Re: Room Acoustic Advice

Not really any fixed distance - more a matter of where you're sitting in relation to modal problems or direct cancellations off that wall - or just plain sitting too close - I would say 4' or so minimum pending room size.

Re: Room Acoustic Advice

What about making the riser into a bass trap? Any guidance with this or is it not worth doing. I have seen a few opinions on it but what is yours? Any construction tips? Looks like most put vents along the back and sidewalls if they make one.

Re: Room Acoustic Advice

Certainly that's something to get more bass control in the room overall, though it won't help a ton with specific issues off the rear wall - it's more for decay time control. Slots at any wall intersection will help as well as larger, irregular holes in the front plate of the riser (joists run front to back) in each cavity. All covers with carpet and the front gives you some control right behind the front row.

Re: Room Acoustic Advice

My room has changed slightly. I used to have a door on the rear wall going to the AV room. This door is no longer there. This will allow me to build bass traps in the rear corners now if it would be desirable. Is this something I should consider? I was going to put two in the front of the room. They are going to be triangles of OC 703/705 stacked from floor to ceiling. Should this be done in the rear or would that suck up to many high and medium frequencies? Should kraft paper or something else be placed in front of them in order to still have reflections?

Re: Room Acoustic Advice

Yes that would be desirable. I would agree with using some sort of facing so you're not killing the highs too much back there.
