Bandpass Powered Subwoofer Design: The Turbosound M-18B features a bandpass design that enhances its low-frequency performance. This configuration allows for maximum bass extension while maintaining high efficiency. The subwoofer delivers powerful bass output, making it suitable for both portable PA systems and permanent installations. The design effectively increases the acoustic load presented to the driver, reinforcing bass musical instrument frequencies for a rich, resonant sound.

Class-D Amplification Technology: Equipped with Klark Teknik Class-D technology, the M-18B provides an impressive 2,200 watts of power. This technology ensures remarkable sonic performance while maintaining energy efficiency. The lightweight and compact design allows for easier transport without compromising output power. Class-D amplification also reduces heat generation, which enhances reliability and prolongs the lifespan of the subwoofer.

Custom-Engineered High Excursion Driver: The M-18B houses a high-excursion 18″ low-frequency driver with a 4″ voice coil and double suspension. This driver is designed for maximum performance, ensuring tight and articulate bass response. The combination of advanced materials and engineering contributes to the overall sound quality, delivering clear and powerful low-end frequencies that enhance musical experiences.

Integrated Control Center: The onboard control panel includes a subwoofer level control, a polarity switch for proper phasing, and a switchable boost filter set at 100 Hz. These features allow users to customize the sound to fit their specific needs. Additionally, the control center has XLR thru connectors, enabling easy integration with powered full-range loudspeakers or additional subwoofers.

Durable and Portable Construction: The M-18B is constructed from robust birch plywood with a semi-matt black paint finish that protects against wear and tear. The internal ribbing reduces unwanted vibrations, ensuring clarity in sound. It also includes a rugged powder-coated perforated steel mesh grille to safeguard the driver from damage during transport and use. Plated steel castors with rubber tires facilitate easy movement, making it ideal for gigging musicians and mobile sound professionals.

Versatile Installation Options: This subwoofer features a standard 36 mm pole mount, allowing for flexible speaker placement and optimal audience coverage. Whether used in a vertical or angled position, the M-18B adapts to various setups, ensuring the best sound experience for different venues.

Reliable Performance Indicators: The M-18B includes an illuminated front badge that can indicate different operating modes, helping users monitor the status of the subwoofer. This feature, combined with the integrated fuse holder for mains power connection, enhances usability and reliability during performances.
