I'm looking to replace a couple of JBL N32 floor standing speakers with some bookshelf speakers. I've been told it'd be a good idea to match the book shelves to my JBL S Center II center channel. Anyone have any info on what would be a good JBL book shelf model to pair with my S Center II? Currently running a 5.1 system in a small living room. 46 inch Samsung LED wall mounted with Center Channel under. Thanks in advance.
