CB 15s

Contrabass CB 15s employs a 500 Watt, low-frequency driver using an industry standard 4” (100 mm) voice coil. This low profile subwoofer is the next level up from CB 12s in terms of power. Designed to complement all the Cello series tops, it adds significantly more bass energy and body to the sound, while improving the mid clarity by taking the stress away from the smaller mid drivers on the main cabinets.
Although the speaker comes standard in black, it can custom match any decor upon request, owing to its innovative grill-less design.
For demanding applications, the CSC Maestro MS 26 controller is configured to perform and its EQ and limiter functions are preloaded in the controller. CC 8, CF 10, CF 12 and CF15 are a perfect match for CB 15s
