Room Acoustics Problem????


I'm hoping someone can provide some input to resolve what I "think" is a room acoustics problem. I have a HT setup in a rectangular shaped room approximately 20' (L) by 12' (W). My television and front speakers are located on the length of the room. Although I have 5 speakers in the room for surround HT sound, I listen a great deal to 2 channel as well. What I'm noticing is that the left speaker always appears to be louder than the right speaker, throwing the sound off-balance. After reading a few articles on room acoustics, I'm attributing the louder sound to the bay windows which are located next to the left speaker. I'm assuming the bay windows add increased reflections in the sound. The right speaker is located next to an open space so there is no added reflections from that speaker.

Is there an easy way of fixing this problem other than using the balance control to change the output? Would adding absorption materials near the bay windows (maybe curtains?) solve the problem? I'm hoping that I could come up with a simple solution without spending too much money. Any advice would be appreciated!

My guess is that the real culprit is the opposite of what you suggest. Am I correct in understanding you to mean that there's an opening or doorway in the wall by the right speaker? If this is the case, it's that hole that is most likely causing the apparent difference in volume. In other words, it's not that the left speaker is louder, but that the right one is quieter due to no first reflection, at all. While the windows will result in an increase in reflected high frequency energy, this usually makes that speaker seem too bright, as opposed to too loud, as the apparent tonal balance of that speaker appears to get shifted. In any case, the fix is still the same since closing that opening in the wall is probably not an option. Try what Newbee suggested (toe-in) and what you suggested (curtains), as well. Don't be afraid to use the balance control a little, either, to get it just right. That's what it's there for and it shouldn't hurt the sound quality since it is already in the circuit anyway (unless it's defeatable). Hope that helps.
