BassBoss DiaMon-MK3 Single 12 inch Powered Loudspeaker
The DiaMon-MK3 packs a 12-inch neodymium woofer and a 3-inch diaphragm compression driver into a cube roughly 14 inches on a side that weighs 30 pounds. The horn fires through the woofer's pole piece into an 80 by 80 degree conical waveguide, so the two drivers behave as a single source and the coverage pattern stays the same whether the box is on the floor as a wedge, on a pole, or hung as a fill.
A two-channel 1,200-watt Class D amplifier drives it to 123 dB sustained and 126 dB peak across a 50 Hz to 19 kHz range. As with the rest of the MK3 platform, the 96 kHz DSP carries eight pushbutton presets and stores up to a hundred over the network through ControlBASS, so a monitor preset, a fill preset, and a full-range preset can all live on the same box. Optional ceiling and wall hardware is available for permanent installs.
