Polk Audio Blackstone TL3 Series Bookshelf Speakers

• This motor structure design, incorporated in the 3 1/4" mid-bass driver, flattens the BL curve over a widerrange of the driver’s excursion,reducing distortion and extending dynamic range.

• Design—non-parallel surfaces, combined with the extra-rigid steel plates, not only results in a stronger and acoustically inert enclosure, but also produces less audible coloration from internal surface resonances.

• A patented Polk technology, extends the low frequency mid-bass driverresponse as it decreases airturbulence, eliminates “port noise” and bass output losses up to 3 dB. 3/4" Ring Radiator Tweeter, used in our award-winning LSi and LCi Series speakers, delivers incredible accuracy and astonishing detail to beyond 30 kHz, even when listening off-axis.

• Is Polk’s patented solution to driver design that scientifically tunes materials to produce a flat frequency response, with sharp detail, transparency and the ability to play loud without strain.

• The same material used in our high-end freestanding speakers, is lightweight but stiff and strong, with longerlinear excursion capabilities to play louder with less distortion.

• Binding Posts accept 14 gauge cable and offer hookup versatility and secure connections. 

• Matches today’s most stylish flat panel TV’s.
