Polk Audio TL250 Compact Home Theater Audio System, 5 Pack

The Polk Audio TL250 is a 5-piece surround-sound system that presents high performance in a compact package that works with or without an additional subwoofer. These little loudspeakers feature Polk's patented PowerPort bass venting system, for unheard of deep bass response and superior, natural subwoofer blending. Build a professional quality extended multi-channel sound system by adding additional, timbre-matched TL2 Speakers (go from 5.1 to 6.1, 7.1 and beyond). The 5-piece system includes a center channel speaker, front speakers and surround speakers.

The silk dome tweeter delivers a classic, clear, detailed Polk performance, with pinpoint imaging and smooth highs that are never tiring. Injection molded composite cones, tuned with Polk's Dynamic Balance technology, deliver a flatter frequency response with transparency, sharp detail and the ability to play loud with no strain at all. The extra-rigid steel plates reinforce the beautiful curves of the TL2 speakers, resulting in acoustically inert enclosures free from internal resonances and any audible coloration, for more lifelike audio detail.

The 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.

The PowerPort bass venting is Polk's patented design for smoothly transitioning the air flow from the port into your listening area, eliminating turbulence and distortion, for bigger, more efficient, deep bass impact. Adding a PowerPort to a compact loudspeaker allows it to achieve deeper bass, for better blending with your subwoofer, than ever before. The Polk's proprietary, patented Dynamic Balance technology allows Polk's engineers to design out distortion-causing driver and system resonances, so you only hear the good sounds. The built-in keyhole slots and threaded inserts (that fit virtually any brackets) give you multiple mounting options. The gold-plated, professional-style 5-way binding posts, for the most secure connection options.
