According the the official MCACC thread on AVS, you should do the following (I am summarizing greatly here so recommend you check that thread for more details):
1) Run full auto MCACC. This will set the speaker distances, levels, do an initial read on the room, set up equalizers, etc.
2) Go in an check your speaker settings. For whatever reason it almost always sets the speakers to 'large'. Change it to small, adjust sub crossover, etc.
3) Go back and run MCACC again. Do not run Full Auto MCACC though. Instead just run 'Auto MCACC' (yeah, great names?) and select 'Keep Speaker Settings'. This will re-run the equalizer programs but now with the speakers set up properly.
4) There will be a 3 different versions stored in your presets - Symmetry, All Channel Adjust, and Front Align. Each will produce a slightly different sound based upon which speakers are used to calibrate to. Just pick the one that sounds best to you. Personally, I don't hear much difference but prefer All CH adjust.
5) If you still aren't getting the bass you are looking for, adjust the SW Channel on the AVR up 1-2dB.
6) If you are still not getting the bass you want check through the following:
a. is your sub turned on? is the volume knob turned up high enough?
b. is your low pass filter setting right on the sub? You want this to be at max so the AVR is the one doing parsing of signals.
c. check the phase selector on the sub. Pio suggests setting it at 0 but switch it to 180 to see if that corrects the sub.
d. turn on/off phase control on the AVR itself
e. Toggle the standing wave control on the AVR (under audio parameter menu) and see if on/off produces more of the boom you want. Standing wave control is designed to reduce too much boom but it might be overkill for you.
f. try moving the sub to a new location. This may be the most important part of producing the right bass.
g. you can also go into Advanced MCACC and change the reverb settings for the room. MCACC tries to equalize the sound and sometimes in a room with a lot of bare walls, windows, etc., it can overcorrect. You can adjust this by reducing the time delay settings (check that MCACC thread for more details) which will then apply the equalizers before correcting for the reverb adjustments.
h. If you are happy with the sub performance but not the bass from individual speakers then you can also go in and adjust the equalizer by speaker. For example, if my surround L sounds like it doesn't produce enough bass I could go in and increase the dB at the 63hz level and other low levels to produce more bass. NOTE: doing too much of this is going to throw off the room balance but if it sounds better to you then do it.
Bottom line is that this AVR should produce plenty of bass for you.
