SE B 18

Unrestrained | Compact | Scalable

B-18 is a multi-purpose passive bass-reflex subwoofer with high power SE AUDIOTECHNIK 18″ woofer.

Extremely flat frequency response extends down to 28 Hz.

Smart design ensures easy handling and operation in various applications, including cardioid subwoofer stacks


Port design

Aerodynamic port design reduces distortion and airflow noise. The unique asymmetric shape reduces port noise drastically by (-35 dB).


Sockets at front grill

Convenient multiple Neutrik speakON® sockets in front* and back allows for easy set up ideal for live performances.




Octopus feet

The so called “octopus feet” are made from some flexible rubber/plastic material, which provides good slip resistance.

Cardioid subwoofer setups

Due to the intelligent stacking design and the front* and rear sockets, it is possible to operate our B-Line subwoofers as a cardioid setup without any problems.
