The élite ES200P is an ultra-compact powered subwoofer that features a single 10" speaker and a built in 200 watt power module. The precisely tuned band-pass enclosure of the ES200P provides rock-solid low frequency output previously available only from much larger cabinets. In fact, the unique combination of high-excursion woofers, electronic control and proprietary, series-loaded box design results in higher acoustic output than many single 18" enclosures which are 30-50% larger!
