Polk Audio RTi A1 Bookshelf Speaker Pair

• Treat yourself to detailed, accurate sound with Polk's compact RTi A1 bookshelf speakers.
• They feature Polk's exclusive Dynamic Balance® drivers for smooth accurate response.
• Plus the woofers and tweeters undergo careful laser testing to help identify and eliminate unwanted resonances that can hinder a speaker's performance.

• The asymmetric cabinet helps fight vibration for clearer sound.
• The RTi A1's newly designed asymmetric cabinets help them deliver rich, clear sound by combating vibration and increasing rigidity.
• You'll enjoy remarkably clean mids and highs for a well-defined soundstage, along with tight bass.
• Plus, the cabinet's curved edges give the speaker a polished look, enhanced by a real wood veneer finish.

• The RTi A1s do a great job with stereo music on their own, or you can team them with a powered subwoofer for even better bass.
• Or use two pairs as your home theater's front and surround speakers for dynamic, detailed movie sound.
• For larger rooms, the RTi A1s work perfectly as surrounds in combination with RTi tower front speakers.

Driver Technology

Dynamic Balance:

•  Dynamic Balance is a proprietary Polk Audio technology using laser imaging to determine what combination of speaker materials create the least amount of resonance.
• Eliminating resonance in speakers results in a wide, smooth response and low distortion.

Polymer Composite Woofers: 

• Each speaker features a 5-1/4" polymer composite woofer for smooth wide-range response with low distortion.
• For high performance durability, each woofer uses a butyl rubber surround.

Silk/Polymer Tweeters: 

• Each speaker has a 1" silk/polymer dome tweeter that provides clear, detailed highs.
• Each tweeter features mylar bypass capacitors in the crossovers to extend high frequency response and improve detail and transparency.
• Each tweeter features low viscosity ferro-fluid cooling with a heat sink on the Neodymium magnet for superior heat dissipation, power handling and reliability.

Frequency Response: 

• The overall frequency response is 50Hz-27kHz and the -3dB frequency response is 60-26kHz.

Enclosure Design

Damped Asymmetric Hex Laminate (DAHLI) Cabinet Design: 

• All-MDF construction with massive asymmetric cabinet bracing ensures a resonance-free enclosure for accurate sound.
• The asymmetric design is made from a 6-layer laminate with 5 viscous layers to create the optimal shear damping (OSD) system.
• The elegant styling aside, curved cabinets not only result in a stronger, more rigid and acoustically inert enclosure, but the curved walls also produce less audible coloration from panel resonances.

Power Port Venting System: 

• Each speaker has a rear-firing Power Port venting system built into its back plate for precise deep bass response.
• This venting system allows air velocity to slow gradually, vastly reducing air turbulence, and delivering greater bass efficiency than conventional ports.

Acoustic Resonance Control (ARC): 

• Internal cabinet resonance can impart a "thick" character to voices.
• Polk's patented Acoustic Resonance Control port system overcomes this problem.
• In addition to the Power Port venting system, each speaker has a front-firing port that is tuned to suppress the internal cabinet resonance, resulting in smooth, natural midrange reproduction.

Anti-Diffraction Grilles: 

• The floating anti-diffraction grilles minimize grille diffraction for spacious, 3-dimensional imaging.

Connections

Dual 5-Way Binding Posts:

• Each speaker has two sets of gold-plated 5-way binding posts connected by gold-plated jumpers.
• Using the dual 5-way binding posts, you can bi-amp or bi-wire the speakers.

Mounting Options

Wall Mounting: 

• The Power Port back plate on each speaker has a keyhole slot, allowing the speaker to be mounted on the wall using the supplied 2-1/2" wood screws.

Magnetically Shielded: 

• The speakers are magnetically shielded, allowing you to place them near your television without distorting the picture.
