High Performance, Compact Size, Surprising Price
Don't settle for flat sound from your flat panel TV, and don't miss out on the excitement of digital surround-sound in your shows, movies and games. Great surround-sound doesn't have to take up a lot of space or cost all that much. The payback is family fun and entertainment excitement. Don't miss out.
TL1 Features:
- The silk dome tweeter delivers a classic, clear, detailed Polk performance, with pinpoint imaging and smooth highs that are never tiring.
- Time Lens® technology aligns the acoustic centers of the tweeter and mid-bass driver on the same spatial plane for superior imaging, while an acoustic lens incorporated in the grille smoothes the tweeter's frequency response.
- The unique curved enclosure design employs non-parallel surfaces to strengthen the acoustically inert enclosure and deliver less audible coloration from internal surface resonances.
- Because of its Extended Linear Motion motor structure, the moving parts of the drivers used in the Blackstone TL Series can move farther, more smoothly, in a smaller space than any other speaker driver in an enclosure this size, achieving the kind of dynamic response (clarity, volume) you'd expect from much larger speakers.
- An aperiodic-tuned rear-firing bass port combines the extension of a ported enclosure with the smoother low-end of an acoustic suspension enclosure, controlling port air flow for the kind of big bass response, and perfect speaker-subwoofer blending, you'd never expect from a loudspeaker you can hold in the palm of your hand.
- The Blackstone aerated polypropylene cone is lightweight, but stiff and strong, with longer linear excursion capabilities in a limited compact enclosure space, so it plays louder with less distortion.
- A super-small long-throw mid-bass driver, tuned with our patented Dynamic Balance® technology, delivers astonishingly smooth, flat frequency response, superior transparency and detail, and the surprising ability to play really, really loud for such a small speaker.
- 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.
- Hi-Gloss "Blackstone" finish, a durable, deep automotive-strength finish that matches today's most stylish flat-panel TVs and furniture.
- Compact means go-anywhere for Blackstone TL: on shelves, on the wall, on stands. Built-in keyhole slots and threaded inserts (that fit virtually any brackets) give you multiple mounting options.
- Gold-plated, professional-style 5-way binding posts, for the most secure connection options.
- All models in the Blackstone TL Series are available in convenient, professionally matched 5-packs for instant home theater solutions in any room. There are two complete systems available that include a subwoofer; everything you need for an explosive, compact, easy-to-connect home theater system. Plus, you can use individually-available satellites to expand your systems to accommodate 6.1, 7.1 and beyond.

At home on a stand, wall or bookshelf, the versatile 685 S2 is ideal for stereo and home theatre uses in most rooms. And performance is enhanced with the addition of a Decoupled Double Dome tweeter.
The Decoupled Double Dome tweeter found in the 685 S2, and the rest of the new 600 Series, is technology taken straight from our award-winning CM10 speaker. A dual-layer design combines a thin aluminium dome for lightness and a thicker aluminium ring for rigidity - the result is absolutely stunning, with far greater clarity in the audible spectrum.
The tweeter is also decoupled from the main cabinet, kept physically separate in its own cavity with a ring of gel cushioning it from vibrations. This improves imaging and dispersion for a more natural, spacious treble.
As well as a decoupled, double dome aluminium tweeter, the two-way 685 S2 features a full-range 6.5-inch driver constructed from woven Kevlar and using Anti-Resonance Plug dustcaps, as seen in high-end Bowers & Wilkins speakers. The result is stunning audio quality from a highly versatile smaller speaker.

The M-1 has been engineered with the same design attributes and ethos as B&Wʼs larger ranges. Perhaps the most striking thing about the M-1 is the weight and strength of its curved aluminium cabinet. This is combined with a strong, glass-loaded ABS front baffle. Together they provide an excellent cabinet: the curved aluminium is stiff and the ABS offers excellent and appropriate damping characteristics.
The M-1ʼs drive units were developed by Bowers & Wilkins specifically for the design. The metal dome tweeter benefits from refinements developed for the new B&W 800 Series and includes Nautilus™ tube loading and neodymium magnets. The glass fibre bass/midrange coneʼs ability to absorb standing waves has been further enhanced by the inclusion of five strategically placed resin filled slots that further minimise distortion.
The result of this detailed cabinet and drive unit engineering has allowed B&Wʼs engineers to borrow another feature from the new 800 Series and utilise the simplest of electronic equalisation in the M-1ʼs crossover. Each of the drive units is fed by only a single, carefully selected component. This approach to crossover design, although painstaking as it relies on optimising all of the physical components in a design, is crucial in achieving its aim of neither adding to nor subtracting from the original signal.
The M-1 is available in three colour options - black, white and silver, each with chromium plated stem and table base.
