Three high performance bi-laminate drivers tuned with our Dynamic Balance technology reveal the length and breadth of your favorite music or movie audio. A superior state-of-the-art silk/polymer dome tweeter keeps highs detailed and clear, with no listening fatigue, even at lifelike volume levels. Combined in a non-resonant enclosure (that looks like a million bucks) with a critically tuned flared bass venting port system, for astonishingly well-blended deep bass effects, and you have a floor standing loudspeaker that pairs audiophile performance, good looks, and reasonable price. A Polk classic!
