I am currently running a H/K 630 reciever with JBL E90's up front and I was wondering about the placement of the rest of my speakers. I have some JBL S38's and some Infinity entra three's. which would make better side and rear speakers? I dont know how I would mount the S38's up high in the rear,(any suggestions?) or should I place them on a shelf to the side of me and put the infinity's in the rear? will this cause any problems not having the side or rear speakers placed above my head? this will be in the basement of a house about 20'L X 12' W X 7' H. All suggestion will be greatly appreciated.
P.S. I was also wondering about a quality center channel for this system. JBL and Infinity are obvious choices but are there any others I should consider that would match up well? I dont really want to spend much more then $250.00
