New Project, Peerless + VIfa

[gmed]

New Project using Peerless HDS 6.5 + Vifa D27TG-45-06
18 Liter enclosure, tilted at 10 degrees. I used Tony Gee's Cup-o-soup as an inspiration.
So far so good
for the main enclosure, Ill be using IKEA Lagan countertop

[JonMarsh]

Interesting and nice looking work- keep those pictures and progress reports coming! :W

[gmed]

Thank you Jon, Thanks to you, this project is looking great so far. Your pictures helped me a lot.

That's one hell of a jig! 8O Thanks for making me feel so inadequate with my woodworking skills. ;x(

[soundemon]

I'll be following this one with great interest! I love that profile for speakers and the itch to make a new pair of speakers is starting to build...

[gmed]

should get some work done this weekend
once i finish this baffle, ill get started on the second, then the enclosures
stay put

[nk215]

Love your skill and creativity. if it were me, I would just get a radial arm saw for the corner cuts. there's no way I can make a jig like that.

[SpeakerGuy]

Are you using the 830875?

[LING GOWA]

Looking real good so far.

[gmed]

So this weekend I accomplished a lot. The baffle is so thick, I actually had to cut from both sides. Why I pick such difficult designs, is beyond me!

Except for a minor error, everything is going well. Next week, Ill start working on the actual box which should be much easier. The baffle was hell! '

I have promised myself, after this set, Im retiring.

I still have some work on the baffle. Since I had to cut the holes from the back side as well, I have to even them out with a flush bit, then Ill chamfer the woofer hole.

As you can see in the second picture, I had a small accident. I over shot with the router, going beyond the truncated part, but i filled it with woof epoxy, so Im forced to stain it now so that it isnt visible. I know its there so its bugging the heck out of me. Im thinking of staining it graphite color, so we'll see.

[evilskillit]

Man those look nice. I'm curious, to alleviate the crazy thick baffle problem could you have just cut a square or oval shaped hole in some of the pieces below the first or second before gluing them so that the router work wouldn't need to go so deep? Or would that defeat the purpose?

Either way I want them.

I feel your pain, I messed up on the input cup relief on my Monitors. It is something no one else is likely to notice but we know its there.

Those are going to look fantastic!

[ruseriousclark]

Amazing coincidence!!!

I had been looking at Tony's page for about two weeks, and at the Cup-o-soup mark up in particular. Just came here looking at potential 2-way designs to try and use.

I think I recall Thomas mentioning crossover design where faceted cuts on the baffel are present being particularly demanding/complex.

I'll be very excited to see how this turns out. I was considering a similar enclosure design using a variant of the Usher 701, The Camelion, or Mark K's Seas ER18DXT. I wanted something full range but non-floor standing and loved the look of that enclosure. Having built several 2-ways wanted a different look and loved the Avalon style box.

Curious about the driver selection...

With an 18L enclosure and the Peerless driver you are tuning around 30hz I'm guessing?

[gmed]

Progress!!!

I like the way this is coming out to be. Just like I imagined.

Images not available

[gmed]

more like 45 Hz.

[Hdale85]

Wow those will be gorgeous! Hard to beat your previous speaker build but I think you may be on your way to doing so.

[gmed]

Thank you my friend. They are different, but I am really liking this new project. Hope it sounds good. Im going to need some help with the crossover design.

[Hdale85]

I wish you were closer so I could hear them when they are done lol. Unfortunately you are very far away.

[gmed]

First one finished

Man that cabinet has got to be extremely solid!

What made you do the little notch between the baffle and the cabinet?

[gmed]

I goofed slightly, I made the enclosure 1/8" wider so it was 1/16" wider on either side so I tried to turn it into a positive thing and give it a look, I actually like the look more.

[stinems]

Dude, gmed....you're not supposed to let on that you goofed. Here I was admiring the little notchy thing, I thought it gave a really finished look; "machined" almost. This is the sign of a good woodworker: gracefully concealed mistakes. Way to go, looking good!

I'm excited to see a project using the Peerless HDS PPB line. I've got a pile of buyout HDS PPBs laying around at home and I haven't decided how to use them yet. Interested to read how they sound to you.

Cheers,

Sam

How much did the butcher block material cost you?

[CraigJ]

How much did the butcher block material cost you?

Is this it from IKEA?



Excellent work gmed and glad to see you have some personal time to build speakers.

