Dynamic Balance®

Proprietary Polk Audio technology eliminates distortion-causing driver and system resonances, so all you hear is high-quality sound.

Cascade Tapered Crossover

Innovative crossover eliminates comb filtering and beaming for higher quality audio and a more expansive sound stage.

Trapezoidal Shaped Cabinets

The trapezoidal shaped cabinets aim the drivers and tweeters in opposing directions to produce a more realistically diffuse wavefront and wide, lifelike imaging of surround sound.

Bipole / Dipole Circuitry

With the flip of a switch, our dipole/bipole circuitry changes the soundfield from direct to indirect radiation patterns enabling you to place the surround speaker beside or behind you depending on your listening room setup.

Acoustic Resonance Control®

Patented Acoustic Resonance Control® (ARC) technology suppresses distortion-causing cabinet resonance to ensure clear and natural sound.

Klippel Motor Optimisation

Laser measurement technology ensures a smooth excursion path at both ends of the volume spectrum for uniform performance at all volumes.

Anti-Diffraction Grille

Computer modelled for a precision fit and enhanced good looks - and made to minimise sonic interference.

Dual Gold Plated 5-Way Binding Posts

Perfect for easy setup, they ensure the most direct, efficient, and loss-less connection possible.

Timbre-Matching

Compatible with the entire Polk Audio RTi Series for seamless blending from speaker to speaker in multi-channel systems.
