Bass management problems.

Last night I took the time to rewire my new PSW1000. I have tried the suggestion of wiring the sub using the high level inputs rather than the sub out on the receiver.

Prior to this I used to take the lazy route and just let the receiver make all adjustments due to spending most my time on the 2ch rig. Well now that I rewired I wanted to take the time to make all the adjustments myself. So out came the DVE disc and the SPL meter. The problem is I have discovered that my room has rather large peaks at around 40 and 80hz about 8db. Due to this problem I have not even gotten to tuning the sub yet. At those frequencies the LSi15s by themselves will shake the room. The room is about 12' wide and 27' long with 7' ceiling. Speakers are about 8' apart and 20" out from front wall. The carpet as of now is a short almost commercial type nap without padding over concrete (basement room). For seating I have a large leather sectional, and my listening position is almost dead center in the room. at the back of the room there is a 8' by 8' section making the room an L shape.

Just curious if there are any inexpensive solutions to my problem. I do plan on putting in much nicer carpet with padding sometime in the near future. Will that help much???

Any help would be much appreciated.

OK so I have been tinkering with this some more. I still have not been able to reduce the 40 and 80hz peaks. However I have found a new problem. In this system the PSW1000 is almost worthless. The LSi15s will hit around 100db down to 30hz even with my modest receiver. And as many already know the PSW1000 is basically worthless below 30hz. So as of now it is basically just taking up space.

So what I'm considering trying next is passing the speaker cables THROUGH the sub and trying the 80hz filter for the mains. Any thoughts on this?

I have a feeling I am just going to end up getting rid of both the PSW 650 and 1000, and move up to either an SVS or build an IB using the neighboring utility room.

Any thought or suggestions on my situation?

Thanks

Electronic crossovers (like the one in your receiver) typically perform better than the passive filter that the sub plate amp will use. Are you able to set your front speakers to Small and set the crossover on the receiver? If you can, try setting it at 80hz. That crossover point just might cause a bit of a dip at the 80hz mark, maybe enough to offset the peak, or at least help it out.

Then again, you may have more success running the front speaker outputs into the sub. It varies from one setup to another, so it's often easiest to try several options and decide for yourself.
