Efficient | Flexible | Versatile

The new S12 PRO is an upgraded subwoofer for the M-Line family, building on the success of the SUB 112BR. The subwoofer consists of a single 12” driver in a bass-reflex configuration, and features an updated 800W Class-D amplifier. Its efficient design and compact size guarantees flexible placement in every environment.

A two-point SE rigging system allows for safe and easy stacking, while the improved port design increases the overall performance, reduces the port-noise and helps to maximize system SPL.

The newly designed amplifier helps to deliver plenty of punch with higher SPL levels than its predecessor. Equipped with a cost-effective, yet flexible DSP system there is no need for external signal processing.

Integrated DSP-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 cardioid setup can be done quickly and simply by choosing one of the dedicated factory presets.

Users can also individual control various parameters such as gain, EQ, filters, delay and more. The new amplifier panel can be extended with an additional rain-protection cover, that helps to protect the electronics from rain and outdoor environments.



Built-in power amplifier & DSP

Each S12 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

M-F3A S12 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 S12 subwoofers as a cardioid setup without any problems.
