This stuff gets confusing fast so I want to start with just a couple of clarifications. Anytime I type "calibration", "calibrating" or "room correction" I'm referring to Audyssey. When I say "sweep" or "measure" I'm referring to REW. I look a it like "we're using REW and the UMIK to measure the results of Audyssey's calibration". Audyssey does also "measure", but for the sake of avoiding confusion I won't be using it that way for this conversation. I think we ran into some minor confusion about that yesterday.
As far as we know right now, you've done one calibration without the app, and twice now with the app? Are both calibrations with the app consistent with each other?
When you first ran Audyssey it should have prompted you to adjust the gains on that back of your subs to level match. How did you handle the front 2? That just hit me. I only have 2, they're both up front and have their own preouts so they're independently level matched using Audyssey. You have 2 on one and 1 on the other. It just occurred to me that I've never attempted this myself and am now curious how you level matched the front 2. I don't know how much that matters, if at all, but I'm interested to find out.
@shadyJ,
@lovinthehd or
@William Lemmerhirt might be able to help shed some light on that for us.
Now in that vein next time you run Audyssey I would maybe purposely turn the gains down on all your subs so that Audyssey prompts you to readjust them until the pointer is in the green again. Sort of a fresh start. Maybe even do a soft reset.
HSU does recommend when calibrating those subs to do it with a single port open, EQ 1, Q .7. That's a must. After I run room correction and do all my tweaking I pull the port plug, run both ports open, EQ 2 and I've forgotten to do that a few times. I had to scrap what I had done and start all over with the proper settings. I keep with HSU recommended settings for sweeps with REW too when measuring.
Ohhh... check your phase switch too. That's a toggle switch and it's really easy to bump. It should be 0°. In fact, double check all your switches and knobs on all of your subs and make sure that your settings are in line with HSU recommendations. Crossover toggle "out" (bypasses your sub's filter so you can use your AVR's bass management), Q setting, EQ setting, all of it.
That's all I got for now, lol. Once you get set up and start measuring we can zero in closer on what's going on.
