B-Line

B 15A
The space miracle. The most outstanding feature of the models with a 15" woofer is their easy handling during set-up and transport in combination with their impressive output power during operation. Thanks to its very compact dimensions, space is saved in storage and during transport, set-up is quicker and easier and you save on man- and muscle power – especially when flying individually or in an array. The 15" woofer boasts a 3" voice coil, so that even the smallest member in our family can already shows a stage presence of 136 dB max. SPL. The passive 15" subwoofers feature a powerful load capacity of 1,600 W Peak, the active ones are fitted with an 800 W Class-D amp.
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 , 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.
