I've been dissappointed with the sloppy bass of my new HT system, especially for music. System consists of: Onkyo TS-DX696 reciever Sony DVP-NC600 DVD player (relatively low end - $230) HTD Level III 5.1 speaker system (not towers) This is in a large room (6500 ft^3)(20x25) with vaulted ceiling slanting from 8 to 16 feet high in the 25' direction (which is also the 'front' of the room where main spkrs are positioned). Seating location near middle of room. I have all speakers set to small (claimed response for the mains & surrounds is 43-20k, 30-250 for the 12" sub) and the sub XO set to its highest setting. Initially I was attributing the problem to a deficiency in the subwoofer; then I've taken the following measurements (these ARE corrected for the RS meter) using the Avia sweep. HZCorrected SPL 180 75 150 71 130 71 120 82 110 82 100 77 90 91 80 90+ (over range) 70 90+ (over range) 60 90+ (over range) 50 86 40 80 35 79 30 79 25 29 There is a sad dropoff around 130-160, and a WICKED peak between 50 and 90 HZ. It looks like the best investment to rectify the situation would be an EQ; I suppose that even a great subwoofer would not really do any better in this room? What would be a good (but economical/good value point) EQ to compliment my system? These measurements were taken with sub on the front wall; moving sub to corner or under coffee table resulted in similar sloppy sound,although I did not take measurements for these locations.
