Dave, you mention you have 3 subs. Have you calibrated each of them one by one to 75dB, or whatever db your other speakers are set? Also, are they placed around the room, or all up front?
Process:
Turn all subs off.
Turn sub "one" on, and calibrate it to 75dB's like the other speakers.
Turn sub "one" off, and turn sub "two" on and calibrate it to 75dB.
Turn sub "two" off, and turn sub "three" on and calibrate it to 75dB.
Then turn all subs on which will give you about a 5dB gain over the speakers, but that is what sounds great to me, and recommended in Ian's video.
For distance (delay) you have to average the distance of all your subs, it is best to try to space them equal distance from you, but that may be difficult, so just average their distances.
Then, run Audyssey.
