How hot do you run your sub(s) if not listening at reference level? I run mine 6db hot.

4 db. Beyond that, it starts to feel unnatural.

I run my IB flat with a LT boost. It gives a more natural feel but with the same visceral effects of running the LFE 7 dBs hot. Basically boosting the low end only.

I run mostly flat with the occasional + 3 (which may be flat due to correcting the after Audyssey level) to +5 which may only be +2 db over flat, make sense biggrin.gif

May be a dumb question, but how do you know when you are running hot? What woudl be considered normal i guess?

You are running hot if you turn up the trim in the avr, on the sub, or use excessive EQ. I don't run my subs hot th95% of the time. I will occassionally use a 3 db boost on the trim in the avr. Running the subs hot decreases headroom so be careful.

Depends. With dynamic eq, I'm +3 dB. Without it I'm at +7 or +8.

Getting used to dynamic eq...definitely like it for surrounds and highs, but thinking I might prefer the entire lfe channel the same hotness (+7 from 80hz on down) as opposed to a gradual LT shelf like rise.

Still playing though...

I run my sub pretty hot as Audyssey sets the trim levels really low. Gain knob is generally 1/4 turn (9 o'clock position) and between -7 to -9 in the AVR. I probably run 6-7 dBs hot.

Some people try to run the sub hot to get more tactile feel. The sub may be falling off in the LF. Something like the Mini DSP for EQ may help.

0 db. I leave my Paradigm Servo 15a set where my Pioneer Elite SC-75's advanced MCACC set's it. Shakes the room when needed and calls no attention to itself when it shouldn't.

Even though MCACC does nothing to the sub below 63 Hz, it does and incredible job in getting the bass in the system to sound great. This is especially true using the 3 mic position. IMHO the standing wave feature is as important as sub EQ.
