I have 4 yamaha NS-333 speakers and am planning to use them as mains and surround speakers, then buy a center speaker that would match them and use them for my bedroom home theater setup. The matching center speaker for them would be the Yamaha NS-C444 but I haven't seen any available anymore. Can someone point me in the right direction or maybe recommend an alternative center speaker that would match my NS-333s. I was thinking about the Polk TSi CS10 center. Would this be a good match or would I be better off trying to find the Yamaha NS-C444? Thanks
