APRAYMAS

Elevated Audio

The RTiA7 truly stands out. With two 7″ bass drivers, a 6.5″ midrange driver and a 1″ dome tweeter, this impressive floorstanding loudspeaker mixes stunning performance and classic beauty to rise above the competition.

Dynamic Balance

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

Power Port Plus

Patented bass venting design smoothly transitions air flow, eliminating turbulence and distortion, for deeper, more efficient bass impact.

Cascade Tapered Crossover

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

Klippel Motor Optimization

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

Timbre-Matching

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

ARC

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