SE-Audiotechnik – S15 Pro 15″ Active Subwoofer



The S15 PRO is a compact active subwoofer designed especially for the M-Line systems. It is composed by a single 15” driver in a bassreflex configuration, powered by an 800 W Class-D amplifier. Its efficient design and compact size guarantees flexible placement in all kinds of environments. In addition, a two-point SE rigging system allows for safe and easy stacking.

The unit contains a newly designed 800 W Class-D power amplifier and is equipped with 24-bit/48 kHz DSP. By using the LCD screen and rotary encoder, users can control various system parameters such as delay, EQ, filters and more.

The built-in factory presets reduce setup times for existing M-Line systems in various configurations. This makes easy the setup of an end-fire or cardioid setup, by simply choosing one of the dedicated factory presets. Furthermore, custom configurations can be saved as user presets.

Built-in power amplifier & DSP

Each S15 PRO subwoofer is equipped with an 800W class-D power amplifier with switching-mode power supply for minimum weight and maximum flexibility anywhere in the world.
Additionally to that our 24bit/48kHz DSP processor provides signal filtering and ensures maximum driver protection.

DSP Presets

Integrated presets help to quickly load different system setups to be used with various M-F3A and M-F3A Pro configurations.
Setting up an end-fire or cardoid setup e.g. can be done by choosing dedicated factory presets.

Integrated Rigging

S15 Pro subwoofers are equipped with two-point SE stacking system that compromises 2 pieces of slide & lock mechanisms to connect two stacked subwoofers to each other.
The same system is used to connect optional M-F3A SF stacking frame.
Additionally a M20 distance pole thread is available on the top.

Cardioid subwoofer setups

Due to the intelligent stacking design, it is possible to operate our S15 subwoofers as a cardioid setup without any problems.
