Benefits of Polk Audio RTiA1 Bookshelf Speaker (Pair)
Polk Audio’s Dynamic Balance Technology
The RTiA1 bookshelf speaker drivers feature Polk Audio’s proprietary, patented Dynamic Balance technology. This new-age design reduces unwanted distortion and system resonances to deliver superior and detailed sound reproduction.
Rigid 6-layer DAHLI speaker enclosure design
The proprietary curved, 6-layer DAHLI enclosure design of the Polk Audio RTiA1 bookshelf speaker creates the optimal shear damping for a rigid and acoustically inert enclosure with minimal cabinet resonances. The RTiA1 speakers cabinets are designed for clean, accurate, and powerful sound even from a compact enclosure.
Incredible accurate laser measurement technology
Polk Audio’s Klippel motor optimisation technology uses laser measurement to ensure a smooth excursion path at either end of the volume spectrum. The result is a balanced and uniform performance at both low and high decibels.
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
Patented Acoustic Resonance Control® (ARC) technology suppresses cabinet resonance that causes distortion to ensure clear and natural sound. The improved and innovative crossover eliminates comb filtering and beaming to deliver higher quality audio and an immersive soundscape.
