A big part of the TL3's incredible sound is the 3/4" Ring Radiator tweeter. Found in Polk's flagship speakers, this sophisticated tweeter reproduces transparent, natural highs. The dual 3-1/4" aerated polypropylene woofers are lightweight, but also stiff and strong, allowing the cones to move more freely in the baffle. It means you can play your music and movies loud without hearing any distortion. Polk's Extended Linear Motion voice coil helps make the cone movement even more efficient to further cut down on distortion and extend the speaker's dynamic range. This increased efficiency is the key to the TL3's big speaker sound.
