I need to know why two of these things don't sound any different than the Polk PSW505 they replaced.
This is the layout of my room:
With the volume knob at the 9:30 mark, YPAO set them to -5. I bumped them up to -2. I still have to crank the volume to fill the room with bass, like -5 to 0db on the receiver, where my mains are getting uncomfortably loud because the couch isn't too far away, and it still feels like there should be more bass, especially with two. No chest pounding, no vibrating, no drywall cracking...
Now this is all with music, but I'm testing it with bass-heavy music. It's just not there. Doesn't matter what port config or Q settings I use. I've tried level matching the subs to the mains with a UMIK-1 and REW's SPL meter.
On the other hand, some movies really make these things move, and you get the tactile feel of the couch shaking underneath you, but I feel like the subs are trying way too hard to do it. They only have to fill 1850 cu ft, and I have to run two of them 5db hot to do it? How can that be right? In fact, the one on the left makes terribly audible rattling noises during intense LFE if the volume is real loud (louder than -10).
What am I do wrong here? Is it possible my receiver is acting up? It's a Yamaha RX-A2000, each sub has it's own RCA port - no Y splitters or anything.
Am I just expecting too much? I listen to more music than I do watch movies so I would really like to hear these things shine.
Any advice is appreciated.
