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.
