Amazon.com Product Description
Polk's 125-watt RTi4 bookshelf loudspeaker offers high output in a real wood enclosure for performance sound and great looks. The acoustically inert .75-inch MDF cabinet has asymmetric bracing ensuring resonance-free enclosures for clean and accurate sound. Floating anti-diffraction grilles lift off the baffle area, minimizing grille-edge reflections for clearer sound and more open imaging. And that's just the cabinet features.
Midrange bass response is tighter, punchier, and more accurate thanks to a 5.25-inch polymer composite Dynamic Balance drivers. Bass is further enhanced because of Polk's Power Port venting technology. The design consists of a cone at the mouth of the port and the space in between the enclosure and the plate. The cone promotes laminar (smooth) airflow and the ever-increasing cross-sectional area of the space mimics a very long flared port to vastly reduce air turbulence.
Clear, detailed highs are courtesy of the 1-inch silk/polymer dome tweeter with a neodymium magnet and heat-sinked for superior heat dissipation, power handling, and reliability. Dynamic Balance technology produces flat frequency response, sharp detail, transparency and an ability to play program material with wide dynamic range at life-like volume levels without a hint of strain.
Mylar bypass capacitors are used in the crossovers, which extends high frequency response and further improves detail and transparency. Dual, five-way binding post connectors (with wide holes for large-gauge bare wire connections) allow for secure hook-ups, as well as bi-wiring and bi-amping flexibility for more advanced set ups.
The RTi4 is timbre-matched to fit into any Polk Audio home theater or multi-channel music system for a more realistic, more seamless surround sound environment. Plus, the speaker is magnetically shielded for safe placement on or near TVs and video monitors with no risk of distortion.
