The EV ETX-18SP is an active 18" subwoofer with integrated DSP, limiter, and FIR filtering – though its most immediately noteworthy feature is its organic, natural sound. It's robust, flexible, and powerful, so it's just as at home in a gigging and touring context as it is in a permanent installation. The subwoofers of the ETX series are available in 15" and 18" sizes, and three matching 10", 12", and 15" top units are available as well. The ETX speakers are Electro-Voice's flagship range, and as such they're recommended for professional musicians, bands, DJs, and anyone who provides sound for live entertainment. The series boasts a number of technical innovations, such as the QuickSmart DSP – more on that below. But one thing is sure: These are speakers that have been designed to take on any challenge.
Accept no compromises in sound and performance: The EV ETX-18SP has a powerful 1800W Class D power amplifier with an efficiency grade that means it keeps cool even in the hottest environments. For maximum punch, the unit's DVX 18" bass speaker operates inside a 18mm thick, 13-ply, road-ready birch plywood chassis. The maximum sound pressure level is a whopping 135dB. The frequency range is 28–180Hz, with a flexible low-pass frequency at 80Hz, 100Hz, 120Hz, or 150Hz. For the crossovers, Electro-Voice uses FIR filter technology, as found in the company's large concert speaker systems. The proprietary FIR drive design optimises the transducer's linearity for a precise, balanced sound output.
Flexibility and workflow are very important aspects of the ETX series: The integrated QuickSmart Pro DSP scores highly on this front thanks to its intuitive menu navigation (via encoder and LCD), input level control, and master volume control, as well as the special dispersion control technology it uses for the subwoofers – for real cardioid performance across the entire operating range. The ETX-18SP features insert and threaded combo pole cups. Two lockable XLR/jack combo sockets are available on the input side. In addition, there are two XLR link outputs for controlling speakers such as the Electro-Voice ETX-15P. The DSP offers EQ and delay adjustments, as well as different presets for all possible scenarios and locations. Last but not least, the ETX-18SP comes with a convenient setup wizard that helps users of all experience levels to install different top/sub combinations.
Electro-Voice was founded in 1927 and has been dedicated to building sound reinforcement systems and microphones since the 1930s. The firm, originally based in Indiana, USA, is considered one of the industry pioneers and has developed many new technologies still in use today. For example, their hum-cancelling coil was not only a milestone for microphone construction, but also was at the origin of the humbucker pickups still used in many guitars. In the long history of the company, Electro-Voice has constantly expanded its offer and today sells a wide range of products for sound reinforcement tasks from entry to professional levels.
Musicians, bands, and AV staging and rental companies looking for a professional subwoofer with powerful sound, DSP, and modern speaker management will find what they're looking for in the ETX-15SP or ETX-18SP. Thanks to their solid, concert-grade construction, they feel at home on every stage and in every setup, providing the necessary low end at concerts and clubs. With the ETX-10P, ETX-12P, and ETX-15P, Electro-Voice also offers the suitable top units. Designed for everyday touring and band life, the ETX speaker family brings a high level of performance and fidelity to the stage. But that doesn't just apply to the biggest stages; even the most ambitious acoustic duos, DJs, and solo entertainers will find that ETX performance woofers tick all the boxes, in terms of audio quality, usability, and durability.
