QRx218S

Dual 18” Subwoofer

Loudspeaker System

General Description:

The QRx-218S is a dedicated subwoofer system that features
the excellent low-frequency capabilities of two powerful EVX­180B 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 capacity 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 sealed pocket wheels at the bottom and two handles at
the top of the system so it can be tilted back and moved
comfortably by one person. On the rigging versions of the
QRx-218S, there are two 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 and are
shipped 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 Futura, 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 enclosure is available in black or white finishes,
with or without the rigging hardware. When paired with a
powerful, high-quality amplifier such as EV’s P1201 Modular
Precision Series or the P3000 Precision Series units, the QRx­218S can augment the performance of even the finest sound
systems with high levels of extended bass response.
