B-Line 15″

The space miracle

B 15

B 15A

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.

B 15A FS Stack

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.

System configurations

2x B15A, B 15 SFi, 4x M-F3A PRO

3x B 15A (cardioid), B 15 SFi, 4x M-F3A PRO

Thanks to the system architecture and integrated DSP amplifier of the B-Line subwoofers, the B15 SFi M and B15 SFi L35 stacking frames allow you to create complete stacking systems quickly and safely. You can combine the 15″ B-Line subwoofer directly with our top-of-the-range M-F3A PRO and L 35 line array modules.

In no time you have a speaker system that covers the entire frequency range evenly and accurately, yet is super compact. All the other loudspeakers in our SE AUDIOTECHNIK range are also included in the system and can, for example, be mounted on the B-Line subwoofers using a distance rod; or – placed on a stand next to the subwoofers; or – flown in a rack above the subwoofers.

As you can see, the possibilities are endless. This also works with the passive B-Line versions, as all our external amps share the same DSP and preset structure.
