QSC E218SW

The E218sw is a high-performance direct radiation subwoofer with two, 800W, 18-inch, aluminum frame woofers. It?s designed to produce crushing low-end for live performance with kick-drum and bass in the PA or for high-level, high-energy dance music. For portable applications it includes attachment points for four optional casters. The subwoofer?s 4-ohm impedance means that a single cabinet can be optimally powered by a less expensive amplifier.
