Rear speaker in reverbrant room
« on: March 26, 2014, 07:28:11 am »

Hi, is there anybody who has experience with using rear speakers (delayed & flipped phase) to mitigate reverbs in small hall (13x23meters)? Does it make any sense? Where should be those speakers located? Corners/center?

Btw, in my installation we can't use mounting brackets and hang tilted front speakers from the truss.. So I suppose the best solution is putting them on stands close to the wall on both sides of the stage.

Reverberation is a factor of the room and won't be changed, in fact the added speakers will likely just make things worse by adding more sources putting more energy into the room.

In addition to Brad's great information, time alignment - especially if you're trying to do some kind of active cancelling of reverb noise, ranges from very difficult to impossible.  You may be able to fix the problem for one seat in the house, but that will likely not improve the situation anywhere else and/or make it worse.

Better to treat the root of the issue - sound treatment, reduce stage volume, etc.

You cannot "cancel" reverb.

I require at least 48 hours notice to cancel any reverb....

It takes a reservation to get a D9 EQ?

So that's how long it takes to collect a bunch of dead cats and mount them to the walls.

I wish my brother was still alive, he would have loved this response, and he would have volunteered to nail them in place.  LMAO....
