Do come & listen. I'll run them full range with no BSC or other circuit, and no subwoofer..just full range.
Hope to see you all there!

The design is like a Voigt Pipe with an extra fold that
fires out the top instead of the bottom. When placed in a
corner, the walls load and essentailly increase the
flare of the horn mouth or terminus

With the driver specs that you have the gang that's
building the BIB site at:

http://www.zillaspeak.com/bib.asp

can give you some dimensions.

One design element of that site is it's not real clear on how
to move around. Click in the red "how To Build a BIB" to see basic design principles. Click on the speaker logos for alignments and
specs for individual drivers.

Have fun.

I have never actually indulged in backloaded horn construction, and this is my first real experience with one. I find this PAWO horn to ba an elegant design (in terms of space) and more to the point, sounding SIGNIFICANLTY better than a BR box in terms of bass.

I will bring a pair of bipolar MLTL speakers to the GPAF which uses the CSS FR125S and WR125S (one per side). This is a true full range speaekr with BSC built in. Bass to 40 Hz.

1. The driver has a rubber surround and is capable of some serious Xmax. It also has a paper cone. IF you run it "pure full range" it produced very decent bass down to about 45 HZ, but the driver really works it's little tush off, and this causes the highs to become edgy.

2. Crossing it at 70HZ with a 24 db Xover, and a sub greatly reduces the Xmax and smooths off the highs as well. I think that this is a must do with this driver, unless all you like is acoustic/jazz type music at moderate levels (in that case pure full range will do).

3. The driver box combo is capable of 45 HZ which gives us almost an octave to spare if corssed at 70 Hz. This leads to better integration with the sub.

4. The reason I bought this was that when crossed with a sub, this is a very musical driver, with great performance in a small to medium sized space. It's efficiency is about 90 db, and it can handle 20 watts. THis makes it go upto pretty loud levels, and the dynamics are pretty good for a small to medium sized space.

5. The cabinet itslef is very elegantly designed in terms of space saving.

Just my thoughts on this" my latest acquisition! I'l lrpobably run it in my office with a cheap sub.

I am glad that you bought these speakers. I know from what I heard from them at the show. They will provide you with alott of musical enjoyment.

I was thinking that these drivers could make a killer line array.

Thanks for all of your efforts at the show, it was fun and infomative.

Also, what DBX model Xover were you using?

Thanks,
Shane

He is a single driver fanatic, and has built all sorts of stuff. He is selling these drivers (with plans for the horn that are free off the web anyway) for $40 a pair. Just to clarify, I have no commerical interest in this whatsoever, hence am posting it here and not in the SWAP forum.

Drop him a line. He is a nice guy.

My DBX crossover model is: DBX 234. It was made in 1999. Not sure if DBX makes it today. It's an analog stereo 3 way crossover. Other companies that make these are ART, Behringer, etc etc. IF you awant to spend more bucks, get a Rane. DBX is good middle of the pack.
Hope this helps!
