Best used speakers around 500 for clasic rock


I'll be in the market soon for some used speakers that will sound good in my lingroom which is 13'6" x 15'6" They will be tied into a carver amp & CJ PV10. I listen to southern rock, clasic rock, blues & some jazz rock. The problem I have is that there is no other place except against the short wall with no room to come out & over unless I want to move the speakers out every time I listen to my system & even then there isn't much room to move out. I listen to alot of music I record myself in a "rock" concert setting so image & soundstage are very high priorities.

What about my placement concerns with any of these speakers? Am I tied into the Klipsch b/c of their preference of being in a corner? Exactly where my speakrs are located now?
I think the B&Ws come with removable foam plugs for the reflex ports in case they're in corners or against rear walls. Corner placement will kill imaging, but I expect you know this.
Can't argue a good point!! JBL's are well crafted, rocking boxes. Keep those six inch drivers leaves the big un's for the rest of us!!
