The -3 sub level offset is fine. I'd raise the sub's gain knob a bit and rerun your room corrections first mic position. I like an offset around -6 /-8 then I raise it from within the receiver's manual speaker level settings 4 to 6dB but staying below 0 dB to avoid clipping the sub amp. That's running the subwoofer several dB's above reference or a bit "hot" and leaves the sub's physical gain knob alone. Any corrections from then on can be done from the receiver to maintain a baseline you can easily return to reference with in the receiver( the original -offset.)
My first instinct is that louder is better. After the auto setup was complete, I turned the gain up all the way on the sub itself.
Louder is better based on how we perceive sound based on the equal loudness curve which prefers a bit higher level with low frequencies but it should be balanced with the other speakers so that you're not 13dB or more above reference on your subwoofer. That's a space and power issue with your current setup I believe.
I haven't done a sub crawl, actually going to go check out a video right now how to do that as i've seen it mentioned in a few places. Speakers are set to small, however when I turn the lowpass filter all the way clockwise on the sub, it begins to sound a bit murky.
The " sub crawl" could help but the room is still the room and the sub's low pass filter should be set all the way over to it's highest setting so that it doesn't interfere with the receivers bass mgmt which sets its own crossover for the sub( usually 80hz and 120 Hz for the LFE.) It shouldn't make the sub sound anything with bass mgmt. turned over to the receiver.
No adjoining rooms, this is a converted garage separate from the house. I paid $450 for the J-112
Good, then it's sealed. That's a help acoustically speaking. I'd return it if you can. Better price/performance out there in Internet Direct subwoofers like Emp-tek, Rythmik, HSU, SVS etc..
