Speaker has high performance silk/polymer dome tweeters anchor the action with clear and detailed highs, even at high volume, and more realistic vocal reproduction. Rear-firing flared bass port minimizes port noise (chuffing) and smoothly blends low frequency response with the speaker’s overall dynamics, for the kind of wide dynamics you want in a center channel speaker. All Polk loudspeakers are timbre-matched within their series, designed with the same components throughout, to achieve seamless speaker-to-speaker blending effects in multi-channel systems.
