"Just for my own curiosity, you'd be doubling up some positions?"

I am not quite sure what you mean here... here will be 2x1 or 2x2 front left/right speakers, 2x or 3x center, and 2x2 side surrounds, plus 2x1 rear surround. Incidentally, can one use (larger capacity) regular speakers other than dedicated Axiom surround speakers for surround?

"Low Frequency Effects... the number after the "dot" or "point" in 6.1... ie: not bass... bass (<100-200Hz depending on your definition) exists in all channels... LFE denotes the channel mixed specifically for subwoofers."

Gotcha. So, "bass" is under 100 or 200 Hertz. And what would the "typical" freqency range be that is created for a LFE channel? Assuming other than 20-200 or so.

Axiom urges me to get 2 x EP600 subwoofers @ 600 Watts each. Trouble with this little equation is... THAT IS A FRICKING $3,500 FOR TWO SUBS!!!! Hello!!! ;-))
