You Want To Feel The Bass Most large floorstanding home theater speakers deliver good bass response; but remember that extra dimension of deep, rumbling, realistic bass you experienced at the movie theater or concert hall? Infinity knows how critical low frequencies are to the full enjoyment of todays high quality multichannel digital music and movie soundtracks. Infinitys PS28, 8-inch, 150-watt powered subwoofer delivers that same rich, clear, dynamic bass response right in your own home. This is the bass that transports you to that exciting movie scene or concert, engaging your senses, commanding attention, and truly delivering the entire sonic experience. Only Infinity Has MMD Used on all PS Series powered subwoofers, Infinitys patented MMD (Metal Matrix Diaphragm) technology transducers deliver crystal-clear, distortion-free low frequencies, even at high listening levels. Unlike paper, polypropylene, or Kevlar cones found in competing speakers, MMD cones consist of an aluminum core anodized with a thin ceramic coating on both sides for increased strength and rigidity. This composite material produces extremely fast, extremely accurate transducers, resulting in a distinctly cleaner, more realistic sound.
