would 2x12 avatar speakers be loud enough for a loud modern rock band? id be going against a 4x12 guitar half stack powered with 100 watts. ive been thinking about getting 2 1x12 cabs for ultra portability. maybe 1x12 and 2x10's, or a 2x12 cab and 2x10's. what do you guys think? i played thru some 12 inchers today and really dig the lows they put out. warm and thumpy but so much more musical then 15's.
