Enjoy rich, dynamic sound

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.

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.
