$2,099.00
The Electro-Voice ETX-18SP is an 1800W powered 18-inch PA subwoofer designed to deliver high-output bass reinforcement for DJs, live bands, touring sound systems, event production companies, and professional venues. Equipped with an EV-engineered DVX3180A 18-inch woofer, a high-efficiency Class-D amplifier, and integrated FIR-Drive DSP processing, this subwoofer produces up to 135 dB peak SPL with a frequency response of 33 Hz to 150 Hz and extended low-frequency performance down to 28 Hz (-10 dB). Its advanced signal processing provides selectable crossover frequencies, system presets, protection limiting, and dedicated cardioid array processing for compatible multi-subwoofer configurations. A durable 18 mm plywood enclosure with EVCoat finish, removable casters, and a combination speaker pole mount make it suitable for demanding portable and installed sound applications.
The Electro-Voice ETX-18SP delivers high-output, extended low-frequency performance in a rugged powered subwoofer designed for professional sound reinforcement. Its EV-engineered DVX3180A 18-inch woofer is driven by an integrated 1800W Class-D amplifier, producing up to 135 dB peak SPL for demanding bass applications. With a frequency response of 33 Hz to 150 Hz (-3 dB) and an extended frequency range of 28 Hz to 180 Hz (-10 dB), the ETX-18SP provides the low-frequency foundation needed for DJ performances, electronic dance music, live bands, concert production, and larger PA systems. The powered design eliminates the need for a separate amplifier, simplifying equipment configuration and system setup.
Integrated FIR-Drive DSP processing provides precise control over the subwoofer's acoustic performance. Using finite impulse response filtering and advanced limiting algorithms, the system optimizes transducer operation while providing independent peak and thermal protection. The DSP menu includes selectable crossover frequencies of 80 Hz, 100 Hz, 120 Hz, and 150 Hz, along with optimized settings for compatible full-range loudspeakers. Music and Live application presets allow the system to be configured for different audio requirements, while additional settings provide equalization, system monitoring, and protection controls. An integrated LCD screen and single rotary control make adjustments accessible directly from the rear amplifier panel, and the front LED can be configured to indicate either power or limiting activity.
For applications requiring controlled bass direction, the ETX-18SP includes a dedicated true cardioid DSP preset. When multiple matching ETX-18SP subwoofers are positioned in a supported cardioid configuration, this processing helps reduce low-frequency energy behind the speaker array while maintaining strong bass output toward the audience. This is especially useful for concert stages, live bands, festival production, and event setups where controlling excessive bass behind the PA system is important. The subwoofer also features two XLR/TRS combination inputs and two XLR link outputs, allowing audio signals to be routed between connected loudspeakers and additional subwoofers.
Built for demanding professional use, the ETX-18SP features an 18 mm plywood enclosure finished with protective EVCoat and reinforced by a heavy-duty 16 AWG powder-coated steel grille. Its low-profile cabinet incorporates removable professional-grade casters for easier transportation between venues, with the option to remove the wheels for fixed installations. A combination pole receptacle accepts compatible threaded and non-threaded speaker poles, allowing full-range loudspeakers to be mounted above the subwoofer when appropriate. With its high-output amplifier, intelligent DSP, rugged construction, and versatile connectivity, the ETX-18SP is suitable for mobile DJs, touring productions, live music venues, event production companies, and permanent professional PA installations.

Loud as hell but blows speakers often, I even blew 2 Peavey Lomax's. No slapping, no red light, no clipping. When I bought mine they were $1200 can't figure out why they are 700 more than back then.
