Description

B24i – Rethinking the Subwoofer

The B24i is equipped with two 12" speakers, specially designed as a cardioid subwoofer extension for the ELLA6 system. At the same time, it is also the ideal choice for powerful bass extension in combination with other TWAUDiO tops.

The B24i is different

Unlike conventional cardioid subwoofers, which typically feature a large speaker at the front and a smaller one at the rear, the B24i adopts a symmetrical concept: the 12” speakers are positioned at the front and rear of the enclosure.

This design was specifically developed for applications where stage depth is limited due to structural constraints or other requirements. The B24i can be positioned space-savingly with its long side against a stage wall, and a specially tailored preset ensures that both 12" speakers emit sound identically. The wall acts as an additional boundary surface, enhancing sound pressure by an additional 3 dB.

Perfect for cardio operation and flown installations

The B24i can be seamlessly operated in cardio mode, for instance, in combination with the ELLA6. The specially developed high-performance drivers are designed for exceptionally low weight, ensuring minimal load on existing mounting points, particularly in flown applications such as theaters.

For flown setups, two mounting options are available: a bracket for a single B24i and another for two B24i units arranged vertically. The symmetrical enclosure design ensures that speakers and ports are perfectly aligned, delivering consistent and homogeneous sound dispersion.

Compact system with maximum performance

Whether flown or ground-stacked, the B24i, combined with the ELLA6, delivers a directional PA system that covers the entire frequency spectrum in a compact footprint. Its space-saving design ensures no compromises on performance.

With the B24i, TWAUDiO illustrates how standards can be sensibly enhanced using updated approaches.
