I currently have a mismatched 6.1 system. I not sure any of the model numbers. I have 2 JBL bookshelves, a KLH center, and 3 Kenwood sats. For around $275(w/ free shipping) I can get... (1)SONY CENTER (2)SONY 8" BOOKSHELVES (3)SONY 5 1/4" BOOKSHELVES I would use these with my Kenwood 6070 receiver and my Sony WM40 sub. I would use these for about 80% movies and 20% music. Are these speakers any good or are they garbage. Are there any other speakers I could get in this price range or for a little more. Any help would be greatly appericated.
