POLK AUDIO RTiA 7 CHERRY

POLK AUDIO RTiA 7 BLACK

RTiA Series speakers are designed for clean, accurate sound - the proprietary curved enclosure design creates the optimal shear damping for a more rigid, acoustically inert enclosure and minimal cabinet resonance. These delicately curved enclosures are topped with a layer of beautifully finished real wood, are acoustically inert and internally braced to produce uncolored, resonant-free sound.

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.

POLK AUDIO RTiA 7 FEATURE

Highlight:

  • Classic Polk Audio sound quality in a floorstanding speaker
  • Custom butyl rubber surrounds and anti-diffraction grilles produce a lifetime of reliable sound
  • Polished hardwood veneer cabinet finishes with black or cherry trims

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.
