System has silk dome tweeter which delivers 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.
