Would a pair of SB-1000s be a good match with my PB-2000? My room is 16x10x7.5, so I've got some pretty nasty room nodes. I've attached a graph that illustrates the issue, though isn't entirely up to date (it was worse before I added bass traps).
With a new MLP and speaker placement my main L+R are fairly flat down to about 50Hz and then trail off. When I add the PB-2000 I end up with nasty nulls at 80Hz and 120Hz (the 60Hz null in the graph has since been pushed upward).
Following the suggestions proposed by some of Earl Geddes research, I'm thinking of using multiple subs to even things out.
No matter where I place my MLP or speakers, the response in my room from about 40Hz down doesn't seem to change much, which seems somewhat consistent with my research.
What I'm unclear on is if the SB-1000 (or multiple units) will help iron out this region, or if I'd need something that reaches lower. The room is small as it is, and I'm scratching my head as to where I would place anything as big as another PB-2000.
My focus is split 80/20 music/movies. I listen to music in 2.1.
Having nulls at 80Hz and 120Hz is annoying and a problematic region. I can get rid of the nulls by using a 200Hz crossover, but then only if the sub is located behind the MLP. This makes the sub locatable during music listening and very distracting with it behind me! I need my 80--200Hz originating from the front of my room, and the sub performs terribly up there.
a) would two or three SB-1000s help iron out both those problematic null regions?
b) would two or three SB-1000s help iron out what is happening in my room below 50Hz?
c) if musicality is my focus, is the SB a better fit in a small room than the PB?
