POLK AUDIO R300 (Black)
High performance Two-way floor-standing loudspeaker

The R300 is like the Darth Vader of "entry-level" high performance loudspeakers. (Can I say that without getting sued?) That’s not to say that the R300 is evil, or even bad, at all. It’s just... imposing. Tall, black, slender, commanding. You can definitely see it coming through that airlock door and taking charge. “I’m the father of good value audio, Luke!” Ok, maybe not. I’m working as hard as I can. Build a slam-bang audio system by using the big R300 floorstanding loudspeaker as your left and right front stage. Use the matching R150 bookshelf speakers as your rear surrounds. Slip a CSR center speaker in there, and you have some tremendous bang—big effects, superior detail, wide response—for your buck. Come over to the dark side; we have great audio!
    
Big Power, Little Cost

The beautiful, high quality R300 is a great introduction to the wonders of full range dynamic floorstanding speaker sound. The silk dome tweeter & polymer composite driver components reveal lifelike audio, with realistic imaging and detail and a broad soundstage. A tuned rear-firing bass port smooths blending, for serious low end with absolutely no performance-robbing resonances.
R300 Features:

Unlike other speakers in this price range, R/T/M Series enclosures are constructed of solid, extensively braced MDF. This virtually eliminates internal resonances and damps energy-stealing vibrations, for more efficient operation and more transparent sound.

This slim tower design conserves floor space, occupying less than one square foot.

Polk’s proprietary, patented Dynamic Balance® technology allows our engineers to design out distortion-causing driver and system resonances, so you only hear the good sounds.

Unlike horns or metal domes, silk dome tweeters deliver clear and detailed highs, without fatigue, even at high volume.

Durable, efficient, and tuned with our Dynamic Balance process, polymer composite cones produce smooth, natural sound.

Acoustically-inert stamped driver baskets are strong and vibration-free, and durable butyl rubber surrounds deliver a lifetime of high performance.

R/T/M Series models all feature professionally designed, speaker-specific bass porting, for highly efficient deep bass response that adds thrilling realism to your sound.

An “open architecture” anti-diffraction grille design, and acoustically inert speaker grille, will never get in the way of your sound.

Our high efficiency design results in sound that’s spacious and clear, warm and realistic, when combined with practically any electronics, even the most modestly-powered amplifer or receiver.

All Polk loudspeakers are timbre-matched within their series, designed with the same components throughout, to achieve seamless speaker-to-speaker blending effects in multi-channel systems.

Dual gold-plated, professional-style 5-way binding posts, for the most secure connection options.

All models in the R/T/M Series are magnetically shielded, and engineered to be safe when placed near sensitive AV equipment like monitors or TVs.

Floorstanding R/T/M Series models feature interchangable non-skid leveling feet or carpet spikes, for stability on any type of floor. More stability equals more efficiency, less energy wasted, and better performance.

All Polk products are made using the best materials and the most advanced manufacturing techniques. They pass the industry’s most exhaustive quality tests, including drop testing, extreme signal response and UV & salt exposure testing. Polk loudspeakers are built to perform for a lifetime.
