Turbosound MS218 - 8000W 2 x 18-inch Passive IP54-Rated Band Pass Subwoofer in Black Finish

The Turbosound MS218 is a high-performance, dual 18-inch passive subwoofer designed to provide exceptional low-frequency extension and impact for a wide variety of applications. Whether in fixed installations, portable sound systems, or touring setups, the MS218 is ideal for reinforcing bass frequencies in both speech and music sound reinforcement scenarios. With an 8,000 Watt peak power handling capacity and 2,000 Watts continuous, the MS218 delivers powerful and deep bass that fills large spaces with impactful sound. Its seamless integration with Lab Gruppen amplifiers and Lake DSP allows for optimal front-of-house (FOH) performance, offering flexibility and adaptability to different venue requirements.

Designed for the highest performance standards, the MS218 features two 18-inch neodymium low-frequency drivers that provide excellent bass reproduction with low distortion. The subwoofer's advanced low-distortion design ensures clarity even at high output levels, making it perfect for both musical instruments and deep bass effects. Its front-loaded dual driver configuration delivers a punchy and precise response, allowing for efficient bass reproduction in both indoor and outdoor venues. The steep cut-off slopes ensure smooth acoustic transitions when used with Turbosound's MV212 line array elements, providing superior integration and full-range frequency response.

The MS218 is engineered with flexibility and versatility in mind, providing users with multiple options for sound reinforcement configurations. It is optimized for cardioid-array configurations, with electronic delay steering that allows for superior rear rejection and pattern control. When used in reverse cardioid configurations, multiple MS218 enclosures (two front-firing and one rear-firing) provide even more directional control and bass impact. This makes the MS218 ideal for large-scale events where precise low-frequency control and rear rejection are required.

Constructed from 18 mm and 21 mm marine birch plywood, the MS218's enclosure is designed to withstand the rigors of touring and outdoor environments. The enclosure is finished in a highly durable semi-matte black polyurethane coating, ensuring long-lasting performance and a professional appearance. The rugged construction includes an internally braced, vented design that minimizes resonances and maximizes the subwoofer's output power. The subwoofer also features a front-mounted, powder-coated perforated steel grille that provides driver protection while maintaining the system's durability. With its IP54 rating, the MS218 is dust and water-resistant, making it suitable for outdoor events and challenging environments.

The MS218 also includes an advanced four-point suspension system designed for easy and secure rigging. This suspension system allows for safe ground stacking or mounting of multiple units, with the flexibility to stack up to 12 MS218 elements at a 10:1 safety factor. The subwoofer is compatible with Turbosound's TQ and MANCHESTER series, making it a powerful addition to any large-scale sound system. The unit is equipped with Neutrik speakON NL4 connectors, ensuring secure connections and reliability in demanding applications. A front-mounted speakON connector is provided for rear-firing cardioid operation, while the rear panel carries additional speakON connectors for input and link connections.

Optimized for maximum sound quality and performance, the MS218 delivers a frequency response of 30 Hz to 95 Hz (+3 dB) and a maximum SPL of 145 dB, making it ideal for high-output sound systems in venues of all sizes. Whether used for music festivals, concerts, corporate events, or outdoor festivals, the MS218 delivers precise, high-impact bass with unmatched clarity and power.
