15" woofer waveguide

[zedda]

Hi 🙂

I want to built a 2way pro speaker with a 15" woofer...
The woofer need 47 liters for a optimal 63hz tuning...
Very small cabinet, and it's impossible to make a cabinet with a xt1464 horn (too deep to stay in the cabinet)

If I use a waveguide for the woofer like limmer 085, I can draw back the woofer and automatically the high horn stay in the cabinet...

What does a waveguide for a 15 woofer deep like this?
Sound better with or whitout?

A Limmer 085 - 15" Hornflare is too short to do much of anything other than a slight boost in the 400-1200 Hz range, which most would consider sounding worse, "honky" sounding. The upper mid sensitivity increase would result in slightly less distortion and power compression, if equalized flat it may sound better at high drive levels than without.

Thanks very helpful 🙂
If I want to do a conical waveguide using a handled milling machine, the different angle of coverage of the high horn and the woofer horn is counterproductive?
