B-Line 15″
The space miracle
Features
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
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.
