garyc_06820 Posted February 11 Share Posted February 11 Hi, I'm building walls for recently acquired Klipschorns. My question is how far out should the wall extend? I haven't been able to find the correct wall length that completes the bass horn. Is it 42"? 48"? I want to get the full frequency extension, but don't want to extend into the room more than necessary. Thanks in advance! Quote Link to comment Share on other sites More sharing options...

garyc_06820 Posted February 12 Author Share Posted February 12 Travis - thank you for this. I have seen this before. I have also seen some similar designs that are somewhat shorter than 48", and of course the inside dimension here is more like 44". Since I am actually building walls, I am just looking for the actual dimension that gets me the best extension that the klipschorn is capable of. Lol, as with all this stuff, the pursuit of perfection - that you can never achieve! Quote Link to comment Share on other sites More sharing options...
Schu Posted February 12 Share Posted February 12 that's 48" from the corner, not from the horn exit. Quote Link to comment Share on other sites More sharing options...

Well the DPH paper say’s Neglible Improvement past 4ft so whatever gives you peace of mind 🙂 1 Quote Link to comment Share on other sites More sharing options...

garyc_06820 Posted February 13 Author Share Posted February 13 Interesting idea. Well as it turns out, the Klipschorns are either side of an alcove. The rear walls will only end up being about 42" before they recess into the alcove. If I move the speakers farther apart, the imaging suffers. One side wall will be 48". The other will be longer about 13' in order to divide the room from my workshop area. I guess I will try to measure the frequency response for each speaker once complete. They sound good now, but I'm using the loudness and bass controls to artificially get the bass where I like it. I'm hoping once done I can ease up on that boost. Btw these are 1978s with backs added and Volti mid horn and tweeter upgrades Quote Link to comment Share on other sites More sharing options...

the real Duke Spinner Posted February 13 Share Posted February 13 BTW I would insulate that construction Quote Link to comment Share on other sites More sharing options...
Dr Morbius Posted February 13 Share Posted February 13 My corners are 20.5 feet apart and each corner has 8 inches on centers instead of 16 inches for 4 feet out in back and sides. Pretty solid. 1 Quote Link to comment Share on other sites More sharing options...
