B 15

B 15 is one of our new multi-purpose subwoofer models designed to serve a wide variety of applications.

It features a punchy 15″ speaker, either in an active (B 15A) or passive built (B 15).

The active version is equipped with an 800 Watt class-D amp with integrated DSP crossover.

Features

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.
* B 15A and B 15A W do not have any front sockets.

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.
* B 15A and B 15A W do not have any front sockets.
