1. should I set the sub back at 80 Hz instead of 160 Hz ?
2. will the sub get damage if I leave it at 160 Hz ?
3. is there anything wrong with the setting I have above ? What I am trying to say is: am I doing any damage to my AVR and speakers if I keep at current setting
FYI the basement is 18 x 12 with open way to the living room
Out of curiosity, what is it that wasn't working out with YPAO? It does more that set the levels; it also applies PEQ to try to correct for room acoustics. As to your points:
1. 160 Hz is very high for the crossover. Your speakers are capable of lower frequencies than that. Further, if I read your sub specs right, it only goes as high as 140 Hz (the highest setting it has). That means you must have a gap in the 140-160 Hz range with those settings. Personally, a crossover above 100 Hz has caused problems for me in the past. Deep parts of male voices will come through the sub and sound boomy or hummy compared to other dialog, especially if the sub is running hot. With your speakers you can set the crossover to 80 or 90 Hz.
2. The sub probably won't get damaged, but as I suggested above it might be filtering out frequencies above 140 Hz leaving a gap up to 160 Hz where your speakers pick up.
3. No damage, but I doubt you have achieved your optimal settings. Did you manually set the speaker distances in the AVR? The sub distance cannot be set with a measuring tape because the processing delay in the sub should be taken into consideration. YPAO generally sets the sub distance further than the actual physical distance to account for this.
The bottom line, though, is that you like what you hear. I'm just throwing out some suggestions.
