im looking for a sub in the $300 range (maybe a lil more). all my speakers are infinity so, the infinity entra sub was a natural option. but at a lower price is the velodyne CHT8 which has very similar specs, but is $50 cheaper than the infinity. can i get some opinions? i know velodyne is highly reguarded most of the time. i guess i should mention that my main speakers are infinity studio monitor sm-255's. these have 15" woofers, 2 5.25" mids, and a .75" tweeter.
