TWAUDiO's biggest subwoofer to date, the Big Subwoofer eXtender (BSX) employs two immensely powerful 21" drivers, each delivering 7.2 kW peak, to create a massive low-end foundation for the biggest of systems.
Even in the biggest of stadiums, the hybrid design of the BSX ensures that this true sub bass extension will be felt as well as heard.
The use of extremely stiff yet lightweight membranes allows the BSX to deliver frequencies of up to 120 Hz with no sacrifice in fidelity.
As a full range sub, the BSX is fully compatible with all TWAUDiO series.
