Looking for some suggestions/new ideas to overcome some bass response issues in my new HT room. I just got my 12x18 (x7.5) foot room 'mostly' completed and I've started tuning. I knew right away something wasn't right with my SVS PB-2000 (x2) as I had been using one of them in my family room while I was building this room. They sounded amazing but in this new room it was like listening to a soundbar sub at best.
I'm using a umik-1 with REW (Denon AVR, audyssey disabled, LFE crossover at 200hz and all speakers disconnected while testing). I've tested a single SVS at 11 different positions independently and measured at MLP. All 11 measurements are in the picture attached below. It appears my room hates 40-50hz
While some positions are better than others, it appears that this outcome is shared at every possible location to some degree.
Note 1: In the sketch the red boxes are the possible locations where these SVS subs can live (and that I measured). The orange boxes are spots I measured with the SVS but that they won't actually fit in. I have plans to add more subs there in the future.
Note 2: I did put a bunch of vents along the back of the room into my riser which is loosely filled with insulation. I did tests with them open and closed, didn't seem to make a significant difference (maybe 2db better opened for some of the positions)
Note 3: Unfortunately the seating can't move, it's a limitation of a 18x12 room. Starting to think bass response will be another limitation of that.
Just wanted to get a fresh look at what I'm doing or something else to try.
