Living room/studio - acoustic advice please?
I've recently moved into a flat - due to limits on space I need to adapt my living room so that it is usable as a studio for my music production, whilst still being usable as a living space...
Unfortunately it currently sounds awful, and I really need to install some acoustic treatment which is going to improve matters, whilst not reducing my living space too much.
The room is 16' by 11.5' - the "front" of my studio setup is a 16' long solid wall with my computer desk and speakers roughly midway along. The rear is the other 16' length which has an open doorway at either end and a sofa in the middle. The left wall is a large exterior window and the right also has a doorway.
The main problem is the 11.5' depth, with the speakers backing onto a hard wall and firing against the hard rear wall behind the sofa. This results in a massivly long boomy reverb tail at 50Hz, with strong modes at 100 and 150Hz. Bass frequencies are almost non-existent at the listening position due to cancellation. There's also some ringing at higher frequencies caused by the hard walls.
Ideally, I guess one would install lots of big bass trapping on the rear wall to try to tame the low modes, however I don't want to lose too much depth off the room. 10-15cm would be a sensible maximum. I could put some larger traps to either side of the monitors...
Can anyone suggest a good DIY trap design to tame that 50Hz boom, which doesn't involve putting something huge/thick on the rear wall?
