B 18i is a compact yet powerful passive subwoofer for fixed installation, providing the perfect companion to the AUDIOFOCUS ARES 8 series in standalone, stacked, or flown configurations.

The subwoofer houses a long excursion 18″ neodymium driver and combines front diffusion, bass reflex, and transmission line design for ultimate efficiency and performance.

B 18i is built with pride in Belgium and coated in tough, weather-resistant polyurea to safeguard your investment. The cabinet front is protected by a rigid metal grill, backed by acoustically transparent foam. The subwoofer is supplied with integral rigging and is fully compatible with ARES 8’s rigging system.

We recommend AUDIOFOCUS or Powersoft amplifiers for use with B 18i.
