What are the dimensions of those waveguides? They look to be about 22 inches wide by 14 inches tall by 10 (? complete guess) inches deep. Did you make them yourself?

That little A2S driver (that's what it looks like anyway) only has a sensitivity of 78dB at 1W/1m and Fs of 150Hz. You should try different drivers. Horn loading the Tectonic Elements TEBM35C10-4 would be pretty interesting. With slightly better sensitivity and more xmax it might have even more dynamic bass. There are lots of other 2 inch drivers out there that are more sensitive as well.

Bushmeister's horn crosses much higher than most FAST designs tend to.

The Aura NSW2-326-8A would be interesting to try and are pretty cheap. Higher sensitivity and much more x-max. The dropping top end might need more EQ or not work at all on the horn. Looks to be almost identical physically from the front.

The horn is a tracrix expansion with dimensions 24w x 16h x 21d in inches

I wil be trying other drivers soon. The SB acoustics one should work well

Yes, thats how I found out about the SB acoustics driver. Your solution is more sophisticated than mine with the multiple drivers acting as a point source in the one horn. My setup is the lazy mans "synergy"

Yep, that driver looks good for this application. I might give it a try as well. Thanks

That's a lot deeper than it looks! Did you make it yourself?

Looking forward to your comparisons with other full range drivers mounted in that horn.

I've experimented with loading several small drivers in various tractrix horns. Works very well. The problem is directivity of HF response and lack thereoff in bigger drivers. You either go for "magic" mids, or amazing highs or just build additional horns for seperate drivers. I've had best results with loading a 30 cm x 30 cm square tractrix loaded with 1" alu driver, with highpass at cca 800-1000Hz.

I aquired the horns from a local DIYer. They are made of stacked MDF fillets and sanded smooth. I dont have the time or patience to build curved horns myself
