The most compact bookshelf speaker in the RTiA lineup sounds phenomenal. Its convenient size and solid performance make it a popular choice for both home theater or music systems. With a 5 1/4-inch Dynamic Balance midbass driver and a 1-inch Dynamic Balance dome tweeter, it produces the classic Polk sound in a small package.
Stereophile's Robert J. Reina loved the speaker saying, 'I enjoyed every minute I spent with the RTiA1. The speaker's greatest strengths-the natural and detailed midrange, the excellent bass extension are unheard of at this size and price.' For his full review, click here.
The proprietary curved, 6-layer DAHLI enclosure design creates the optimal shear damping for a more rigid, acoustically inert enclosure and minimal cabinet resonances. RTiA1 cabinets are designed for clean, accurate sound.
Klippel motor optimization uses laser measurement technology to ensure a smooth excursion path at either end of the volume spectrum for uniform performance at both low and high volumes.
Polk's proprietary, patented Dynamic Balance technology allows our engineers to design out distortion-causing driver and system resonances, so you only hear the good sounds.
Durable, computer-modeled, injection-molded butyl rubber surrounds suppress unwanted cone resonances for a lifetime of reliable sound.
The RTiA Cascade Tapered Crossover eliminates the comb filtering and beaming, common to multi-driver speakers, which degrades the quality of the audio and collapses the soundstage.
PowerPort Plus bass venting is our patented design for smoothly transitioning the air flow from the port into your listening area, eliminating turbulence and distortion, for bigger, more musical, deep bass impact.
Patented Acoustic Resonance Control (ARC) technology suppresses cabinet resonance that causes distortion to ensure clear and natural sound.
Beautiful curved furniture-grade hardwood veneer cabinet finishes, with sleek trim accents in black or cherry.
Computer-modeled anti-diffraction grilles enhance the good looks while minimizing sonic interference.
All Polk loudspeakers are timbre-matched within their series, designed with the same components throughout, to achieve seamless speaker-to-speaker blending effects in multi-channel systems.
Dual gold-plated, professional-style 5-way binding posts, for the most secure connection options.
All Polk products are made using the best materials and the most advanced manufacturing techniques. They pass the industry's most exhaustive quality tests, including drop testing, extreme signal response and UV & salt exposure testing. Polk loudspeakers are built to perform for a lifetime.
