3-Way Horn System
This combination of readily available and easy made items is the result of 5 years of iterations. The aim was getting best audio-reproduction realism in a dinning-room with reasonable cost. And time is pretty cheap for an DIY amateur.
A pair of 70Hz down-scaled "Show Horns" by Bruce Edgar were combined with 90x40 trumpets. Digital processing was used to cope with acoustic path mismatch, crossover duty and room-correction. Class-D power modules were preferred while output autoformers adapt professional equipment range to home usage.
Multiple 6th-order subwoofers were deployed after Earl Geddes method. Tactile transducers were provisioned under the coach for greater impact on movies and music (piano, percussion).

- Thank you both for the kind words!
@Ray
If I would ever have a bigger room, my system will look most like your uncompromised system.

- I have changed all Behringer processing to an all-in-one DIY solution based on miniDSP and APart stuff.

- Nice work! Did you use EVM12L like Bruce Edgar? Think about same project from 80 Hz, but too slowly learn HORNresp for re-sizing original 50 Hz box :)

- Thank you. I didn't use Hornresp but I reduced all liniar dimensions by 1.4 to convert "Showhorn" to 70Hz. Consequently, I am using an 10 inch driver instead of the original EVM12L. I don't remember the code, but it's an Selenium with 2xFr/Qes more than 500Hz.
You can use any 10inch driver looking for not too low Fr (about 60-70Hz) and high Bl. Good luck!

- -update-
I begin using FIR filters (LR48dB/8) for the Mid and Hi ways (Bass and sub-Bass remain on IIR LR47dB/8). Both listening and measurement confirm the improvement which I describe as more clarity in dialogs --no need to increase volume to understand it-- and smoothness of the high spectrum.
Also, I have tryed FIR of greater orders (96dB/8, 192dB/8, 384dB/8) but highs became more and more aggressive.

New strait midbass horns that improve balance on cellos and low voices. These new horns are ready-made outdoor speakers by Audac but the low-end horns are just perfect for my use.

- Hello, I love your horn system, amazing work, and great looks! Can you tell us what you are using for your speaker drivers and which horns you are using?
Best Regards,

- Thank you Dean! For Mids I use Selenium D405 on HL47-50R horns, Eminence APT 150 as tweeters and Audac HS212 for midbass. Crossover frequencies are 100/500/5k.
