Thanks to all who suggested the acoustic panels. Let me try Audiofan's suggestions first and see how things improve before pursuing those wall treatments.
Quick report back...
I moved the couch forward about 2 feet, laid down a large area rug in the center of the room and then re-ran Audyssey. The surround speaker trims have now inched towards closer to zero then before but the FL and FR are about the same as before.
The area rug helps tame the listening room a bit, it dampens the sound a bit and takes some of the harshness out. On Audyssey mode, the bass still sounded a little thin. So, I made a few iterations of changes, changing the speakers to all small, set crossover to first to 80 Hz and then 120 Hz with LFE+Main. I then gave up on connecting the two front subs to the SW1 and SW2. I reconnected the subs to FL and FR pre-outs. I moved the Hsu sub from basement to the back of the couch as the 3rd sub, connecting it to the SW1. Turned off the front subs and reran the Audyssey. Below is the before and after speaker level readings:
I then turned the front subs on and calibrated each sub of the 3 subs to be on the same level with the Radioshack SPL meter. The bass sounded better with music and movie, but the midrange and high frequencies sounded okay but lacks the sensitivity and the punch.
In the end, I adjusted all the speaker trims and brought the FL and FR to 0, the rest with relative trim differences from the Audyssey calibration. Now, I get the punch back and everything sounded better than before. That dreadful bathroom harsh sound is virtually gone.
It now makes me wonder what is the downside of manual trim adjustment?
BTW, did anybody find a way to copy the Audyssey instead of Audysset Flat curve to Graphic EQ? It'd be great if I could copy the Audyssey curve and tweak it just a little bit to suit the taste. I really don't care for the Audyssey Flat, the bass is too thin and copying the curve to the Graphic EQ would take too much work to get it to sound great. The Audyssey Byp. L/R sounds the worst in my mind, it boasts the bass so much that it sounds muddy and neglects the mid and high frequencies. Wondering how different MultEQ XT32 modes sound from your systems?
I'm really grateful to all of you for your input, now my system sounds a lot better!
