You might wan't to check out some British speakers like some of the older Mission 700 series. They were designed to be placed up against a wall. Maybe a couple of the Castle models that are currently on sale might work as well. They can also be placed near a wall. They say the build quality is excellent on the Castle's. I believe they make some of the cabinets for Proac also.
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.
