Speaker has silk dome tweeter 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 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.
