Time for an AVR upgrade soon or still fairly new? I'd also consider adding a second sub for improved response an sound quality.
Thanks! I do not have SPL meter so I'll check out the Niosh app. The issue with the Denon receiver (X3300W) is that when I go to adjust levels menu where it plays tones, the test tone from the sub is super super quiet. It's normal through the other speakers, but if I were to just go by that tone level, i'd be setting it all the way up to hear the bass. So I'm not sure what's the best way to get the receiver to play noise? If I start Audyssey setup, then it plays noise through the sub just fine. It's just the levels menu with test tone where the tone produced for the sub is quiet. Actual content also plays fine too. Just something is off with my Denon receiver it seems...
I do have latest firmware on this receiver. Maybe it's time to upgrade... I got this receiver 3 years ago. It's been great, but in my current setup I need very good room correction. I'm not a professional myself, and the room is less than ideal. it's 5.1.2 but the positioning of everything isn't exactly reference due to limitations in the room. The sub is actually behind the right tower speaker in a cubby, and there's no space really for a second sub. I'll attach some photos to give you some idea. I'm pretty limited. I'm debating upgrading to an Anthem receiver since I heard they have pretty good room correction, just very pricey. But I realize room correction can't fix bad placement.

Really? I noticed in LFE only mode that there's very little bass at all, especially with music.
I did read that LFE+MAIN setting only applies when front speakers are set to large. I set the towers to small since that seems to be the recommendation I'm reading everywhere on this forum, to let the sub do the work it was designed for. Since I set towers to small with crossover at 80, does it make any difference to set to LFE only?
For anyone curious, I have F36, C25, C763L, S206, and B10
