I haven't been around this place in a LONG time so I'm sure this has been talked about quite a bit...sorry for any redundancy. After being a lifelong JBL guy I decided to give QSC a try and ordered a couple QSC kw152's and a single QSC kw181 sub. All I can say is I'm not sure I'll ever buy a powered JBL cabinate again! These speakers BLOW AWAY the comperable 1000 watt JBL PRX 615's (which I sold a few months ago because I wasn't happy with them) and the QSC kw sub is impressively tight and loud for such a small box. I can really hear the difference in warmth between the K series and the wood box of the KW series...the kw152's are VERY bassy for a 15" box (which is good for the current music we play these days) and love flexability of the inputs on the QSC amp. Highly recommend.
