Polk Audio RTI-A5 Tower Speaker Pair- Max. Power Handling Each Watts - 250 W Tower Speaker  (Black, 2.0 Channel)

Natural sound from slender tower speakers You can count on the polk rti a5 for clean, precise music and high-impact home theater. This slender tower speaker uses patented polk technologies for true-to-life sound, and its curved edges and real wood veneer finish give it a handsome, refined look. A high-tech approach to accurate sound This speaker's carefully designed drivers undergo laser testing to help identify and eliminate resonance points, ensuring smooth, accurate response. Its asymmetric cabinet helps it deliver rich, clear sound by combating vibration and increasing rigidity. Polk's exclusive powerport® technology reduces noisy air turbulence and increases low-frequency output. You'll enjoy clear highs, rich bass, and open, natural-sounding midrange.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: the speaker features two 6.5" polymer composite woofers. Two 6.5" woofers have the surface area of a single large woofer with the low mass and acceleration of small woofers, resulting in tighter, more accurate bass response. Each woofer uses a butyl rubber surround. Silk/polymer tweeter: the speaker has a single 1" silk/polymer dome tweeter that provides clear, detailed highs. The tweeter features mylar bypass capacitors in the crossovers to extend high frequency response and improve detail and transparency. The also tweeter features low viscosity ferro-fluid cooling with a heat sink on the neodymium magnet for superior heat dissipation, power handling and reliability. Magnetically shielded: the speakers are magnetically shielded, allowing you to place them near your television without distorting the picture. 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: the 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.
