Engineered to deliver explosive impact from the smallest space possible, this single loudspeaker covers the entire audible spectrum. The Krakatoa focuses its output of seismic bass, crystal-clear highs, and everything in between, from a single point. Start with four 18" subs in a sixth-order band-pass enclosure for high impact and extended depth. Add an 18" mid-bass driver in a sealed enclosure for tight control. Right through the middle, fire a very serious mid-high horn with a state-of-the-art co-axial compression driver to provide pristine, high-efficiency high-frequencies. The Krakatoa delivers all sounds seamlessly from a single point. This ensures the most naturally realistic listening experience that a loudspeaker can produce. Practically eliminating phase interference affords superior sound localization, which allows more precise imaging, immersing listeners in an immense, sharply focused sound field. This is the real immersive.
The Krakatoa is a true full range - from deep, powerful bass to crisp highs, delivering every note with clarity and precision. Its 4-way design assigns each frequency range to dedicated drivers, reducing distortion and ensuring balanced, dynamic sound even at high volumes. How big does it sound? If you hear it before you see it, you won't believe how small it is. The Stack-a-Toa combines the Kraken Quad 21" Subwoofer, the Makara Double 21" Subwoofer, and the Krakatoa into a vertically stacked powerhouse of sound, delivering massive SPL from a remarkably small "dance stack" design. There are all-new amplifiers in the MK3 series. Total power has increased, however, power allocated to woofers increased substantially. The higher output voltages provide more impact. Universal input voltage compatibility of 90-250V provides more flexibility. Waterproof connections provide more peace of mind.
