Product Details SX218

Two long-excursion 18-inch ferrite drivers have 4-inch voice coils, water-resistant cones and triple-roll surrounds. Each is rated at 1000 W AES, with the motor and suspension designed for linear excursion.

The birch plywood cabinet has a durable polyurea coating, eight large-area reflex ports and a perforated steel grille. An M20 pole insert adds deployment flexibility. Its two 8-ohm driver circuits use the published amplifier-channel arrangement.

Cabinet wheels are optional. The input-board cover accessory provides the manufacturer-specified weather-resistant configuration for permanent outdoor installation.
