Polk Audio's R30 floorstanding speaker furthers the company's tradition of using high-quality materials and excellent engineering to deliver exceptional sound and exceptional value. Its slim, tower design conserves floor space (occupying less than 1 square foot), and it's ideal for both movies and music. The speaker is sold individually, so be sure to pick up 2 for a stereo arrangement, 4 four front and rear left/right, etc. The speaker features Polk's exclusive Dynamic Balance drivers for wide frequency response and low distortion in both its .75-inch dome tweeter and its single 6.5-inch cone woofer.

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," three-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."

Magnetically shielded for safe placement near TVs and computer monitors, the speaker offers convenient, high-quality 5-way binding post terminals to accommodate several wire hook-up options. All Polk's R Series loudspeakers are perfect for building starter surround systems or for small-room or multi-room settings. With the addition of a PSW Series powered subwoofer, you can build an impressive home theater on a limited budget.
