First Time Post... Ok here is the deal.. I'm just about ready to make the big purchase (receiver, floor speakers, sub). For the receiver I'm picking up a B&K AVR307. For the sub I think im going with the RSW-12. Now here's what I cant decide.. should I go with the RF-7's or KLF-30's. I have heard both speakers and was equally impressed. Are there any drawbacks or advantages to either speaker? My music selection is pretty wide but mostly consists of Rock/Industrial/Metal. What do you think?
