Audyssey put the L R at +1.5 and the center at 2.0 I think. It seemed to have created a bit more of a disparity between the sub and sats.
don't change the volumes, that is just what is necessary to balance all the speakers. It is not creating any "disparity". The sub/sat blend is going to be determined by the crossover frequency, but most importantly the positioning of the sub and how it interacts with your room acoustics.
SW is set to +3.5db and I could hear it in a lot more of the programing. Not sure if I'm totally happy with it though. It seems to be a little bit boomy but that could be settings I have yet to adjust.
the primary cause of boominess is poor positioning of the sub -- if you have time, you may want to experiment with different positions and see if another spot provides smoother response. Also, if you didn't yet, running all 6 positions will give Audyssey MultEQ more data to work with in smoothing low-end response.
if the boominess is only with cable TV programming (and movies sound fine), you should lower the Dynamic EQ Reference Level Offset (Parameters > Audyssey Settings) down to -10dB. This will lessen the aggressiveness of the "boost" that Dynamic EQ is doing to your sub.
I'm not sure what normal settings are for the sub but I'm thinking about putting the speaker settings back down to 80 hz
What speakers do you have? There are no "normal" settings, the point of the Audyssey system is to measure the response of YOUR speakers in YOUR room (not any spec on paper), so don't assume 80Hz is the "best" setting for your specific setup.
or drop the sub down to 80-100hz to smooth it out a bit.
Don't touch the knobs on the sub after running Audyssey. The crossover is bypassed and all the bass managment is controlled by the crossover freq. you set for the speakers.
For the most accurate sound, Is it better to raise the +db on the sub and turn down the sub volume or turn up the sub volume and turn downt he db?
Neither is more "accurate", the combination of the digital signal gain and the sub's amp gain will produce the same SPL in the room (assuming you equalize the volume after fiddling). But as I said above, after Audyssey you do NOT want to touch the knobs on the sub. If you want to tweak the bass, adjust the SW channel level in the AVR.
I also have the port facing me, I'm thinking I dont like it as much that way, I'm going to experiment with the position so I cant clearly pick out the rumble cause right now I can.
What sub do you have? In general, the port should face a wall (ideally with at least a foot of separation to prevent boominess).
