The new RTiA Series incorporates Polk’s latest Dynamic Balance® cone drivers and 1″ tweeters and elegantly redesigned cabinets that reflect the latest styles.
As you can expect from this highly popular line, the performance is classic Polk.

Damped Asymmetric Hex Laminate Isolation (DAHLI) Cabinet Design for clean, accurate sound. The asymmetric design is made from a 6-layer laminate with 5 viscous layers to create the optimal shear damping (OSD) system, the process for which was specifically developed for Polk. Their elegant styling aside, creating curved cabinets not only results in a stronger, more rigid and acoustically insert enclosure, but the curved walls also produce less audible coloration from panel resonances.

All 2007 RTiA, CSi And F/Xi Models Feature The Latest Generation Dynamic Balance Drivers And Tweeters. The bass/midrange drivers used throughout the RTi range employ polymer/mineral composite cones.

1″ Tweeter Is A Silk/Polymer Composite Dome for smoother response and better detail.

A Neodymium Magnet, Low-Viscosity Ferro-Fluid Cooling, and a heat sink on the back of the magnet, create better power handling and reliability.

Magnetically Shielded to allow safe placement next to televisions or video monitors.
