Chris A Posted June 29, 2018 Share Posted June 29, 2018 Try it first. Let us know what you hear (if anything). Then explanations can easily be made. <--I find that sequence of doing these sort of things works better--especially when it's so simple and inexpensive to try it.

rplace Posted June 29, 2018 Share Posted June 29, 2018 What I am visualizing when I read @Chris A post is a thick blanket folded up something like a top hat's "home plate" and put on top of both Khorns. Then maybe a couch/chair cushion on its edge leaning up against the pretty veneer of your bass bin. I'd try both and only one of each. Please correct my visualization as you see fit. 1 Quote Link to comment Share on other sites More sharing options...
Shakeydeal Posted June 29, 2018 Author Share Posted June 29, 2018 So this thing thing on top of the speaker doesn't hang over the edge, or it does? And the cushions just rest against the front of the bass bin? Am I getting this right? Quote Link to comment Share on other sites More sharing options...
Chris A Posted June 29, 2018 Share Posted June 29, 2018 The idea is to soak up frequency-dependent acoustic energy re-radiating off those surfaces without disturbing the direct-arrival energy straight from the line of sight from the horn mouths. A little overhang on the top hat is okay if it doesn't obscure the tweeter's horn mouth on the top. The fuzzier and thicker the absorbent material, the more effective it will be.

Shakeydeal Posted June 29, 2018 Author Share Posted June 29, 2018 Ok, got it. Now if this is effective, what are other options that will do the same thing while being "aesthetically friendly"? I reached out to GIK and they recommend their "gridfusor" for the ceiling, halfway between the speaker and the listening position.

Chris A Posted June 29, 2018 Share Posted June 29, 2018 I think that they're trying to make money. That's like changing cables to solve a room acoustics issue--you'll hear something change--perhaps, but the problem remains. The closer the absorption is to the source, the more effective it will be. If you place it on the ceiling halfway back to the LP, you'll probably just detect something changed using your ears, but the problem will largely remain. Adding absorption outside of the nearfield of the loudspeakers and listening positions usually affects RT60 of the entire room, and little else. Optical acoustics effects of the sort that you're likely thinking about usually are an issue in larger auditoriums and venues--so optical acoustics (ray tracing) will work over a wider range of bandwidths than in a small listening room.

At least the oncs on the ceiling? All this time I've just been imagining an improvement. Quote Link to comment Share on other sites More sharing options...
