I agree with the older Infinity's, Jbl 4311/L100 series and I would like to add one other if you like imaging - The older Snell speakers - E series and up! I have a pair of E/II's that I use without a subwoofer. I also own Infinity,JBL,Klipsch and Def Tech. Klipsch is also a good buy the heresy's will need some sub help. If you can get Klipsch Chourus or Forte's cheap - do it. Corner placement is not a requirement for all Klipsch speakers - Just for the KornerHorns, Klipschorns, and maybe the Belle's, all others can come out the corner.
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.