Cj

[Hdale85]

Looks like it.... So 39 bucks for a ~50"x25" piece. That doesn't seem to bad. With the joints and what not looks like it would be very good as well.

[Face]

Very nice!

[gmed]

Thank you. I actually love the notch.

Hey, gotta turn negatives into positives, Lemon/Lemonade, wrong turn, take the road less traveled.... I like what came out.

Yes, the counter top is the one from Ikea. Because I do not have a truck, I bough 2 of the smaller size which costs $39, otherwise for $59, you get the same size as two smaller ones.

I have finished the first one with sanding sealer and Poly. Looks amazing. Wish you guys could see all the wood grains against the light.

I actually like it more than the translam.
finished pics to come soon.

take care

[gmed]

What is nice about this wood is that once you join the pieces together, because it is a butcher block made up of small pieces of lumber, you cant tell where the joint is. No need for veneer.

This is my sanity, this and photography, other than my family. I come home, go to the garage, fire up the table saw, then go back to work on the computer!

thank you all for the great comments.

[gmed]

BTW, I gotta say, the Festool track saw makes your work so much easier. If it wasn't for the track saw, I don't know how much longer it would have taken me to cut my pieces.

The possibilities are endless. any track saw for that matter, great piece of tool.

[savage25xtreme]

gmed, is this going to be a published design or something you keep all to yourself?

I'm about to use a Festool TS 55 to do the same thing, I can't wait.

[gmed]

I can publish the design, except I dont have a crossover yet, and I dont think I can design a crossover for it, I may have to use something designed by speaker city. They just make up a crossover based on the specs of the speakers, unless someone is willing to help. I dont have experience with crossovers.

[mackintire]

There are a few guys here that will design a cross-over for you. The price is usually: Shipping the drivers and cabinet to and from their homes.

If you don't get a response in this thread in a day or two. Make a new thread with a title that reflects your request.

[mtmpenn]

Hey GMed -

Amazing... They really look fantastic. Can you give some more details on the cabinet - like size and total volume? Also, is the baffle 2.25" thick? And what are the angles on those facets?

Also, are you in medicine? If so, what field, if you don't mind me asking. I'm a neurologist.

Mike

[Hdale85]

I believe he's a med student

[gmed]

No, IM a practicing family physician in San Diego. The days that I was building my translam speakers, I was in residency.

Nice to see other doctors on here

I will have to make some sketches. You can always call me if you want to discuss it.

Ill make some drawings and make them available , if charting allows!!!

[gmed]

the baffle is made up of 5/8" BB ply x 4 so 2.25"
the enclosure is 18L
ill get some drawings this weekend

[Hdale85]

The new one The old one looks like a cow in comparison, although a beautiful cow

[gmed]

well, you should hear it moooooo!
very nice moooooooooo!

[Hdale85]

I'm sure it does It's just round and voluptuous :B

In all seriousness though I loved your previous speaker, but this design looks so much better to me.

[gmed]

Thank you

I also like it. Now that i've built one, and the other one is all cut, Im thinking to myself, why did I build this?

[SpeakerGuy]

Had a chance to listen to your new speakers in stereo? Decided which ones you like better? Did you end up getting help with the crossover you were looking for?

[gmed]

I have not finished the second one. So to answer your question, I have not listened not it yet.

today I was doing some calculations again, and I realized that I made some miscalculations. I made the enclosure larger than 18 L I was going for. the enclosure is more like 22L. I dont know why I wanted 22L.

Now I dont know if Ill ever finish it. The speaker looks great. I put in a lot of work into it. I know I can put some blocks in there to take some space, but not the way Id like to do it.

I can change the design and put a different woofer, but Id have to find a speaker that would work with 22 or 21 L, and is slightly larger than the peerless.

[SpeakerGuy]

How about these woofers? :

Those have a larger VAS - they trade a slightly weaker magnet for slightly better bass response (I don't think they give up much sensitivity, would have to throw one of each (that and the regular HDS Nomex the same size) and compare them)...

If your cabinets weren't so heavy, so far away, and thus expensive to ship I would say ship me one and I'd be happy to measure both that and the standard Peerless Nomex HDS 6.5" woofer - both FR and impedance, then at least give a shot at modeling a crossover.

I would probably try to cut away more of the back of the woofer opening - at least on the top and the bottom. The first way that I can think of would be with an angle grinder. If you don't have an angle grinder of course a rasp would work fine - one of those "micro plane" versions would make it easy...
