Polk to Unveil Blackstone® TL350 5.0 Satellite/Center System, Featuring Audiophile-Grade Technologies for Detailed Sonics

Top-of-the-Line Blackstone TL Model Rivals Systems Costing Thousands More

LAS VEGAS, NV, January 3, 2011 Polk Audio®, the Speaker Specialists®, will debut the Blackstone TL350 5.0-channel satellite/center speaker system at the 2011 Consumer Electronics Show, topping off the new Blackstone TL Series, a natural evolution of the company’s ground-breaking RM Series of surround sound speakers.

Infused with audiophile-grade technologies and components, the RM Series’ top-of-the-line Blackstone TL350 5-pack brings a truly sophisticated level of performance and sonic detail associated with systems that are many times the size and price.

The Blackstone TL350 is the best example yet of Polk Audio’s ability to deliver big speaker sound without the big speaker, said Polk Audio Line Manager Al Baron. By using many of the same driver elements found in Polk’s reference LSi series, our engineers created palm-of-the-hand sized speakers with performance that belies its size price tag.

Comprised of four TL3 satellite speakers and one TL3 center channel speaker, the Blackstone TL350 satellite/center channel system (SRP: $749.95) relies on advanced Time Lens Technology to align the acoustic centers of the tweeter and mid-bass drivers for superior imaging, while the acoustic lens incorporated in the grille smoothes the tweeter’s frequency response to achieve a balance not previously thought possible in small, satellite speakers. The 3/4-inch ring radiator tweeter is the same one used in Polk’s award-winning reference LSi and LCi series of audiophile speakers to deliver accuracy and detail to beyond 30kHz, even when listening off-axis.

An extended linear motion voice coil incorporated in the 3 1/4-inch mid-bass driver reduces distortion and extends dynamic range, thanks to several innovations developed by Polk Audio. The company’s patented Dynamic Balance® driver technology is mated with a 3 1/4-inch aerated polypropylene cone (APP) to produce a flat frequency response with sharp detail, transparency, and the ability to turn up the volume without creating strain. For improved mid-bass performance, the TL3 features Polk’s patented PowerPort® technology that decreases air turbulence, eliminating port noise and bass output losses up to 3dB.

Available in decorator-friendly Hi-Gloss Blackstone? black or white finishes, the Blackstone TL3 is housed in a strong, steel-reinforced curved enclosure designed to deliver sound free of cabinet vibrations and less audible coloration from internal surface resonances. Five-way, heavy-duty metal binding posts accept 14-gauge cables, offering hookup versatility and secure connections with other source components in a home theater system.

Adds Baron: The TL3 sub/sat system combined with one of our DSW Pro Wireless subs is the best way to enjoy true high-end sonics for less than $2,000. Without a doubt, it’s one of our most impressive achievements to date.

In late 2010, Polk delivered the Blackstone TL1 and TL2 Series models that further illustrate the company’s commitment to deliver high home theater performance in a compact system. Both models incorporate the TL3’s main technology attractions, including Time Lens technology, Polk’s Dynamic Balance driver technology, a curved enclosure design, and the trademark Hi-Gloss Blackstone finishes.

The TL2 distinguishes itself from the more compact TL1 with its use of Polk’s patented PowerPort technology and features 3/4-inch silk dome tweeters and 3 1/4-inch composite injection molded cones with Dynamic Balance driver technology, while the TL1 Series employ 1/2-inch silk dome tweeters, 2 1/2-inch long-throw drivers, and tuned satellite and center channel rear ports for superior blending with a subwoofer.

The TL2 is available in two models: The TL250 High Performance 5-Piece Surround System (SRP: $499.95) and the TL2600 5.1 Package with Powered Subwoofer (SRP: $749.95). The TL1 Series includes the TL150 High Performance 5 Piece Surround System (SRP: $399.95) and the TL1600 5.1 Package with Powered Subwoofer (SRP: $499.95).

The Blackstone TL350 5.0 satellite/center system will ship in March.
