B-LINE
B-15 / B-15A / B-15A FS
Multipurpose | Low Distortion | Easy Handling
The B 15 comprises a single 15″ 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! In the B 15A and the B 15A FS, an 800 W (peak) Class-D amplifier is at work. 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.


If there is no room for floor subwoofers in front of or under the stage, but low frequencies need to be reproduced cleanly and powerfully, then you have to fly the sub. That’s why we’ve given the B 15A a flying harness, making the B 15A FS the most versatile model of the B-Line. Like the B 15A, it can be operated on the ground or in a stack, but can also be flown by means of a quick and easy-to-attach flying grid. From 34 Hz upwards, the flying subwoofer provides support from lofty heights with rich bass, if required. The B 15A FS delivers 133 dB max SPL and is impressively powered by an 800 W (peak) Class-D amp with a wide range of adjustment options.
