What Is the Martin Audio S218 Sub?

The Martin Audio S218 is a passive dual 18-inch subwoofer designed for professional live sound reinforcement. It is part of Martin Audio’s established subwoofer range and has been used extensively in touring, rental, and installed sound applications. As a passive unit it requires external amplification and signal processing to operate.

The S218+ is a higher-specification variant of the S218. Both units share the dual 18-inch driver configuration but the S218+ carries upgraded internal components that deliver improved performance relative to the standard S218. The exact specification differences between the S218 and S218+ are details not provided in this listing beyond the driver configuration. Refer to Martin Audio’s official documentation for a direct technical comparison of the two variants before deciding which suits your application.

The units we have in stock are second hand, in good condition, with original components, and confirmed as perfectly working. We have 8 x S218 and 4 x S218+ available. MC2 Audio E45 amplifiers are available alongside the subwoofers for buyers who need compatible amplification.

Estimated Retail Value and Resale Margin

Martin Audio does not publish a public retail price list. New pricing flows through authorized Martin Audio dealers and distributors. Used Martin Audio subwoofers in good working condition with original components are consistently sought after in the secondary market due to the brand’s reputation in touring and club sound reinforcement.

• S218: 1,200€ per pair (600€ per unit)
• S218+: 1,750€ per pair (875€ per unit)
• MC2 Audio E45: 900€ each
• Secondary market range for comparable units: Details not provided. Check current listings on GearSource and Reverb for live market pricing reference

For rental companies building subwoofer inventory at scale, 8 units of S218 at 1,200€ per pair means 4 pairs at a total of 4,800€ for the full S218 stock. 4 units of S218+ at 1,750€ per pair means 2 pairs at a total of 3,500€ for the full S218+ stock. Buying the complete available stock of 12 units across both variants for 8,300€ total provides a substantial subwoofer inventory from a recognized touring brand.

---

Real Profit Example

A rental company purchases the full S218 stock of 8 units (4 pairs) at 4,800€ total.

They deploy all 8 units as a ground-stacked subwoofer array for club nights and outdoor events at a combined daily rental rate of 960€ per day for the full array.

At 6 rental days across the season, gross revenue equals 5,760€ against an equipment cost of 4,800€. The purchase cost is recovered within that initial deployment window, and the units continue generating rental income in subsequent seasons.

This example uses assumed rental rates. Your actual rates, market, and booking volume will vary. These numbers are illustrative, not guaranteed.

Martin Audio S218 vs Martin Audio S218+: Which One Do You Need?

If your primary requirement is maximum subwoofer unit count at the lowest per-unit cost, the S218 at 600€ per unit is the more efficient choice. If your application demands the higher specification of the S218+ and your budget supports the difference, the S218+ at 875€ per unit is the stronger-performing option. Both are in good condition with original components and confirmed as perfectly working.

What to Consider Before Starting a PA Event Company

If you are entering the PA rental or event production business and are evaluating the Martin Audio S218 or S218+ as your first professional subwoofer inventory, consider the following:

• Amplification requirement: Both variants are passive. You need compatible professional power amplifiers such as the MC2 Audio E45 available from this listing to drive them. Budget for amplifier cost alongside cabinet cost.
• DSP and processing: Passive subwoofers require external crossover, equalization, limiting, and protection settings configured in your signal processing chain. Budget for a professional DSP unit if you do not already have one.
• Transport: No transport cases are mentioned in this listing. Budget for appropriate flight cases or transport solutions for the cabinets.
• Scale of deployment: At 600€ per unit for the S218, this is one of the most cost-accessible professional dual 18″ subwoofer options available in the current used market. Building a 4 or 8-unit subwoofer inventory for under 5,000€ from a recognized touring brand is a realistic starting point for a new PA rental business.
• Insurance: Professional audio equipment at any value requires cover for transit, on-site damage, and liability.

Professional resources including Sasphonik and Boston Pro Sounds provide practical guidance on system configuration and PA company setup for those entering the professional audio market.

Best PA Systems to Use the Martin Audio S218 With

The S218 and S218+ are designed to integrate within Martin Audio’s broader PA system ecosystem. They perform as low-frequency extension components alongside Martin Audio line array mid-high cabinets such as the W8L, W8LC, MLA, and MLA Compact series. Signal processing for the complete system is typically handled through Martin Audio’s proprietary system processing or compatible professional DSP platforms.

For mixed-brand systems where the S218 is paired with non-Martin Audio mid-high cabinets, careful system design including crossover frequency selection, time alignment, and level matching is required to achieve consistent results. For guidance on Martin Audio system integration and mixed-brand system configuration, Stageelectronic is a professional reference used by industry buyers and system integrators across Europe.
