When it comes to providing thunderous low end in a powerful, compact enclosure, it doesn’t get much more formidable than the Electro-Voice ETX-18SP. Covering the low end for Electro-Voice’s award-winning flagship ETX series, the ETX-18SP drives an 18-inch DVX woofer with 1800 watts of Class-D power, all sculpted by its integrated FIR-Drive DSP. Portable, potent, and precise, the ETX-18SP delivers like nothing else in its class and is perfect for live sound, DJs, rental companies, and permanent installations where premium sound is required.
What Makes the ETX-18SP Truly Incredible
The ETX-18SP isn’t just about raw power; it’s about intelligent design that translates into unforgettable audio experiences. With state-of-the-art components and road-ready construction, this subwoofer is engineered to perform reliably night after night, delivering the kind of deep, articulate bass that you can feel. It's the anchor of your sound system, providing a solid foundation that allows the rest of your mix to shine.
High-Sensitivity 18-inch Woofer: The custom-built DVX3180A woofer is designed for an extended low-frequency response, reaching down to a room-shaking 28 Hz. This means you’re not just hearing the bass; you're experiencing every subsonic nuance.
1,800-watt Class-D Amplifier: This highly efficient power plant delivers a massive 135 dB peak SPL with incredible clarity and low distortion. It provides all the headroom you need to ensure your low end remains tight and punchy, even when pushed to the limit.
FIR-Drive DSP Technology: Electro-Voice's proprietary FIR-Drive uses sophisticated digital signal processing to optimize the speaker’s performance. This intelligent system corrects for nonlinearities and protects the transducer, resulting in a transparent and powerful sound that's been finely tuned by EV engineers.
True Cardioid Performance: A special DSP preset allows you to create a cardioid array with multiple subwoofers, focusing the bass energy forward towards the audience while significantly reducing stage volume. This keeps your sound clean and your performers happy.
Built for Performance, Designed for the Real World
The ETX-18SP combines brute force with sophisticated technology to deliver a seamless user experience. Every feature is designed with the working professional in mind, from thermal management that keeps the amp cool during hot outdoor gigs to user-friendly controls that make setup a breeze.
Blower-Controlled Thermal Management: The amplifier is designed to work reliably even in hot environments. An internal fan engages as needed to maintain optimal operating temperature, ensuring consistent performance throughout the show.
Advanced Limiter Protection: The DSP features peak and thermal transducer protection that "looks ahead" to anticipate and prevent clipping or damage. The limiters are visible on both the rear LCD and the front-grille LED, giving you a clear visual cue when you're pushing the system hard.
Intuitive Single-Knob Control: The back panel's DSP is managed via a single knob and a large, bright LCD screen. You can easily navigate menus and adjust parameters like crossover points (80 Hz, 100 Hz, 120 Hz, 150 Hz) on the fly.
Tour-Grade Construction
A speaker’s enclosure is just as critical as its internal components, and the ETX-18SP is built to withstand the rigors of the road. Its robust construction and thoughtful design features make transport and setup simple and secure.
Rugged Plywood Enclosure: The cabinet is constructed from 18-mm, 13-ply birch plywood, known for its strength and warm acoustic properties. It's finished with EVCoat, a durable coating that protects against scuffs and scratches.
Combo Pole Cup: A combination pole cup (both insert and threaded) provides a stable and secure mounting point for ETX series full-range speakers, making system setup quick and reliable.
Removable Casters: Transporting this beast is made easy with included removable casters. Simply roll it into place, pop them off for the gig, and reattach them for a quick load-out.
Bring the Bass to Your Next Gig
The Electro-Voice ETX-18SP proves that you don't have to sacrifice portability for power. This subwoofer is a testament to EV's commitment to durability and superior sound, having undergone torture tests that far exceed industry standards. It's a reliable workhorse engineered to provide the powerful, precise low end your sound deserves.
