I didn't want to leave this comment dangling on a negative note. Erich located his stock of small EOS waveguides that were listed on the old diysoundgroup.com site, and went beyond the call of duty to make sure I got what I was looking for, for a nice price. A pleasure to deal with, if you understand his busy-ness and have a bit of patience.

Nice catch.

I've built speakers with the QSC waveguide, the PRV clone of it, the 18 Sound XT1086 and the Pyle PH612.

Some random observations:

1) this appears to be the PRV clone. It has a different mounting plate than the QSC

2) the BMS and JBL ring radiators work exceptionally well on the PH612. (It was designed for them.)

3) the XT1086 is basically my "go-to" horn. The other two are nice, but the 18 Sound is hard to beat at it's size.

4) if you can live with a big cabinet, go for the QSC clone

All of these waveguides have measurements in "the great waveguide list"

That is definitely the horn I plan to go with. I suppose the design is going to end up like an econowave. I have yet to measure the Thiele small parameters of the 15"s I have. I got the cabinets for free with blown piezo horns, here is what they are: PS-115 Full Range, 2-Way Speaker With 15″ Woofer, 5″x15″ Horn – Nady Systems, Inc.
The stock horn with stock drivers sounds absolutely horrible and they actually posted a FR.

Patrick Bateman - Have you tried the Peerless DFM2544 with the QSC/PRV/B52 waveguide? I was hoping that with the relatively large Xmax (0.3mm) I could get the combo to go down low enough to meet up with a JBL 2226. I'm not too concerned with the CD's non-linearity as I can EQ with DSP (it will be an active system). I am planning to build a sealed 2.5 foot^3 cabinet placed right up against the wall which should net me an f-6db of 35Hz. Add a little DSP low frequency boost and it should be OK without subs for music.

My plan B is to go to a 12" mid-woof. Perhaps a Dayton PA310, or if win the lottery a TD12H, both of which could reach a little higher (~1kHz)
