  • Statement II - The Remix

    Some of the pictures no longer display because Photobucket discontinued their free picture hosting service. SORRY!

    Hey guys. It's been a while since I've been an active poster to the boards because I haven't been building many speakers in the past few years. That drought has come to an end. The past three builds I have done for myself have all be Jed’s Clearwave Dynamic 4T and 4CC, which I have thoroughly enjoyed. They have been PERFECT for my movie and music taste. However, since I am starting to listen to more music than watch movies, I thought I would try moving back to the Statement family and the version 2 that are geared more towards music. So while I wanted to build the Statement II’s, I knew I couldn't build them to spec as my wife HATED the size of the original Statements I built, which was the main factor in switching to the Dynamics. I've traded several emails with Curt and Jim over the past 16 months or so. During that time Jim informed me the non-shielded Dayton woofers require 30% less cabinet volume to perform at the same level as the discontinued shielded version. That’s when my mind started to work….

    I began designing a few cabinets, trying to shave off height from the cabinets. Knowing I needed to keep the midrange tunnels the same length and the tweeter at or near ear level (roughly 38-40 inches), the WMTMW driver layout wasn't allowing me to shave more than 4-5 inches off the overall height. A 54-56 inch tall cabinet would not be allowed back in the house while my wife still lived there. I traded a few more emails with Curt and Jim and we decided a MTMWW driver layout likely would not be a design buster. With the new driver layout and spacing complete, I began on a new set of cabinet designs. Overall cabinet height came in around 49-50 inches (depending on stand and speaker spikes) which is exactly the same as my current Dynamics. I was able to decrease the baffle width by an inch (per Curt’s approval). I preserved the overall cabinet depth and midrange tunnels length. Suddenly the cabinet design started to fall into place.

    Of course regular rectangular cabinets just would not do for this build. I always enjoy a speaker cabinet that looks as good as the speaker sounds. I began drawing a slight curve to the side panels, a flat rear panel, and a sloping top plate to help the visual height of the speaker. Nothing major with the curves, but something enough to be noticed and help the cabinet appear less massive. To help save some height with the base and port I moved the port to the backside of the cabinet. I made sure to keep the port below the lowest woofer. The final touch to a subtle cabinet curve... a detachable, curvy base with outrigger type feet. I've got some special plans for the binding posts as well. I haven’t had time to become a pro at Google Sketch-Up or any other CAD software, so you will all have to endure my lousy handmade drawings if you want a preview of the cabinets.


    Once the build is complete I will post my BOM for this build in case anyone wants to copy or draw inspiration. As luck would have it, I live 2 hours away from Jim and with his invitation I planning on taking my version of the Statements to his home to compare to the stock Statement II’s to my Statement II remix. It will be fun to see and hear any differences between the two builds.

    *I'd like to apologize in advance. I didn't take many pictures while I was creating the bracing, doing the rough cuts, or the fine trimming.

    Day 1 - Rough Cuts
    After finalizing the cabinet drawings, I began making saw dust. For the tower cabinets I determined I was able to get all the bracing and plates from one 4x8 sheet of 3/4” MDF, one 2x4 sheet of 3/4” plywood, one 2x4 sheet of 1/2” MDF, and a 4x4 sheet of ½” plywood.

    • 4x8 sheet of ¾” MDF - used for all the internal braces.
    • 2x4 sheet of ¾” plywood - used for templates for creating the internal braces.
    • 4x4 sheet of ½” plywood – used for bases.
    • 1/2” MDF was needed for the front baffle.

    I created a layout for the tower braces and cut it out of the ¾” plywood. I then traced that shape onto 16 precut MDF boards. Used a jig saw to rough cut the pieces and then the table router and my plywood template to make sure they are exactly the same. I bought the router table for this project and it has already aid for itself. The router table was a huge time saver compared to my past method of using the plunge router.

    I also cutout and created the base plates for the ½” plywood.

    Next I took 8 of the braces and trimmed them into tunnel braces and dado cut side tunnel joints. That was enough work in the cold for day 1.


    Day 2 – Create cabinet skeleton
    I finished creating the internal braces by cutting holes in the braces for free air movement. Normally I take great pride and make the braces look as close as possible to a CNC’ed part. But in the 6 years of doing this I have never once seen or thought about the internal bracing once the drivers are mounted. So this time, I spent very little time making sure everything ‘looked’ perfect. I constructed the midrange tunnel/braces and made sure to remove material for the tweeter knockout between the two tunnels. With the midrange tunnels complete, I cut supports using 1x2 poplar boards. These supports will help construct a skeleton of the cabinet using the braces. The skeleton will then be wrapped with side panels and completely enclosed with a front baffle.

        Thanks Jim. I'm actually a little further along that these posts and pictures show, but I am too busy building instead of posting.

          The weather is amazing. I have a project in the basement but I'm outside getting things done that I didn't plan on doing until the end of April. The weather is outstanding for March. I know it won't last but I'm enjoying it while its here.

