same apparent volume, we had to speak MUCH louder to hear each other. It also filled the bulk of the house very clearly compared to the old HTIB pair. It's hard to describe, they seem much more enveloping. I guess that would be described as presence/soundstage? Needless to say wife likes them, and thats always a plus.

                        Center Crossover

                        Jim and Curt,

                        I hope the weekend went well with the center crossover. When it is posted, will the crossover parts and schematics be posted on this thread or on a separate center thread?

                          Hi Doc,

                          There will be a separate center channel build thread that will coincide with Curt publishing the center web page.

                          Jim

                            Statement Pics

                            Hello,

                            I got a chance to clean up the speakers. Since they were painted like a car, I actually used turtle wax!

                            I love the high gloss finish, however, since they reflect pretty much everything, it is almost impossible to get a good picture of them.

                            Here I have included a front and side profile shot.

                            I also included pictures of the grills I made for the back mid pass through and the front of the speakers.

                            If you're wondering what is below the bottom woofer, that is my little special touch. My initials ar TT, so I got some Audi TT decals from the dealership to make these statements MINE.

                            Lastly, as Jim can attest, the crossover terrified me. Because of this, I decided to build an "escape hatch." I included the picture of the removable back panel.

                            Many thanks to Jim and Curt. I think Jim must have gotten at least daily emails from me for about 2 months.

                            What a great first experience!!!!!

                            I hope you like them,
                            Dr Trina

                              Hi Doc,

                              They look great and I know how good they sound. :T

                              I have the same problem taking pictures of gloss black speakers. Everything reflects.

                              Thanks for the kind words and thanks for sharing photos of the finished Statements! I know how hard you worked on them. Great job!

                                Doc,

                                You chose a great project for your first one! Those look absolutely stunning. I can only imagine how much better they actually look in the flesh!

                                You were pretty kind to Jim only emailing him daily. I think I emailed him twice to three times an hour for the duration of my build. I am guessing Jim was about ready to fly down to Florida and finish the darn things for me so I would quit pestering him! Thing about that though, Jim ALWAYS answered every email in a very timely manner, with nothing but words of encouragement and always an offer to help in any way possible. He never accepts any credit for all of the help he provided, but I will guarantee this project would have never turned out as good as it did for me had it not been for Jim! ;x(

                                Anyway, enjoy your speakers, I know I certainly have, and have a great day. :T

                                  Another pair of Statements were completed a few minutes ago and are playing for the first time. I'm not going to offer any comments about the sound after less than 30 minutes of breakin time other than to say they sound very good in my system. Mine are ported through the back panel, and the base is 5" high because I don't use spikes on the hardwood floor. The mid and tweeter crossovers are housed in the base.

                                  Not sure how to post pictures, but you can see them in all their naked mdf glory here: http://fredt300b.smugmug.com/gallery/132721#203602416

                                    Hi Fred,

                                    Welcome to the HT Guide Statements thread. The pictures look great and I'm really interested in hearing your thoughts once you've had a chance to spend some time listening to them. I know you have good front end equipment. When you post, could you give us an idea of what the rest of your system consists of?

                                    BTW, the actual crossover points are 350 and 3700.

                                    Thanks for posting! :T

                                    Jim

                                        Haven't decided yet, but I'm thinking about cherry veneer. It's too soon to comment extensively about the sound, but have you noticed some speakers are easy to listen to, and these are among the easiest. The bass is full and rich but tightly controlled, the soundstage is large but you cans still pinpoint the position of that female vocalist, and the treble is crystal clear with no hint of that etched quality I hear from some other very expensive mainstream speakers. :T

                                        Jim had asked about the other equipment in the system. The CD player is an Arcam FMJ, the preamp is a little-known Assemblage (Sonic Frontiers kit division) hybrid tube/fet with extensive upgrades in the power supply and signal path, and the amps are zero feedback class A Monarchy SM-70 Pro's.

                                        And now for a crossover question: What is the purpose of the RC bypass around the midrange inductor? Is 0.47uF the correct value for that cap?

                                          Good morning Fred!

                                          Well, it sounds like you're off to a good start with the Statements. I'm glad you're enjoying them. If you get a chance, pop in some of the recordings that made you go "WOW" when you first got your line arrays and listen to them on the Statements. The Statements really like extremely well recorded complex music with lots of detail. :T

                                          Thanks for listing the front end equipment. The Statements also like very good electronics. My experience has been, the better the electronics, the better they sound. I don't think anyone has tried tubes yet but I suspect, it would be very nice.

                                          I sent Curt an email about your crossover question. He'll jump in with the answer. ;x( He's the brains. I just do the heavy lifting.

                                          Please keep us posted with your progress and further listening impressions. We like pictures!

