The B 18 comprises a single 18″ driver mounted in a vented box, with a sophisticated adaptive port that optimises the airflow and improves its response. This technology, developed through exhaustive research, enables a lower cut-off frequency while having smaller volume. This translates into deeper and dynamic bass from a compact enclosure.

In addition to the speakON® connectors on the back, the subwoofer includes two additional located on the front. This guarantees wiring flexibility and ease of use, reducing setup time even in large configurations.

Finally, the set of accessories specially designed for the B-Line, makes their setup and transportation easier, safer and more comfortable.

Features

The great advantage of powered speakers is the built in amplifier. So there is no need for an external device – the internal amp is optimally matched to the woofer! The B 18A is driven by a mighty 1,600 W
(peak) Class-D amplifier. Integrated DSP presets allow loading of preset system setups that are optimally matched to SE Audiotechnik products.

Thus, the entire system is quickly and easily set up and perfectly adjusted. The directivity can be effortlessly changed in a flash from normal to cardioid or end-fire configuration via the large display and the push/rotary controller.

Parameters such as EQ, Delay, Sensitivity and Phase can be adjusted and stored in your own User Presets.
