generally speaking, you should turn the crossover on your sub up all the way and then handle bass management with your receiver.

What crossover do you have set at 40 in your receiver? what speakers do you have?

If 40 is the crossover for an entire surround system it may be too low for the center and surrounds.

no no, crossover for the sub is set at 40. I have a harmon kardon avr-247 for a receiver, m-80s for l/r vp-150 for center. Auto eq set crossover for the sub at 40. I'm not home at the moment, but I swear I can tell a difference when I play with the crossover on the sub, tho as I said before that could just be because it sucks. It just sounds to boomy with the sub crossover set at 150. I'm thankful for the help, I know I'm asking really basic newb questions, but It's so much easier to ask people that know instead of looking it all up, and thus far you axiom forum guys have been really helpful.

Steve, if you get the EP350, the sub low-pass filter(it's not a full crossover; it just rolls off the sub above the selected frequency)should be set at 150 to get it as far as possible out of the way of the full crossover(e.g., at 80Hz)that the receiver is doing. The speakers will then be rolled off under 80Hz and the sub will be rolled off above 80Hz(getting the under 80Hz sound from the speakers set "Small").

Thank you.

When you get a chance tell us what speakers you have and what the crossover setting is in your AVR for all speakers.

will do.

If the sub crossover is set at 40 then the M80s are also set for a 40 hz crossover. I would recommend turning these 2 settings up to 60hz once the EP350/500 arrives (even now just to see if some of the boominess disappears) and let it do the hard work to free up the receiver/M80s a little. I can't remember if the H/K has a double bass or LFE+main setting if so this feature might be turned on which can also bring about boomy bass.
