Hello,


So my computer room, which is used heavily for gaming and music is quite small and shaped like a rectangle with a doorless entry. It is roughly 11 by 7 feet. My computer sits against a 11 foot long wall, with no windows on it. The entry is to my right, the wall behind me with many 3 medium sized windows, and the short wall to my left with 2 medium windows. Sort of an odd room for good audio characteristics. I have a Yamaha RX-E200 system with 2 nice large bookshelf Yamaha speakers and 2 12' Sony Subwoofers each with 150 watts SA-WM500's. I listen mostly to rock, and my 2 subwoofers are placed next to my desk, in the left and right corners of the room, so I am facing them, they are in front of me. The thing is the left side of the room, where the doorless entry isn't, picks up a lot more low end naturally than the right side, so I have to turn the volume up on the right sub and set the cut off freq lower. Because both sides pick up evenly naturally in the room above about 70 hz or so. So the sub on the left volume is lower, and cut off higher, the sub on the right cut off lower, volume higher. But when things get way low in frequency the sub on the right still cant compete, and I dont want to turn it up too much where its farting and the sub on the left is working at about 50 percent. If I put them both on the left I think I will completely tell that the bass is coming from there. If i run a sine sweep for the subs, sometimes in the highs the right sub dominates, then the left, and they go back and forth because of the room. I can tell where the bass is coming from easily seeing my chair is about a foot and a half from my mains and monitor, and my subs are about 3 1/2 feet away from me on the left and right. Any ideas? Installing a door isn't an option- seeing its my parents home. Thanks- Eulogy

you could move the left sub closer, or change the whole set-up of the room around, but without that door--not much is going to change.


i'm sure there are other situations, but i'm at a loss right now..

From what you described I strongly suggest that you use only ONE subwoofer. That way the bottom end will be more satisfying (and the aural cues wont be confusing).


The crucial thing that need to happen is that the sub must be invisible or must NOT call attention to itself when its spewing out those low notes.


Two subwoofers will undoubtedly increase your SPL but in your case it wont work at all.

From research done by Harman, one of the best arrangements for 2 subs is at the midpoint of 2 opposite walls. So, centered on the left and right wall or centered on the front and back wall.


.... and to lessen being able to localize them, set the xover point a little lower and make sure any ports are not pointed at your listening position.
