Used Electro-Voice ETX-18SP for Sale: A Practical B2B Buyer’s Review
The Electro-Voice ETX-18SP is a powered 18-inch subwoofer that has become a staple in rental inventories and fixed installations where reliable low-end reinforcement is needed without the complexity of separate amps and processors. For B2B buyers sourcing used professional audio gear, this model represents a solid value proposition—provided you know what to inspect, what to ask, and how to navigate the second-hand market. This review covers where the ETX-18SP fits, what specs matter for integration, a used-buying checklist, price context, and how a B2B order typically works.
The ETX-18SP is a 1,800W peak Class-D powered subwoofer with an 18-inch woofer, designed for portable and installed applications. In rental fleets, it pairs naturally with ETX-series tops (ETX-12P, ETX-15P) or other full-range boxes, offering a scalable low-end solution for corporate events, small-to-mid clubs, and live music venues. Its integrated DSP with presets for different configurations makes it easy for rental staff to deploy without deep system tuning. For integrators, the ETX-18SP is often specified for houses of worship, gyms, and multipurpose rooms where a self-powered sub simplifies cabling and commissioning. The key advantage in a used context is that the powered design eliminates the need to match separate amplifiers, reducing integration risk and total cost.
When evaluating a used ETX-18SP, focus on the specs that affect real-world deployment. The 18-inch woofer with a 4-inch voice coil is robust, but check for cone fatigue or surround damage. The 1,800W peak amplifier (Class-D) delivers ample headroom, but ensure the power supply and amp module are healthy—these are common failure points in older units. The integrated DSP offers presets (e.g., for cardioid arrays or standard operation), so verify that the presets are accessible and function correctly. Connectivity includes XLR inputs and outputs, plus a powerCON connector; inspect these for wear. The enclosure is plywood with a durable coating, but check for water damage or deep scratches that could indicate rough handling. Weight (approx. 45 kg) and dimensions matter for truck packs and venue load-ins, so confirm they suit your logistics. Finally, check the frequency response (typically 35 Hz–150 Hz) and maximum SPL (around 135 dB) to ensure it meets your low-end requirements.
