The Handiest of Bookshelf Loudspeakers
Solidly built for solid performance, the R150 can be used to build a small system, or used to add speakers to any other system. The R 150 comes with a rear-firing bass port that adds surprising low end.
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.
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.
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.
