Last weekend I found a few of JBLs new Studio and Northridge speakers on sale for half price..actually just the floorstanders were on sale. I bought them to re-sell but now I am considering keeping them because I like my S26s so much. So I have all of the following speakers and I am not sure which ones I should keep. (2) pair of JBL N38 (1) pair of JBL ND310 (1) pair of JBL S312 I know for sure I would want the S312s as mains and I could go buy an S-center on Ebay for about $140. Now I am pretty confindent that the N and S series will match well enough to use the S up front and the N in the rear. The question I have is which would sound better..4 N38s in the rear for a 7.1 set-up or 2 ND310s in the rear for a 5.1 set-up? Basically more smaller speakers or less bigger speakers?..is the question. Mains: 12" bass, 4" mid, 1" titanium tweeter 92db efficient 35hz-20khz Crossover; 750hz, 3000hz Center: (2) 5 1/4 bass, 4" mid, 1" titanium tweeter 91db efficient 75hz-20khz Crossover: 800hz, 3200hz N38(have 4 of them): 8" bass, 4" mid, 3/4" titanium tweeter 90dbs efficient 45Hz-20Khz Crossover: 1000hz, 5000hz ND310(have 2): (2)10" basses, 4" mid, 3/4" titanium tweeter 91dbs efficient 37Hz-20Khz Crossover: 1000Hz, 5000Hz Maybe I should keep them all and wait for a bigger place to live and more surround formats to come out that require more speakers?
