BSX dual 21" subwoofer cabinet box Description:

Equipped with two powerful 21" drivers with a peak performance potential of 1.2 kW per driver, this speaker is able to reproduce a truly massive bass foundation.

Thanks to the hybrid enclosure principle its efficiency is maximised so that the energy is still perceptible even at a great distance. Primarily the BSX functions as a true sub bass extension.

Because of its extremely stiff yet lightweight membranes the BSX is able to deliver frequencies of up to 120 Hz clean and true to its impulses. As a full range sub the BSX is directly combinable with the M, T, C or VERA systems.
