Benefits of Polk Audio RTiA3 Bookshelf Speaker (Pair)
Dynamic Balance Technology drivers by Polk Audio
The RTiA3 bookshelf speaker drivers feature Polk Audio’s patented and proprietary Dynamic Balance technology. This innovative design reduces unwanted distortion and system resonances in the cabinet to deliver superior and detailed sound reproduction.
String 6-layer DAHLI speaker enclosure design
The RTiA3 bookshelf speakers cabinets are designed for clean, accurate, and powerful sound even from a compact enclosure. The proprietary curved, 6-layer DAHLI enclosure design of the Polk Audio RTiA3 bookshelf speaker creates the optimal shear damping for a rigid and acoustically inert enclosure with minimal cabinet resonances.
Design with accurate laser measurement technology
Polk Audio’s Klippel motor optimisation technology deploys laser measurement to ensure a smooth excursion path at either end of the volume spectrum. The final output is a balanced and uniform sonic performance at both low and high decibel levels.
PowerPort® Plus venting for impactful bass
Polk’s PowerPort® Plus bass venting is a patented design for smoothly transitioning the air flow from the port to the listening area. This eliminates turbulence and distortion, for bigger, more musical, impactful, and deep bass reproduction.
Acoustic Resonance Control® (ARC) & Cascade Tapered Crossover
The improved and innovative crossover eliminates comb filtering and beaming to deliver higher quality audio and an immersive soundscape. Polk Audio’s Patented Acoustic Resonance Control® (ARC) technology suppresses cabinet resonance that causes distortion to ensure clear and natural sound emanating from the RTiA3 bookshelf speaker.
Timbre-matched with Polk Audio RTiA series
In a surround system, the biggest hurdle is to ensure that the speakers are tonally similar. With this in mind, the RTiA3 bookshelf speakers are timbre-matched with Polk Audio RTi Series for seamless sound in multi-channel home theatre systems. Now you can easily custom-design your own surround sound package for music, movies, TV shows, and gaming sessions.