                                            Hello Fred,

                                            Yes, 0.47 uF is the correct value. The full range response of the W41337 has a significant peak of about 10 db around 15K. Although I crossed the mid much lower, this peak would clearly still generate significant energy, and in my experience be quite audible. To mitigate that response peak I utilized a Cauer elliptical type filter topology. While L2021 is one of the main components of the low pass filter, it also functions with C2021 and R2022 to provide a notch filter around 15K. Certainly I could have used a more traditional separate conjugate filter, but this method results in a lower parts count, which all else being equal, is always a good thing.

                                            I'm glad to hear your initial listening impressions were favorable.

                                            C

                                              Thanks for the explanation. I couldn't imagine how a 0.47uF cap would effect the pass band of the midrange. That value makes sense now that I know it's there to help null a 15Khz peak. The Statements have been playing all day, and they're getting better by the hour.

                                              Jim mentioned nobody has reported on their sound with tubes. Sounds like a good test for my 50 watt Ella KT-88 amp. I want to let them break in for a while longer, but sometime soon I'll rewire the Ella for four ohms and give it a try. It worked well with the Eros MKII MTM's, whose impedance dips well below four ohms, so it should be a good match for the Statements too. I'm also building a 50 watt gainclone chip amp that should be an interesting match. Damn its nice to be retired and able to spend all day playing with audio toys.

                                              Oh, I almost forgot, I have to take them apart for a couple of weeks soon to veneer and finish them.

                                                I will also be interested on your valve findings. The impedance swings of the Statements are relatively benign, being between 4 and 10 ohms, so I'd expect only slight response aberrations due to the higher impedance of the output transformers. I speculate the combination of Statements and a well-matched tube amp may result in an excellent sonic collaboration.

                                                  Some tube amps, especially low power SET amps with zero negative feedback, aren't a good match for low impedance speakers. They unfairly give all tube amps a bad reputation, mostly because of their inability to control the bass.

                                                  Push-pull amps, especially those with some negative feedback, are better than SET's with low impedance speakers, and the impedance range of the Statements should be no problem for my 50 watt Ella KT-88 push pull amp. It works very well with the Eros MKII MTM's, whose impedance dips well below four ohms. It's presently wired for eight ohms, but I'll change it this weekend and give it a try. I'll post a message with my impressions.

                                                    Sealed Statements

                                                    Jim and Curt,

                                                    If you remember, while I was building my statements, I had accidentally placed the lower woofer 1" lower than the specs called for. At that point, you had said it would not affect anything, but being the type A person that I am, I sat those aside and re-made the front baffles from scratch.

                                                    Now, looking at how much time was put into it, I would like to take the original front baffles, cut them off a few inches below the bottom woofer, and turn them into a sealed statement that rivals the minis in size.

                                                    Does that sound like a plan that would work?
                                                    Would the volume be appropriate?
                                                    Would the crossover designed for the full size statements work?

                                                    Thanks a lot,
                                                    Dr Trina

                                                      If you remember, while I was building my statements, I had accidentally placed the lower woofer 1" lower than the specs called for. At that point, you had said it would not affect anything, but being the type A person that I am, I sat those aside and re-made the front baffles from scratch.

                                                      Now, looking at how much time was put into it, I would like to take the original front baffles, cut them off a few inches below the bottom woofer, and turn them into a sealed statement that rivals the minis in size.

                                                      Does that sound like a plan that would work?
                                                      Would the volume be appropriate?
                                                      Would the crossover designed for the full size statements work?

                                                      Thanks a lot,
                                                      Dr Trina
                                                      Hi Doc,

                                                      If you cut them 40" high with the same baffle width and cabinet depth you'll end up with a box alignment of around .65 which is excellent for sealed bass. The bass quantity and quality would be very similar to Ryan's RS 3-ways.

                                                      The problem is, you still have to get the ribbon at seated ear height so they'll have to sit them on something to raise them up high enough.

                                                      Crossover will not be affected. Check out That Dave's posts on 9/29 and 10/1 for sealed sound quality impressions. Really the only difference you'll notice is the bass doesn't go as deep in a sealed configuration. Mids and highs will be the same.

                                                      HTH

                                                        That sounds like it can be done. I will be either mounting it to the wall at the right height or building a custome height pedestal. In this application will they need to be so far off the wall liek the others or not?

                                                          Hi Doc,

                                                          The open back mid requirements don't change so no wall mounting. They should be at very minimum no closer than a foot from the back of the cabinet to the wall and 1 1/2' or more would be better. The mids have to have room to breathe out the back.

                                                          Jim

                                                            A few posts back, there were questions asked about the port length and the use of different port kits. Specifically, these questions asked about the length of the inner tube less the flared ends. After reviewing the PE kit directions, the responses, and taking a few measurements, I concluded that the Precision Port(tm) kit from PE is considerably different than some of the other port kits used.

