They deserve every penny!! I’ve wanted the speakers to be loud but at the same time provide a flat and clean frequency response without distortion because most of the PA speakers in the market, they cannot maintain the flat frequency response, they might either have a muddy, harsh, etc. sound. With my speakers, I got the same quality as my near field studio speakers, and plus I can crack the volume higher and be able to use it on my small parties. Definitely recommend it!

Even at a quarter power, this system absolutely crushes it. The sound is thick and tight. I’ve taken a third of the system out and the sound still blows everyone away. It’s incredible how loud and clear, rich and sweet they are. Playing on them feels like magic. Every time I turn them on I smile to myself.

The human range of hearing starts at 20 Hz. Why settle for 40 Hz? BASSBOSS creates pure, powerful and natural low-end. When listening to acoustic tracks I heard and felt depth in the music that I haven't gotten from other speaker manufacturers.

BASSBOSS sound is incomparable. You can have the #1 artist performing at your event, but if the sound system is not up to par then neither is your performer. When you are in front of a BASSBOSS system you can carry out a conversation with the person next you while you still fill the bass hitting you in the chest. From the high to low frequency it’s all super clear and defined.

See how the Makara-MK3 compares to the rest of the BASSBOSS low-end product line.
The Makara is best in complete BASSBOSS systems: sub and tops, designed to support each other.
The Makara-MK3 in complete systems: subs and tops, dialed in and ready to go.

The Makara is the mid-level anchor of the Stackatoa system. Pair with Krakatoa tops for a self-contained festival rig that flies, stacks, and scales.

Line array above, 21″ below. The MFLA-MK3 hangs from the rigging while the Makara drives the room from the floor. ControlBASS ties both into one system.

Matched SPL ceiling means the tops never have to work harder than the sub. Full-range system that gets booked again.

Two 12″ drivers with serious SPL headroom. A natural partner for the Makara on mid-scale productions.
