A high-end active subwoofer designed to complement the ETX series
The Electro-Voice ETX-15SP follows a "performance first" approach: offering an amplified subwoofer capable of keeping up with powerful active speakers while remaining practical to deploy. Its 15-inch format aims for the perfect balance between bass depth, impact, and size, making it a particularly relevant choice for mobile setups, service providers, and installations seeking solid bass without resorting to overly bulky volumes.
Its construction from 13-ply 18 mm birch plywood with EV Coat finish reflects a clearly professional orientation: durability, rigidity, and longevity in daily use, even during repeated loading and stage conditions.
Who is it for and what for: live, DJ, events, fixed installations
The ETX-15SP is aimed at users who want a true reinforcement in the low end : live bands (more present kick and bass), DJs (firm and clear bass), corporate events (full sound at controlled volume), or fixed venues (bars, clubs, multipurpose rooms). Thanks to its frequency range reaching down to 32 Hz (-10 dB), it provides a sense of foundation and breadth while maintaining precision to avoid "muddy" bass.
It is also an excellent choice for building an expandable system: one subwoofer to start, then a second to increase level headroom and better cover larger spaces.
Settings, connectivity, and design: efficient integration in sound systems
Optimized filtering and connection
The ETX-15SP offers an adjustable crossover frequency (80/100/120/150 Hz) to tailor integration with the rest of your system: to relieve small satellite speakers, complement larger speakers, or configure for "punch" depending on musical style. This setting allows for cleaner low-mids and a more intelligible mix, especially at high volume.
Stage-ready connectivity
With 2 Combo Jack 6.35mm TRS/XLR inputs and 2 XLR pass-through outputs, integration is straightforward in most sound chains: mixer, DJ controller, processor, or speaker output. The XLR pass-through facilitates daisy-chaining to active tops or other elements for simple and clean cabling.
Robust enclosure and reliable protection
The 13-ply 18 mm birch plywood cabinet ensures a rigid structure, favorable to cleaner and better-controlled bass. The EV Coat finish targets resistance to scratches and heavy handling. Finally, the 16AWG powder-coated steel grille protects the driver against impacts and transport hazards, a crucial point for regular performances.
