The E18SW is a high-performance direct radiation subwoofer with a single, 800W, 18-inch, aluminium frame woofer.

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.

A threaded, M20 pole socket and speaker pole are provided for sub/satellite use with any of the E Series two-way models. For portable applications it includes attachment points for four optional casters.

The subwoofer’s 4-ohm impedance means that a single woofer can be optimally powered by a less expensive amplifier.
