Description

TW AUDiO'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 TW AUDiO's M, T, C and VERA series.

BSX Serious low throw.

California Festival Summer with VERA

VERA20 and VERA36 sound reinforcement systems have won over Californian audiences this summer courtesy of appearances at a succession of highly varied regional festivals.

VERA not dampened by record-breaking rains
for farewell concert

Bringing unparalleled energy to live shows with an enticing mix of ska and hip-hop, La Raíz is one of Spain’s most unique bands. For their momentous Valencia concert, a TW AUDiO sound system was deployed to help reinforce the band’s animated music, which certainly wasn’t tempered by uncharacteristically stormy weather.
