The Electro-Voice ETX-18SP is a powered 18-inch subwoofer that has become a staple in rental inventories and fixed installations across the CIS, Middle East, South America, and Africa. For B2B buyers sourcing used professional audio gear, understanding the real market price, what drives it, and how to evaluate a used unit is critical to making a sound investment. This guide breaks down the ETX-18SP's role, key specs, inspection points, price context, and how wholesale orders work so you can buy with confidence.
Where the ETX-18SP fits in rental and venue inventories
The ETX-18SP is a 1,800W peak Class-D powered subwoofer with a 18-inch woofer, designed for portable live sound, DJ setups, and small-to-mid venue installations. In rental fleets, it pairs well with ETX tops or other powered full-range boxes, offering scalable low-end for corporate events, weddings, and club gigs. Integrators use it in houses of worship, bars, and multi-purpose rooms where a self-powered sub simplifies cabling and amp rack requirements. Its 134 dB max SPL and 35–150 Hz frequency response make it competitive for its class, and the rugged plywood enclosure with tour-grade finish holds up to transport. Because it is self-powered, it reduces the need for external amplification, which is a major advantage in markets where amp racks add cost and complexity.
Key specs that matter for integration work
When specifying the ETX-18SP for a project, pay attention to the 1,800W peak (1,350W continuous) Class-D amplifier, which delivers ample headroom for transient-heavy material. The 18-inch EVS-18S woofer with forced-air cooling handles high duty cycles, important for rental use. Connectivity includes XLR/TRS combo input, XLR link output, and a built-in crossover with selectable 80/100/120 Hz settings, making it easy to integrate with various tops. The rear panel offers level control, polarity reverse, and a cardioid mode switch—useful for array configurations to reduce rear rejection. The enclosure is 15mm plywood with a black textured finish, steel grille, and four M10 suspension points for install. Weight is around 45 kg (99 lbs), so plan for two-person handling or casters. For integrators, the ETX-18SP's power consumption and thermal behavior are worth noting: it runs cool under normal loads but needs adequate ventilation in racks or closets.
Used-buying checklist: what to inspect and what to ask
Start with the woofer: inspect the cone for tears, punctures, or signs of re-coning. Check the surround for cracks or separation from the cone. Push the cone gently to feel for voice coil rub—any scraping sound indicates misalignment or overheating. Look at the amplifier module for burn marks, swollen capacitors, or corrosion on the PCB, especially if the unit was used in humid climates. Test all inputs and outputs, including the link output and crossover settings, with a known-good signal source. Verify the cardioid mode switch and polarity reverse function. Ask the seller for a test report or video showing the unit at high output for at least 10 minutes—this reveals thermal shutdown issues. Request the serial number and check for any known service history. For used stock, ask about the grade: A (excellent, minimal wear), B (good, cosmetic scratches), C (fair, functional but cosmetically rough). Also ask whether the unit has been bench-tested with a sweep and impedance check, and whether the original packaging is available for freight.
Price context and total cost of ownership
Used Electro-Voice ETX-18SP prices vary by region and condition. In the CIS and Middle East, expect to pay between $900 and $1,400 for a grade B unit, while grade A units can fetch $1,500–$1,800. In South America and Africa, import duties and freight can push prices 20–30% higher. Compare this to a new unit at around $2,000–$2,300. The total cost of ownership includes freight (a single unit ships on a pallet, typically $150–$400 depending on destination), any needed repairs (re-coning costs $200–$350), and ongoing maintenance. However, the ETX-18SP's reliability and parts availability (EV has a strong service network) make used units a smart budget choice. Rental firms often recoup the cost within 10–15 gigs. For integrators, buying tested used stock reduces capital outlay and allows more units per project.
How a B2B order works: grade, freight, and MOQ
Wholesale orders for used ETX-18SP units typically start at a minimum order quantity (MOQ) of 2–4 units, though some sellers accept single units for sample orders. Grading is standardized: A-grade units are fully tested and cosmetically clean, B-grade have minor scuffs but full functionality, C-grade are functional with visible wear. Always request a test report and photos before committing. Freight is usually arranged by the buyer or via the seller's logistics partner; for international orders, sea freight is common for larger quantities, while air freight suits urgent single units. Ensure the seller provides proper export documentation and packing (original cartons or double-boxed with foam). Payment terms vary: typical is 30% deposit, balance before shipment, with escrow options for first-time buyers. Confirm warranty terms—many used gear sellers offer 30–90 days on functional parts.
Buying a used Electro-Voice ETX-18SP can be a high-value move for rental companies and integrators if you inspect carefully and buy from a reputable wholesale source. Focus on the woofer condition, amplifier health, and test documentation, and factor in freight and potential re-coning costs. With the right due diligence, a used ETX-18SP delivers professional low-end performance at a fraction of the new price, keeping your inventory competitive and your budget intact.
