BASSBOSS AT312-MK3 Triple 12 Inch Active Point Source Loudspeaker

The BASSBOSS AT312-MK3 delivers the power and frequency coverage of a complete three way system through a true coaxial point source design. Two 12 inch neodymium woofers reproduce the lows, while a 12 inch midrange driver and coaxially mounted 3 inch compression driver project the mids and highs from the same point in space, virtually eliminating phase interference for remarkably focused, coherent sound. With 4000W of dedicated Class D amplification, 133 dB sustained output, 139 dB peak SPL, and consistent 80° × 80° conical coverage, this single cabinet combines reference monitor detail with the impact required for dance floors, touring productions, performance venues, and compact festival stages.



Why Choose the BASSBOSS AT312-MK3?

Dedicated amplification supplies 2400W to the low frequency woofers, 800W to the midrange, and 800W to the compression driver, keeping each section within its optimal operating range. Integrated 96kHz DSP provides filtering, phase alignment, equalization, and driver protection, while ControlBASS enables remote monitoring and preset management.

Symmetrical coverage, integrated rigging, universal voltage compatibility, and a reinforced Baltic birch enclosure make the AT312-MK3 a flexible choice for professionals looking to buy a powerful main loudspeaker that can be deployed vertically or horizontally without requiring a line array footprint.
