The E18SW is a high-performance direct
radiating subwoofer with a single, 800 W,
18-inch, aluminum frame woofer. It is
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.