            Looking forward to following this post. I built the Statement II as per original plan. I haven't taken any measurements yet but it'd be interesting to see what the non-shielded woofers do to the low end response.

            They are very handsome IMHO, but my wife also thinks they are very big. Luckily we have 12' ceilings so they don't look THAT big, but still. If you can shave off 25% of cabinet volume for little to no impact, or 1" off the width, it's probably a good move.

            These days they call speakers with 5.25" drivers "subwoofers" :roll:

            Did you have to modify the crossover to deal with the difference in response for the WWMTM (eg. floorbounce)

              No changes are being made to the crossovers. I am sure there will be some measurable differences with the smaller cabinet and different driver lineup, but I am not sure how audible it will be to my ears. I like to think I have fairly good hearing, but I've seen differences measured with a mic that my ears can't pick up. So if measurable differences are the only impact, I don't mind if I can have more manageable cabinet sizes.

                Made some more progress last night but forgot to snap some photos. I have the bases rough cut and trimmed to exact size. I also began building the skeleton of the cabinet after rounding over all the internal bracing. I was only able to build about half of each skeleton because of the number of clamps I own. It’s funny, I always think I own too many clamps, until I start building speakers. Then I think I need to double my quantity.

                I also began wiring the crossovers last night. It never fails, I always think wiring a crossover is no big deal and I choose not to pay for assembled crossovers. Then I begin trying to figure out layout and start messing around with the soldering iron and make a mistake. Then $90 for assembled crossovers seems like a bargain. But, mistakes were corrected and the woofer and tweeter circuits are complete. Tonight I should be able to complete the two midrange circuits. Each crossover is mounted on it’s own plywood board. The components are attached to the plywood using hot glue and/or zip ties for the heavier pieces.

                I will try to snap some photos of my progress after I complete work tonight.

                  Cant wait to see more progress and hear your impressions! I've got a set of statement IIs on my horizons, and love to know all my options! (and see good inspirational work I can shamelessly copy ops

                    soundemon - Shamelessly copy anything you like. That's the whole purpose of this thread and site.

                    A quick photo update. I didn't have much time to work on the speakers yesterday so not much was completed. I continued to build the cabinet skeleton and drilled the pilot holes which will house the t-nuts allowing for the base to attached/detach to the bottom framework of the cabinet. Here is the sole picture that was taken at the beginning of yesterdays work shop. You can see the midrange tunnel braces as well as the supports for the curved top plate.

                        Darren, it looks like you're well under way. I wish I could be building with you but as we talked about your plans seems to be all that I could hope for in a shorter curved cabinet design. The Statements are too tall and boxy for me as well.

                        You have the skills my man...I sure wish you could build mine....but that's the whole point of DIY I guess. I'm even thinking about a two-piece design like my Polk RT3000P's....we will see. I'll have to wait and see how it all turns out.

                        Anyway, I think you are off to a great start and on to something special with this design. Keep posting! And you guys are 4 hrs away....would be cool to be a part of the comparisons session.

                          Thanks Walt. I love building cabinets.

                          Some updates from today. I was able to install the brad nuts, or t-nuts, or whatever you want to call them. They allow the tower of the cabinet to be detached or secured to base.


                          I also finished building the cabinets. It's funny, after I had everything put together I thought, "Oh no... I forgot something. These aren't tall enough to be Statements." But after measuring them, they are a perfect 50 inches tall. Just as I had hoped. Here is a pic of the last of the braces and clamps coming off.


                          And just before my wife told me I needed to take her out to dinner, I was able to kerf cut the top plate and make sure I can get the curved top.


                          Tonight I hope to finish wiring up the crossovers. Tomorrow I hope to get the work more on the bases. I have some routing and internal wiring to do after I get the binding posts installed.

                            I made a lot of progress this weekend, although it is not easily seen in the pictures. One of the things I was dreading the took up a good amount of time, but it's complete; cutting the side curves on the top plate as it bends from front to back. With a fair amount of time, measuring, drawing it out, measuring again, creating test cuts, measuring again, and then crossing my fingers and making the final cut, everything lines up nearly perfect.


                            The front baffles were also routed this weekend. As I stated above, the midrange and tweeter spacing was kept exactly the same as the original Statements. I didn't snap of photo of the backside but the woofer and midrange holes do have a beveled ring to prevent tunneling of waves from the cones. Here's a picture of the front baffles leaning up against the cabinet skeletons.


                            I am hoping over the next week or so I can begin installing the 4-5 layers of 5mm plywood. The unusually warm temps for March here in Iowa are predicted to end after today (although it's supposed to be 80 today!!). While it's not freezing outside, I don't like to glue if the temperature isn't above 50 degrees. The forecast is projecting temps in the mid to upper 50's so I should be ok, but if the temps drop any more I will have to suspend construction until the temperatures get warmer.

                              Wow these look great, great job.

                              My wife said no way to the original height Statements as well, but these are a definite possiblility. I assume the Statement II center should match up with these as well (since the drivers/crossover are the same)? Maybe when you and Jim have your comparo you can find that out too.
