never one for controversy, but here goes... IME, 15" speakers just never cut it. they were always too slow and unresponsive for slap, and seemed unable to cut thru a dense mix. also, the fact that they dont really go no lower in frequency than most 10" loaded cabs or 12" loaded cabs, seems like they'd be phased out for a better performing size. and tho alot of gents say, they're best in rock, seems like i'm only seeing walls of 6x10 or 8x10's, behind all the sid vicious like pbass pummelin' rockers. anyone else feel this way? and if not, enlighten me O' TB Amps Knowledgable & Faithful!
