I am in the process of evaulating options for upgrading to a better bass amp unit. I have tried a few Hartke cabs and really liked their sound. Have any of you tried the new 2100/2200 series cabs? What were your impressions of the sound? I am very surprised by the Hartke cabs I have tried so far. The bass response exceeds what I would expect from even their smaller cabs. I am toying with the idea of my new rig being a Hartke 3500 series head with a 2200 cab. Comments?
