In Reply to: RE: Help with dialing in a System (LONG) posted by jeffmathers on April 18, 2012 at 06:10:39
a) Did this system sound 'correct' in a different location? ie, did you just move to this house, or move it to this room? If so, the problem is likely the room. If not, did you checking speaker wiring for correct phase?
Get dollies with castors to help you move the speakers around easily, and use long cheap flexible speaker wire, so you can leave the system powered and playing as you move the speakers.
b) Try moving the speakers by 45 degrees, just to try it out. ie 1 speaker on short wall, one on long wall, firing along a sort of diagonal.
c) Try moving the speakers into 2 corners.
d) Try using just 1 speaker, and move it around. Bass from one might be cancelling out the other.
The goal is to see if you can get the speakers to sound normal in *some* location. If so, location tuning might. Otherwise, you will likely have to resort to bass trapping to prevent bass cancellation.

No, it's always been in this room.

I'm not sure what this will reveal. What am I listening for when this is accomplished? Are you saying that one of the speakers will start sounding right? If so, what then?
c) Try moving the speakers into 2 corners.
Yes, we have done this. Not much difference in mid bass reproduction.
d) Try using just 1 speaker, and move it around. Bass from one might be cancelling out the other.
We'll try this out.
Thanks for the tips!

An angled setup can often offset bass cancellation. For example, at last years Axpona NY, Jeff Joseph did just that.
What you're trying to figure out is if this is a problem with the room, or the speakers. Once you've identified the problem, then you can treat appropriately.
Another thing to try: move 1 or both speakers and amps outdoors, without any walls, on a deck say, and see if the sound is OK. If its still thin and lacking bass, you may have other issues. If its OK, then the problem is the room. You then need to get a bunch more bass traps, and try on floor and ceiling joints, not just in the corners. Realtraps have worked very well for me.
Ok gotcha. That makes sense.
May be worth trying the outdoors idea too.
Thanks.
