BASSBOSS DiaMon MK3 Description

BASSBOSS DiaMon MK3 is engineered for professionals who need powerful sound reinforcement in an ultra-compact footprint. The integrated 1200W Class-D amplifier provides 900W to the low-frequency woofer and 300W to the high-frequency compression driver, producing a frequency response of 50 Hz to 19 kHz with impressive detail and impact.

The coaxial driver arrangement places the high-frequency driver directly through the center of the woofer, creating highly coherent sound reproduction and smooth off-axis response. This design improves intelligibility, enhances audience coverage consistency, and increases resistance to feedback in live environments.

The extensively braced Baltic birch enclosure combines durability with portability, while the waterproof-coated woofers and Neutrik powerCON True1 TOP connectors provide added reliability for outdoor and demanding event applications. The sealed enclosure design also allows flexible DSP tuning for either deeper low-frequency extension or maximum SPL performance.

The upgraded MK3 DSP platform operates at 96 kHz and supports eight onboard presets with storage for up to 100 presets accessible through Ethernet control. Using ControlBASS software, users can remotely configure systems, group multiple cabinets, monitor temperatures and levels, and integrate seamlessly with other BASSBOSS loudspeakers.

With its compact size, lightweight construction, and professional-grade output, the DiaMon MK3 is ideal for DJs, clubs, houses of worship, touring productions, and installed sound systems requiring premium audio performance in limited space.
