Electro-Voice QRx 218S 1200 W RMS - 4800 W PMPO Woofer - Black

The QRx-218S is a dedicated subwoofer system that features the excellent low-frequency capabilities of two (2) powerful EVX-180B 18-inch drivers with 4-inch voice coils. In the QRx-218S, these drivers are front-mounted in a compact enclosure that is tuned to 36 Hz and delivers solid bass fundamentals. The 1,200-watt continuous, 4,800-watt peak power handling of the QRx-218S easily provides 133 dB SPL continuous, 139 dB peak output capability at 1 meter. The QRx-218S enclosure has EV's recessed comfort-lift handles on the top and the bottom of the enclosure so the box can be lifted easily. On the back of the standard versions of the enclosure are two (2) sealed pocket wheels at the bottom and two (2) handles at the top of the system so it can be tilted back and moved comfortably by one (1) person. On the rigging versions of the QRx-218S, there are two (2) L-tracks on the top and bottom of the enclosure to allow the system to be hung horizontally or vertically. The standard versions of the QRx-218S are also equipped with a metal 1-3/8-inch mounting socket, for use with a 34-inch pole, to allow elevation of full-range speakers above the sub. The QRx-218S enclosure is built of 13-ply, void-free, grain-oriented birch plywood that is coated with EVCoat, a sprayed on polyurethane finish that is very rugged and weather resistant. The drivers are protected from damage by a 16-gauge powder-coated steel grille with fabric backing. The QRx-218S can augment the performance of even the finest sound systems with high levels of extended bass response.
