Hello, I've been using an Ampeg SVT3Pro with an Ampeg SVT410HLF, the combination sounded good, but it just seemed to me a little underpowered. Recently, I picked up an SVT6Pro Amp from a fellow TB'er, which defenetely fills in the 410HLF cabinet nicely!! However, when I turn my amp past half volume, I get some speaker flutter as if the amp is about to blow a speaker. (maybe I already blew the speakers?... but sounds fine if I turn it down a little) Anyway, I suppose I should probably find a cabinet that is closer in wattage to the SVT6Pro amp... but here is my dilemma... I really don't want to get anything that is heavier or larger than the 410 cabinet 'cause it won't fit in my car (plus I want to save my back). These are the specs in question: SVT3Pro = 450W @ 4 Ohms SVT6Pro = 1100W @ 4 Ohms SVT410HLF = 500W @ 4 Ohms I'm looking at Mesa and Harke, which have some cabinets close in dimensions, but are 600W (it's not clear to me if they are 4 or 8 ohms). Can anyone give me some recommendations? The key is to keep the cabinet close in dimensions as what I have now, but give a little more room for volume on my SVT6Pro, while retaining a warm tone (that's mainly why I like the Ampeg stuff) Thanks.
