Compact by design, massive by nature. The Stackatoa combines the Kraken quad 21 inch subwoofer, the Makara dual 21 inch subwoofer, and the Krakatoa 4-way quintuple 18 inch point source full-range loudspeaker into a vertically stacked powerhouse that delivers unbelievable SPL from just 12 square feet of floor space. Six 21 inch subs + four 18 inch woofers + 18 inch coaxial mid-bass + coaxial mid-high horn. 25 Hz to 19 kHz seamlessly. Winner: 2026 NAMM Best in Show by ecoustics.com.

What we hear from owners
Why the Stackatoa wins where the rig math gets impossible
Patterns from festival production, destination nightclub installs, and outdoor stage builds.
01
Point source coherence wins over line arrays
Every frequency from 25 Hz to 19 kHz leaves the Stackatoa from a single vertical axis. The phase interference that any multi-cabinet line array + sub stack accumulates simply does not happen. Imaging is locked.
02
Twelve square feet is the conversion math
Festivals charge per square foot of audience capacity. The Stackatoa delivers concert SPL from a 4 ft x 3 ft footprint. The audience space you keep instead of giving to the rig is real revenue at scale.
03
25 Hz to 19 kHz in one vertical stack
True full range from a single point. EDM, cumbias, hip-hop, rock, theater, house of worship: every program reaches its foundation without compromise.
04
Wind-resistant stability for outdoor festivals
The vertical stack with locked component sliders resists wind in a way that flown line arrays cannot match without ballast. Outdoor festival production crews specifically cite this.
05
NAMM 2026 Best in Show is the credential
Awarded by ecoustics.com at 2026 NAMM. For dealers and venue operators selling against established European premium-tier brands, the award is the conversation opener.
06
Stereo Stackatoa is the festival main
A pair of Stackatoa stacks (one per side) handles most 5,000 to 15,000 cap festival mains with appropriate sub array support. Production planning gets simpler at this scale.
Decision framework
Is the Stackatoa right for your venue or production?
Buy it for
Festival production at 3,000 to 15,000 cap where audience floor space converts to revenue and point-source coherence matters. Destination nightclub installs at the top of the market (Kingdom Austin pattern). Outdoor stage builds where wind stability and full-range coverage from a single point are the brief. Permanent installs in flagship performance venues, large houses of worship, and arena-sized clubs. Production companies building the BASSBOSS reference rig.
Look elsewhere if
You need standard touring and rental flexibility, where MFLA‑MK3 line arrays over Kraken‑MK3 or Makara‑MK3 sub arrays are what fits scaling per venue. You are running rooms under 2,000 cap, where the Stackatoa is dramatically overspecified. You need any kind of mobile transport, where 555 kg per stack is the wrong cabinet category.

Send a system spec, not a price shopping number
Tell us the room, the audience size, and what you run today. We come back with the right pair, freight, and price. One short form.
Per stack: $43,985 (Krakatoa $17,995 + Makara $7,995 + Kraken $17,995). Stereo (2 stacks): $87,970 plus carts and covers. Festival production typically deploys 2 to 4 stacks plus supplementary sub arrays at the wings. We quote the full rig against your venue and audience capacity.
Q2
Stackatoa versus MFLA line array, which one do I want?
Different design philosophies. MFLA‑MK3 line arrays scale per venue, fly cleanly, and are the touring and rental flexible tool. Stackatoa is the fixed-position flagship system: superior point-source coherence and full-range coverage from a single point, matched to fixed install and large festival mains. Most flagship venues run Stackatoa or pair both.
Q3
How is the Stackatoa transported and assembled?
Each component cabinet has its own transport cart (Krakatoa flat cart, Makara-V-WC vertical, Kraken-H-WC horizontal). On-site assembly stacks the cabinets using the integrated UHMW polyethylene sliders that interlock between cabinets. Forklift access at the venue is the standard load-in for festival deployment.
Q4
Does the Stackatoa stand on its own or do we need wing subs?
For most installs, the Stackatoa stands alone. For festival mains at 5,000 plus cap, supplementary Kraken or Makara sub arrays at the wings extend horizontal coverage. We size systems against your venue geometry.
Q5
What is the system frequency response and SPL?
25 Hz to 19 kHz full-range. Sustained output is in the arena-scale range (143 dB peak on the Kraken alone, 142 dB on the Krakatoa). Aggregate stack output is beyond conventional measurement bench conditions; the BASSBOSS demo room is the default evaluation.
Q6
Can the Stackatoa run cardioid mode?
Yes, with 2 or more Stackatoa stacks via the onboard 96kHz DSP across the Makara and Kraken components. Standard at festivals and destination installs where stage and back-wall control matter.
Q7
Where can I hear a Stackatoa?
The BASSBOSS demo room in Austin runs full Stackatoa builds. Destination installs include Kingdom Austin and similar flagship venues. For festival demos, BASSBOSS deploys Stackatoa builds at Big Fam Fest and select regional festivals each season. We route demo opportunities by region.
System design
Scale the Stackatoa for larger venues
For 5,000 plus cap festival mains, additional sub arrays at the wings extend horizontal coverage.
Add 2 to 4 Kraken cabinets at the wings of a stereo Stackatoa rig for festival mains beyond 8,000 cap. Cardioid configuration recommended for stage control.
For wide audience footprints beyond the Stackatoa horizontal pattern, add MFLA line array side-fills. Combines point-source main with line-array coverage at scale.

Honest answers
Doubts our clients initially had
Before they bought, here is what made buyers hesitate. We talked it through. Short version.
D1
$43,985 per stack feels like a lot.
Per square foot of audience space recovered, per phase-coherent SPL delivered, per year of festival service life, the math works for the right deployment. The Stackatoa is not for every venue; it is for the venues and festivals where the design philosophy matters.
D2
555 kg per stack is real weight.
It is. The Stackatoa is built for fixed-position install and festival deployment with forklift access. The component cabinets have integrated transport carts for between-event movement. For permanent install, the system stays in place.
D3
Point source versus line array, can the audience tell?
In the demo room or at a side-by-side outdoor demo, yes. Phase coherence is felt in vocal intelligibility at distance, in stereo imaging across the floor, and in the way the bass and the mid-high arrive together. Most listeners describe it differently than they expected.
D4
The Best in Show award is marketing.
The award by ecoustics.com at 2026 NAMM is a real industry recognition. But the engineering case stands independently. The 4-way point source, the 6th-order hybrid sub topology, and the 25 Hz to 19 kHz full-range coverage from 12 sq ft are measurable design choices, not marketing claims.
D5
Will the dispersion be too narrow for wide festival audiences?
For dance-floor and audience-aligned deployments, the 60 by 40 dispersion of the Krakatoa is sized correctly. For wider crowds, supplementary AT212 front-fills and MFLA side-fills extend coverage. The Stackatoa is the main; the rig design scales around it.
D6
I want to hear a Stackatoa before committing.
Send your city and timing. The BASSBOSS demo room runs full Stackatoa builds, and festival deployments at Big Fam Fest and similar events offer field listening. For flagship install evaluations, Kingdom Austin and similar destination venues host owner-introduced visits.
