Sub-bass extension for the GALEO XT system. A pair of newly developed 21“ woofers with a voice coil diameter of 135 mm and 70 mm maximum excursion (peak to peak) combine with the hybrid horn construction to ensure undistorted, very high level bass within the usable range from 33 to 150 Hz.

The special housing design guarantees a long throw and low power compression for high-performance applications.
