The silk dome tweeter delivers classic, clear, detailed Polk performance, with pinpoint imaging and smooth highs that are never tiring. 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.
