Accurate reproduction of the bottom octaves of all music, especially pipe organ, symphonic and rock add that last touch to bring you true you-are-there realism to your listening. Worry not, Definitive has bass down pat. The ProSub 1000 features a 300 Watt amplifier driving a high excursion 10 inch front-mounted direct-radiating woofer that is pressure-coupled to a 10 inch Low Bass radiator on the bottom of the enclosure. The net radiating area of the ProSub 1000 is 39% greater than a single 12 inch woofer but with better speed, pitch definition and control.When you listen to any of Definitive Technology"s award-winning ProSub powered subwoofers, you will discover true state-of-the-art bass performance, extending down well beyond the limits of audibility into the range of purely physical subsonic energy that shakes the body and stirs the soul. This has long been the most exciting, sought after and rarest of audio achievements
