Polk Audio TL-2 speakers (pair) surround speakers

TL2 SATELLITE Features:

• 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 our Dynamic
  Balance® technology, deliver a flatter frequency response with
  transparency, sharp detail, and the ability to play loud with no strain
  at all.



• 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.



• 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 smooths 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.



• 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.



• 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.
