Versatile Sound & Installation Options With The KB12A

Our new PA speaker has been designed for use in both portable systems, as well as in permanent installs. Constructed from a tough, lightweight ABS cabinet, this speaker will take the tough knocks of live use, whilst still guaranteeing you a great sound every time.

The KB12A comes with all the mounting options you could possibly need; a poll mount slot, rigging points at the top and rear, as well as rubber feet and integrated stacking system. You can even side mount it for use as a stage reference or feedback monitor.

The sound reproduction is handled by a 12 inch mid/low frequency driver and a 1 in throat compression driver tweeter, with a 2.0KHz electronic crossover, ensure that you get a clear, broad and wide ranging sound across all frequencies; high, mid or low. With simple complementing inputs and controls, you will be up and going with a great sound in no time at all.

Press Reviews

This speaker was awarded 4 out of 5 by Music Radar - a leading online publication for musicians.

"If you are looking to buy a Mackie Thump TH12A, we would certainly consider the 250W12 a great alternative."

"Can be put on its side, plus it has a pole mount and stacks with other 250W12's, making it a good choice for all sorts of PA scenarios."

"The 250W12 is...great as a keyboard or vocal wedge, or as part of a PA for mobile DJ's or in club installs."
