That ~32Hz peak needs to be brought down either via placement or EQ or both. That is the bass managed portion of the cc+sub measurement and will show up in the LFE channel too. It might also be...

I'm interested in seeing how your current setup measures. You'll also be able to do compression sweeps like I did yesterday to see what max clean SPL at 20Hz your sub in your room can do. Just...

So I have the sub at +6db from what MCACC set it to, and I was listening probably a bit under reference. Is that not reasonable? Also the more I've read about this this morning, the more I see its...

I had the sub about 6db hot. I always calibrate to -6 and then boost it up to 0. So it was at 0 and I had the volume pretty loud. My receiver counts up from 0 and I had it at 55. Not sure where that...

The 10 Hz tone would not have been the issue for the LV12R as it is rolling off most of the signal by then. The 15 Hz tone is right below tune and would likely have caused extreme excursion.

My 2 guesses would be either the driver bottomed out OR, more likely, the amp received too hot of a signal and a...

Depends upon how much voltage the amp is putting out, but generally speaking using both inputs is safe. You're essentially doubling the signal strength on the input side of the amp. That could...
