Product Description When it's time for serious music or home theater, it's time for Polk Audio's R50 floorstanding speaker, which is built to deliver years of high-quality, full-range listening. The R50 furthers the company's tradition of using high-quality materials and excellent engineering in service of exceptional sound and exceptional value. The R50's slim, tower design conserves floor space (occupying less than 1 square foot), and the speaker is ideal for both movies and music. It's sold individually, so be sure to pick up 2 for a stereo arrangement, 4 four front and rear left/right home theater use. Other Polk Audio R-series speakers would provide perfect timbral matching for use as surround speakers, but keep in mind that most music-only surround mixes such as those heard on DVD-Audio and multichannel SACD are intended for full-range surround speakers.

The R50 features Polk's exclusive Dynamic Balance drivers for wide frequency response and low distortion in both its .75-inch dome tweeter and its dual 6.5-inch cone woofers. Dynamic Balance started with laser interferometry research done in partnership with the Johns Hopkins University. Full-field laser-imaging research allowed Polk to view a driver's entire vibrating surface, revealing the resonance that develops on speaker cones as they move. That resonance is the root cause of frequency-response distortions. Knowing this helped Polk engineers find the right combination of materials, geometry, and construction techniques to tune out the offending resonance. The resulting Dynamic Balance technology produces flat frequency response, sharp detail, sonic transparency, and a speaker's ability to play dynamic programs at life-like levels without a hint of strain.

All woofers and tweeters in Polk home speakers feature Dynamic Balance technology, giving them a shared sonic signature for coherent, seamless sound even when you mix models in configuring your home theater. The drivers' wide dispersion means they project sound over a wide area, so every listener in a room will hear open, "box-less," 3-dimensional sound.

A front-firing bass port confers high efficiency and powerful bass response. The speaker's arched grille eliminates grille interference with the port output, lowering turbulence and distortion while giving the speaker a cool look. Supplied carpet spikes ensure mechanical stability on carpeted floors for precise bass output and superior "imaging." The speaker is magnetically shielded to permit distortion-free placement near TVs and computer monitors.

Convenient, 5-way binding posts provide an array of secure hook-up options, and the speaker is covered by Polk's standard, non-transferable 5-year warranty.
