Thinking of upgrading speakings in a 2x12 cab. I'm mainly using it for my Germino LV55. I already have the standard 25 watt greenbacks and was wondering if I'd notice that much difference given the cost. I figure they would sound good with some of my other amps that are more modern/hardrock sounding since they are in the new 5150 cabs. Would this be a waste of money? Aside from the volume drop (a good thing) would this really be that big of a difference?
