There are specific ways to place them based on research/testing that a number of us have been trying and it turns out they really work. This is not the typical suggestions about sticking one in a corner, or doing the "sub woofer" crawl to try to find a spot in the room that works for one listening position. The idea is to use multiple subs to create a drastically more flat low end response across a large area in the room.
What acoustic treatments do you find effective in these small room modal frequencies? We have tried a bunch of approaches but they all were less effective and actually cost more, I am hoping you can show us something for less $$ !! We just want what works best, fits in a small room and cheaper than multiple subs and DSP would be awesome!
I'm not suggesting that multiple subs doesn't help with flattening the low end it most certainly does help. But it's only half the solution. No bass trap can target very low frequencies "efficiently," because no matter what approach you use it will be very large and take up a lot of space. But porous traps can still have a profound effect as low as 30 or 40 Hz and most definitely do stop time related bass issues faster than ignoring that ring. Two subs makes the ring worse and higher up the bass region too, so you still need to compensate for it. Literally sheep's wool in wooden frames as deep as you can make it, floor to ceiling will cost next to nothing to make as deal with the issues. The less square the room is the the better the situation will become.
