I don't have experience with the sub, but from the ton of reading I've done on Axioms, their subwoofers aren't very good values untill you hit the 500 and 600. Below that, you're better off going Hsu or SVS. At the $650 pricepoint, I think I'd rather have a Hsu STF-3. Twelve inches of subwoofering goodness, a highly linear 300W amp, and just plain ol' non-flashy goodness. Compare that to the Axiom 200W MAX amp. 300W RMS is a lot more power.
