Enjoy crisp sound with this Polk Audio CSi A4 center-channel speaker that features two 5-1/4" polymer composite midranges and a 1" silk/polymer dome tweeter. Klippel Optimization ensures efficient operation at several volume levels.
I already had the two fronts and the rear channel speakers. I needed the center channel, which is what I purchased. Now the voice matched speakers sound awesome with both movies and SACD music. I didn't think having voice matched speakers would make that much of a difference but I was definitely blown away.
What's great about it: sounds great, looks good
What's not so great: doesn't physically match my older towers they changed the design.
