Polk Audio FXi A6 Surround Speakers

The Polk Audio FXi A6 incorporates Polk’s latest Dynamic Balance® Cone drivers, tweeters and elegantly redesigned cabinets that reflect the latest styles. The performance is classic Polk Audio®. The drivers used throughout the F/Xi series employ Dynamic Balance polymer/ mineral composite cones with rubber surrounds. Mylar bypass capacitors in the crossovers extend high frequency response and improve detail and transparency.

The Polk FXi A6 features a switch between dipole or bipole circuitry, this switch changes the sound field from direct to indirect radiation patterns. This feature enables you to place the surround speaker beside or behind you depending on your listening room setup.

The FXi’s have trapezoidal cabinet shapes that aim the drivers and tweeters in opposing directions to produce a more realistically diffuse wavefront and wide, lifelike imaging of surround sound. Keyhole slots make mounting a snap.

Damped Asymmetric Hex Laminate Isolation

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 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.
