i just picked up a new eden 212xlt (4 ohm) cause the 210 was way not loud enough for my band. just for fun, i tried the ampeg svt3-pro with the same cabinet and bass. the ampeg sounded good, it just didn't seem as loud as the mesa. the mesa is 300@4 ohms and the ampeg is 450@4 ohms. maybe it's got something to do with the design. both are excellent companies and i'm not about to say that one is better than the other. just an observation on my part. anyone else notice this type of thing? i did tweek the ampeg and got a really good sound out of it, just not the power i thought i'd get.
