Compact 18-inch Subwoofer
|
The Electro-Voice QRX-118S has become the standard for regional sound companies, rental professionals, and contractors who want compact high-performance loudspeakers with concert-grade EV components. Covered with rugged EVCOAT, QRx looks great stacked, on poles, as monitors, or flown with simple, integrated, L-track rigging points.
Unique, fully-rotable asymmetrical horns have a 15-degree downward bias to ensure high-frequency coverage without the need to tilt the enclosure toward the audience. Our powerhouse DH7 large-format driver (three-inch voice-coil, 1.4-inch exit) provides the high-frequency engine, while a selection of DL and EVX woofers anchor the low and sub frequencies. The combination of high-level components, unique design, and versatility make QRX-118S one of the best values in the industry.
QRX-118S features include:
- Concert-proven high-output performance
- Accurate transient detail
- EVX-180B woofer for superior linear excursion
- High sensitivity, 137 db maximum SPL (peak)
- Power handling: 600 W continuous, 2400 W peak
- Rectangular 13-ply birch vented enclosure
- Built-in handles and 1 3/8-inch pole-mount receptacle
- Threaded T-nuts (4) for casters or dollies
- Black EVCoat finish (white by special order)
