On Point.
Point source coherence, every frequency.
The Stackatoa's full-range top, four 18″ woofers and one 18″ co-axial driver, fires from a single point in space, anchored by six 21″ subwoofers below. No phase interference or comb filtering, just a perfectly coherent sound field from 25 Hz to 19 kHz.
Concert power in twelve square feet.
22,500 watts of Class D amplification across the stack. 145+ dB of system SPL. 4 ft × 3 ft footprint, 10'4" tall. Festival-grade sound on a floor plan that fits anywhere.
Six 21" subs. No compromise.
15,000W of amplification driving four 21" neodymium subs in the Kraken plus two more 21s in the Makara. Sixth-order hybrid enclosures keep the lows tight, fast, and deep to 25 Hz.
Built for the odds against you.
CNC-machined 18mm Baltic Birch with dado joinery, polyurea armor, outdoor-rated finishes. Designed to be the rig you bought twenty years ago that still shows up to every gig.
Tune three cabinets as one.
Every cabinet runs the MK3 platform. 96 kHz onboard DSP, the Stackatoa settings, and ControlBASS manage the whole system from a laptop. Phase-aligned, preset-managed, network-controlled.
One stack. Best in Show.
eCoustics named the Stackatoa one of its Best in Show picks at NAMM 2026: 'We don't usually cover PA systems, but Bassboss made ignoring this one impossible.'

This is a wonderful equipment for DJ! It is playing the low range that can not be compared with other subwoofers. It surpasses Martin’s triple 15-inch woofer and two 18inch L-Acoustics subs. I can listen to the sounds that I could only listen to at the concert venue in my room. My friends call me crazy, but the music is asking for it. (Translated from Japanese by Google)
