15″ – The Space Saver
The most outstanding feature of the models with a 15″ woofer is their easy handling during setup and transport, combined with impressive output performance in operation. By the way, this 15″ subwoofer is available not only in the passive version B 15 and the model B 15A with integrated amplifier and DSP but also as a flyable version B 15A FS. Thus, you can have real bass even in a flown system.
