High Power Subwoofer

Passive high power subwoofer equipped with two newly 18" long excursion neodymium speakers. The direct radiating design assures a extraordinary powerful and precise bass response at highest SPL down to the frequency limit of 25 Hz. Its bassreflex design has been optimized to minimize the flow noise. Due to the very low frequency tuning, the sound impression is voluminous but precise and responsive. The GB 218 is characterized by compact enclosure dimensions.

Where To Buy

The GB 218 is recommended as the system subwoofer for setting up bass arrays in combination with the GALO G 10 line array. It completes the precise and high resolution character of the sound system. The GB 218 is designed for applications in horizontal or upright position.

Special features

The stable mechanical construction guarantees the typical K.M.E. durability. Functional details such as optimally placed and ergonomically shaped handles, side edge protectors and stacking elements ensure a easy handling for touring.

Simulation software

The included simulation data for the EASE Focus 3 software allow a precise simulation of the complete sound systems‘ performance in 3 dimensions. Complex subwoofer arrays with omnidirectional or directional dispersion can be simulated by the user.