                                                            For those using the 3” Diameter Precision PortTM Kit from Parts Express (268-350), I calculate the inner tube length to be 1.65 inches. With an overall port assembly length (with flares) of 7.65 inches. This is based on the following assumptions:

                                                            Vb = 3.74 ft^3 (estimated from Autocad Drawings)
                                                            Fb = 24 hz (from Curt’s website – noted approximate)
                                                            R = 1.5 in

                                                            The attachment steps you through the calculations.

                                                            I post this in case someone quickly overlooks the potential differences in port kits. PLEASE let me know if you see an error in my calcs.

                                                                I don't think anyone can really answer your question. I think Todd has the formula for the Precision ports worked out in the post above yours. I guess the real question is, how's the bass with the length you have now? If it sounds good, it's good to go. The different length would change the box tuning somewhat but how much I can't answer.

                                                                To any prospective builders reading this post, it's just easier to use PE's make a port kit. Very, very simple! :T

                                                                  If my quick math is right, you have simply changed the port tuning frequency from 24Hz to ~21Hz. You can check this by using the process I outline, setting Lv = 9inches (assuming you used a 4" inner tube length) and solve for Fb. As Jim mentioned, you'll have to decide if you really think you need to tear it apart.

                                                                    It sounds to me like Cocoanutout has a total length including flares of 5" (equivalent to a 4" straight port) which will raise the tuning to 29Hz or so. Maybe Jim and Curt can clarify exactly what they did and spell it out on the web page as the AutoCAD drawing is confusing and just says port = 4". I'm guessing they cut a 4" piece of straight pipe and slipped the PE flares on the ends which would probably give a total length similar to Todd's 7.65" (equivalent to 6.65" straight port).

The equipment (my system morphs from day to day) included my Squeezebox, a modded Lite Audio DAC-60, a highly modded tube preamp, and two very different amps over the course of the evening: first the Monarchy class A zero feedback amps bridged to run as 80 watt (140 into 4 ohms) monoblocks, then a 525w/ch (1KW into 4 ohms) class D Icepower stereo amp.

                                                                            One guest said the Statements had the best sound he has heard in my house. Another, Dennis Deacon, also made some very positive comments. Dennis has done design work for Wadia and other high end companies, and is now the "D" in D-Sonic amplifiers. Both preferred the Statements to the Selah Audio XT-8 line arrays that normally stand in the downstairs listening area, primarily because of the extended and powerful but well controlled bass and the very engaging midrange.

                                                                            Needless to say I'm very pleased with the Statements, but I'm always skeptical of my impressions of anything I've built myself. Most people who build speakers have a very strong positive bias regarding their own work. It's just human nature, and I'm no exception, so it was good to hear such positive remarks from other experienced and highly critical listeners. I've asked Dennis to join this forum and post some more specific comments about his impressions of the Statements, so we may be hearing from him. His amps are described at

                                                                              Anyone in dallas have built these?

                                                                                Thank you for the excellent review! :T

                                                                                The Statements have certainly changed my system since their construction. Like you, they started out to be another fun project that turned into a "Wow" experience. I'm very pleased that you and your guests enjoyed listening to the Statements as much as I and several other Statement owners do. We would also very much appreciate hearing Dennis remarks if he chooses to post them.


                                                                                ;x( Curt and Wayne deserve the credit for the Statements sound quality. Curt for his crossover wizardry and Wayne for the superb voicing assistance he brought to the project. BTW, the Mini's and matching center channel also have that same seductive midrange, sparkling highs and authoritative bass the Statements have, just a little less of it. More projects to build!

                                                                                Thank you again for the excellent review!

Strong, naturally dynamic soundstage with realistic note definition that gave a holographic quality to percussion of any type. Natural definition and impact of bass is captured down to the mid 30HZ level. On a wide variety of music could not notice any area of weakness. Sonic balance was seamless.

                                                                                    Other speakers I have listened to recently in this quality range cost from $4800 to $8000. The system designers for this project have provided an impressive value/dollar ratio.

                                                                                        You can see from my few pictures what the 40inch sealed look like in raw form. You can also see why the "normal" ones didn't quite fit. We can also later add the "missing" space/port if we move it to the floor later. They sound great...My wife is listening to music again as she tends the house, and loudly at that....maybe she will "hear" the Onkyo 703 driving them clip and demand an amp..
                                                                                        Waiting on my hardwood shop to get in another batch of walnut to finish mine off. Then off to the center.

                                                                                            Where did you put the crossover and how did you mount it to keep the inductors separate?

                                                                                            Lastly, if the wife likes them, it is time to start lobbying for more square footage dedicated to sound...good luck!
