Hot Thing
Miniscule cabinet, massive sound. The DiaMon-MK3 blows expectations with its power and intensity. This compact cab can easily hang with a double-driver sub without breaking a sweat. Signature co-axial design, signature BASSBOSS output.
Co-Axial Powerhouse
The DiaMon-MK3 puts a 3″ compression driver through the center of the 12″ woofer's pole piece for true co-axial point source output and clarity.
Shine Bright
The DiaMon-MK3 doesn't waste energy trying to reproduce the lows that your subs handle perfectly well. Its 1,200W of amplification is concentrated entirely on the important job of delivering loud, clear mids and highs. It's enough output to keep up with multiple large subwoofers without straining.
Minimal size. Maximal output.
The DiaMon-MK3 packs a high-efficiency 12″ neodymium woofer with a 3″ copper voice coil into the smallest possible enclosure, just big enough to hold the driver, the 1,200W amplifier, and the DSP electronics. CNC-machined Birch plywood with dado joinery and a 35mm steel pole socket. At 14″ × 14″ × 13.5″, it fits in spaces no traditional top does.
Eight presets tuned for how you actually use it.
The MK3's 96 kHz DSP packs 8 pushbutton presets optimized for full-range operation, sub-top crossover modes, outdoor throw, and more. Up to 100 presets stored via ControlBASS software. Every preset includes phase alignment, EQ, HPF/LPF filters, and multi-stage limiting. Load it in, pick a preset, play.
Co-axial clarity, from every seat.
A 3″ diaphragm compression driver mounts through an 80° conical aluminum waveguide machined from the center of the midrange driver's pole piece. Both HF and LF drivers share the same acoustic center, for point source, naturally coherent, even coverage at 80° × 80°. Optional wall and ceiling mounts available for installed applications.
Diving Deep with the Fam.

The DJs are loving the low end. The DiaMons have massive headroom. Had such great feedback... everyone is happy with it.

When only the absolute best sound with no compromise will do in your nightclub bassboss products are the Lambo of PA speakers and subs. Every single component in the construction of the product down to the amplifiers they use are all the best possible parts available. If you are serious about your sound, BASSBOSS.

We recently had a friend—someone who’s played some of the biggest stages out there—perform on our BASSBOSS stage. After her set, she asked, “Who makes that monitor? That’s the best monitor I’ve ever used.” It was a Diamon!

Best 12 inch speaker I've ever ran through my studio. Have spent 1000s of hours listening and have zero complaints. We also use them on all our stages as stage monitors as well and never has had an issue. Very loud and clear. 11/10
