So you got these Axiom bucks from demoing your system to someone and then they mentioned your name when they ordered their own Axiom's? Very cool.
As someone faced with that same decision recently, I upgraded from a C- grade subwoofer for a nice SVS (really close between SVS and EP500), and am glad I did. Made a big difference in the balance of my system. A huge improvement when it comes to movies, as expected. But also a pretty nice improvement for music as well. Didn't know what I was missing!
However, I'm still going to eventually upgrade to M60/M80's.
