Listen to clear, realistic sounds through incredible audio
Polk knows for the most realistic home theatre audio, it’s best to place a centre channel speaker underneath a TV. This speaker, finished in a stunning black stain, was designed to take full advantage of sub-screen placement, giving you smooth, natural sound. Instead of fiddling around to find the right audio angle this speaker automatically tilts itself in your listening direction, preventing frustration and maximizing entertainment enjoyment. What’s more, Polk speakers are built to last a lifetime. This piece, like all the others, has passed extensive testing and was built with premium materials and manufacturing techniques. Most importantly, it delivers clear, realistic sound, making all your entertainment – from music to movies and beyond – sound amazing.

Enjoy an exceptional experience through Polk’s special technology
There is so much more to this speaker than just a beautiful body and a loud performance. Polk’s Dynamic Balance® technology works to produce smooth, natural sound. Its silk and polymer dome tweeter delivers clear, detailed high notes and realistic vocal reproduction even at high volume. Meanwhile, a rear-firing flared bass port minimizes unwanted noise and effortlessly blends low sounds with the speaker’s overall range, creating the wide dynamics you want in a centre channel speaker. Together, all these special components consistently deliver incredible audio.

Great on its own or as part of the TSx Series set (sold separately)
As incredible as this speaker is on its own, imagine it working together with additional speakers from the same family. Part of Polk’s TSx Series, this piece is timbre-matched with other pieces (sold separately), and designed with the same components throughout. This achieves seamless speaker-to-speaker blending when they’re all working together to provide you with an incredible experience. The TSx Series features a high-efficiency design, allowing the pieces to work well with practically any other electronics – even modestly-powered amplifiers or receivers. Either on its own or as part of a group, this speaker delivers a natural, realistic performance.
