A few ideas to get your creative juices flowing:

Since you have two maybe you may consider a bipole design of some kind...

http://homepage.mac.com/tlinespeaker...es-wVeneer.jpg

Or a modified wide baffle transmission line like this...

Or maybe something like this fostex design with built in stands (scroll down to see)...

The spiral speaker is usually made using foxtex but i see no reason not to do with TB...

The Cain and Cain Noogi is nicely proportioned too...

Otherwise those would work nicely in simple ported boxes.

It so happens that I have four of these drivers, too. I've tried them in a tiny BiB (oxymoron) tuned to 70Hz and got no output. I then used all four in a bipole tuned to 60Hz and got some actual output. The sound was pleasent but at times sounded strained (no big suprise), however, I will add that there is output far past advertised X-max with no audible distortion. For my next trick, I'm building the Yellowplay for these. Yes, I know I've joined the ranks of people who can't use the driver a horn or BVR was intended for, but two W3s per cab with an enlarged CC looks like it will work. I'll simply delete the one interior panel that defines the bottom of the chamber and go from there.

I was able to up and stop drinking after living the rockstar lifestyle for fifteen years, but I can't stop building cabinets!

In the works-

Oliva
Half Chang (almost finished)
Buschhorn
Z-Horn
OB for GW 8" and 15"
linear array to use up all the NSBs and ND20s

Somebody stop me!

Sorry, just had to get that off my chest. You build a TQWP and I'll build the Yellowplay? We'll compare notes.

What are the big suck-outs from ~ 65 - 85Hz & 150 - 200Hz?

Looks very interesting, wonder if I can get any dimensions and plan.... I am absolutely lost in designing volumes from the parameters...

we have the same disease..., no cure I am afraid. Hopefully nonprogressive illness.

gychang, I'm afraid that it is a progressive illness, and here's the proof...

O.K., hm, I'll bite. I'll build the design that you linked so I can get useful output at 35Hz from a driver with an Fs of 110Hz. There is a weird quirk on your website, though, and I can't figure it out. The plans for the horn are incomplete and there's a link at the bottom of the page that says the rest of the plans are available for a $30 fee. This must be a misprint because, after all, I've seen you post plenty of times linking to your designs and you couldn't possibly be just trying to make money from the people asking for advice on a forum where the spirit is the free exchange of ideas and helpful input. So simply e-mail me the plans and I'll build the design, document it's assembly, measure the results, and report back with my listenning impressions and numbers within a week or so. I'm looking forward to completing another set of speakers whose design was furnished to me through the spirit of kindness and enthusiasm that we all share for DIY.

Or I'll build the well documented Yellowplay modded for two drivers.

Hello,
read the plans again, they are complete to built it
without the part list, sorry

If you want to built for a test, better take the CORNET,
it easier to built, for a test please show us an inside foto, to know the right sizes and material, than you can get a partlist for free, if you need it.

thanks, I will send an email. I do not have a web site, just a photobucket account where I put the speakers to view.

Deal with the wife is I get rid of a speaker if I want to build one, so give them away to friends. Lots of demand for free.
