So, I spent the afternoon over at my buddies place trying to integrate two of my old XS15s into his system (using my old AVR - Denon 2113ci). We did not have a good day.
His room is 24x14x7, sealed, with 2 rows of seating (having 2 rows is something I don't have experience with and it is proving to be a real bear to try and get smooth response in both rows with just 2 subs). The rear row is about 3' from rear wall and front row is about 8' from rear wall. The seating can be moved back (up to 3'), but not forward. We tried pretty much every possible location.
We tried both subs up front in the corners - sounded good in front row, rear row had overwhelming bass. Measured OK, but lost some extension.
One sub up front (F/Left corner), one in rear (R/Right corner) - measured awesome in front row (basically flat to 8hz). Sounded a bit weak in front row, better in rear row. But, we had no headroom at all, compressing at ~100db.
Tried both in rear corners - sounded good in front row, but rear row was waaaaayyy too much!
in the front row (where he sits all the time), they sounded best when in the front corners.
Any suggestions? My first thought is that the only thing that is going to solve his issues is more subs. I think for now he should keep them up front and not be pouring watts into the LFE to save headroom. He could even stack them and get 6db more without losing much in terms of coverage in the front row...the back is another story.
Do you think some bass traps would mellow out the exaggerated bass at the rear of the room at all?
