Active Subwoofer, in good condition and full working order This sub features 2 x 8" drivers, an on-board amplifier rated at 70W (but sounding like a much more powerful one) and a frequency response of 21Hz-160Hz. Both speakers face forward and the tall and thin design of the cabinet makes it easier to site than the cube-shaped designs of sub with a single driver.
Front panel controls for quick adjustments are Volume, High-Cut Filter (40-140Hz) and Power On/Off, plus a Power LED indicator. At the rear is a Phase Reverse switch, line inputs on Phono connectors and four pairs of speaker binding posts, should you wish to use the sub as part of a stereo system with small bookshelf speakers, for example.
