From the incorporation of our latest Dynamic Balance Cone drivers and 1 inch tweeters to an elegant restyling of the cabinets in keeping with the latest styles. The floor standing models feature "Power Port Plus" an enhancement of Polk's patented Power Port technology. As you would expect from this highly popular line, the performance is classic Polk.

    The Polk RTi A3s feature Polk's exclusive Dynamic Balance® drivers for smooth accurate response. The woofers and tweeters undergo careful laser testing to help identify and eliminate unwanted resonances that can hinder a speaker's performance.

    Thoughtful cabinet design

    The RTi A3 sports a newly designed asymmetric cabinet that helps deliver rich, clear sound by combating vibration and increasing rigidity. You'll enjoy remarkably clean mids and highs for a well-defined soundstage, along with tight bass. Plus, the cabinet's curved edges give the speaker a polished look, enhanced by a real wood veneer finish.

    Great for home theater or stereo music setups

    The RTi A3s do a great job with stereo music on their own, but you can team them with a powered subwoofer for even better bass. Or use two pairs as your home theater's front and surround speakers for dynamic, detailed movie sound. For larger rooms, the RTi A3s work perfectly as surrounds in combination with RTi tower front speakers.

    Recommended center channel speaker: Polk CSi A6.

    Recommended surround speakers: Polk RTi A3.
