The whole spectrum.
One point.
Kicks Some Serious Ash.
Four 18″ subs in a sixth-order band-pass enclosure. An 18″ mid-bass driver in a sealed enclosure. A co-axial compression driver right through the middle. One cabinet. The whole frequency range.
Seismic Sound.
Single concentric point source: every driver firing from the same axis. Phase interference practically eliminated. The most immersive listening a single loudspeaker can produce.
Volcanic Volume.
4-way design: dedicated drivers per frequency range. Low distortion, balanced output even at peak SPL. Hear every note at every volume.
7,500W. Never the bottleneck.
Auto-sensing 90–250V universal supply. Passive cooling through external heat sink and woofer airflow. Four radial fans engage only when conditions demand.
Built to outlast the gig.
CNC-machined 18 mm Baltic Birch, dado joinery, polyurea finish. 16 M10 fly points. UHMW Polyethylene sliders on every face for ground stack and transport.
The Stackatoa system.
Pair with Makara + Kraken for the complete Stackatoa dance stack: six 21″ subs + four 18″ + 18″ mid-bass + co-axial mid-high. 12 sq ft of floor. 10′4″ tall.

Hands down, I was there yesterday at NAMM—it was insane! The demos were next-level. This setup isn’t for the average listener—it's on a whole different plane compared to even top-tier systems. David is absolutely wild! The kicks hit so low and hard, you can literally feel your blood moving through your chest. It was unreal… I’m still dizzy from it! 😂

I love this F'ing System. Dubstep for Life. (Written on the SSP218 subs at nightclub Barcelona Austin!)

This is probably the ultimate speaker setup. I’m opening a live music venue in Thailand next year, and BASSBOSS is definitely the system I’m going with. Planning to start with two ZV-28s and two DV-12s, and hopefully add a pair of 21s down the line. As much as Krakatoa setup is my dream, it would probably blow my customers straight out of the bar—right into the one across the street! 😂 Absolutely love it.
