Polk Audio RTI A5 Floorstanding Speaker (Single, Black)

Innovative design the RTI A5 features the latest generation of dynamic balance polymer composite drivers for smooth wide–range response with low distortion. The RTI A5 uses two long–throw mid–woofers combined with power port to deliver deep, high–impacdsxat bass with speed and accuracy. All–mdf construction all–mdf construction and asymmetric cabinet design cabinet resonance can ruin the sound of an otherwise well–designed speaker. You don't want to hear your speaker cabinets humming along with the music, you want to hear the uncolored sound launched by the drivers and tweeters. We take special pains to make sure that Polk speaker cabinets are resonance–free. Our new RTI a Series loudspeakers employ an asymmetric design composed of a six–layer laminate, the process for which was specifically developed for Polk, and which controls resonance and increases cabinet rigidty.

Power port bass Venting for superior clean, low distortion bass that you can really feel.Power port vastly reduces chuffing or port Noise and provides deeper, more powerful, lower distortion bass than could be realized with conventional ported or sealed designs of comparable size. Magnetic shielding for safe placement near video sources. Mylar bypass capacitors in the crossovers extend high frequency response and improve detail and transparency. Neodymium magnet, low–viscosity ferro–fluid cooling, and a heat sink on the back of the magnet, create better power handling and reliability.
