Krakatoa: Seismic Sound, Immersive Experience

The Krakatoa is a 4-way concentric point-source design. This innovative format provides unparalleled clarity and impact, delivering full-range coverage from a uniquely compact form. 

Unmatched Acoustical Coherence

With its point source design, the Krakatoa delivers seamless sound from a single point, virtually eliminating the phase interference that results when multiple sources cover the same frequency range. A singular source point affords superior sound localization and precise imaging, ensuring a consistent and natural listening experience from anywhere in their coverage area.

While immersive audio is the latest buzzword in the industry, the artificially generated and surreal effect that’s being pursued is based on disorientation. The Krakatoa, on the other hand, immerses the audience in an experience that’s not surreal but rather hyper-real. Its focus, accuracy and dynamic power enhance and enlarge the experience so that one feels within the music rather than surrounded by the music.

By combining six 21" subwoofers, four 18" woofers, one 18" low-mid, and a co-axial mid-high horn into just twelve square feet, BASSBOSS has created an extraordinarily efficient system that maximizes audience space without compromising on sound quality or power.

The versatility of the Stack-a-Toa makes it ideal for a wide range of venues and applications. In concert venues and theaters, it delivers powerful sound while maintaining a low visual profile, allowing the focus to remain on the performers. For outdoor festivals, the system provides stable, wind-resistant coverage capable of energizing large crowds. 

Nightclub owners will appreciate how the Stack-a-Toa creates an immersive audio experience that keeps patrons coming back night after night. Even houses of worship can benefit from its clear speech intelligibility and ability to deliver emotional musical intensity when needed.

Elevate Every Event

Whether you’re powering a massive festival or an intimate performance, the Stack-a-Toa ensures your audience hears every nuance and feels every beat. With its balanced design and unmatched efficiency, this system delivers professional-grade sound with maximum impact.

Prodigious Power

The Krakatoa-MK3 features 7,500W of amplification, with an auto-sensing, globally compatible power supply that can run on input voltages anywhere between 90 and 250 Volts. Full output power is available on anything over 110V. The amplifier's peak-output voltage provides intense, high SPL hits while its sustained output is unparalleled in its ability to deliver the liquid lows. The amplifier is passively cooled via its external heat sink and by woofer-generated air flow through the port. When necessary, four radial fans will engage to provide additional forced-air cooling capacity in more extreme conditions.

Every BASSBOSS product comes equipped with amplification, and in every case, a generous supply of power is provided. Headroom is the term used to describe the power that's still available when the sound is at the level required, and the BASSBOSS amps provide ample headroom. While it's necessary to have limiters in the DSP to prevent driver overload, those limiters aren't there to prevent amplifier clipping. There is enough power in every product to reach its maximum SPL without the risk of clipping the amplifier.

In other words, the amplifier is never the bottleneck in delivering powerful low frequencies, dynamic impact and clear sound. This abundant power capacity not only keeps overheating at bay but also eliminates the potential for damage caused by clipping an underpowered amp. With BASSBOSS, you've got the power to keep your sound pumping.

Thumping Transducers

Amplifier power is converted into the much more desirable acoustical power by a massive dose of drivers.

High Frequency: Co-Axial Compression driver featuring a 4 in. (100mm) diameter Ring Diaphragm Midrange and a Co-Axially positioned 2.5” (64mm) voice coil Ring Diaphragm Tweeter exiting via a 2” (51mm) throat horn mounted through the center of the 18” Woofer’s Pole Piecer

Mid-Frequency: 18 in. diameter (450mm) neodymium motor bass driver with 4” (100mm) voice coil

Low Frequency: 4 x 18 in. diameter (450mm) neodymium motor woofers with 4 in. (100mm) voice coils, waterproof cones

Neodymium magnets are lighter, and their higher intensity provides higher efficiency, so the result is a lighter and louder cabinet than those with ferrite drivers.

Our split-wound woofer coils create a more consistent force throughout the cone's range of movement, minimizing distortion and enhancing linearity at peak output.

The protection systems involve several techniques running simultaneously to effectively prevent thermal overload of the voice coils and limit excessive excursion. Reducing thermal saturation not only prevents burned voice coils, it also minimizes long-term thermal compression. Due to the sophistication of these multiple, independent yet simultaneous processes, the drivers can be protected while the actions of the limiters have virtually no noticeable effect on the transient response of the loudspeaker. Peak output can be achieved consistently, repeatedly and safely.

We understand that real-life situations can sometimes be messy. That's why we've waterproofed our cones to withstand accidental exposure to moisture – whether it's an unexpected rain shower or a spilled drink.

Choice Cabinets

The Krakatoa-MK3 is a hybrid 6th-order bandpass cabinet, utilizing a large vented volume and four short-horn sections to increase sensitivity in its upper operating range. The four low-frequency drivers are loaded into a large acoustical volume that is tuned to a low frequency, and each is front-loaded onto a short horn. The vented enclosure section provides extended deep bass performance and the horn section provides increased upper-frequency sensitivity and improved transient response.

The mid-bass section utilizes a sealed enclosure loaded with an 18" tri-axial driver with a 4" low-frequency voice coil. Mid-range and highs exit through the concentrically-mounted horn the source of which is coaxial compression driver. This design provides many benefits.

Exceptional Sound Coherence: The Krakatoa’s 4-way point source design delivers sound from a single point, ensuring a consistent and cohesive audio experience with minimal phase interference.

Full Range Coverage: The Krakatoa covers the entire frequency spectrum, from deep bass to crisp highs, with exceptional clarity, making it ideal for a wide range of applications.

Superior Imaging and Sound Localization: The Krakatoa’s point source design provides precise imaging and sound localization, creating an immersive and involving listening environment.

‍Advanced 4-Way Design: The 4-way configuration allows for optimal distribution of frequencies, with dedicated drivers for very lows, mid-lows, mid-highs, and ultra-highs, resulting in balanced and detailed sound reproduction.

BASSBOSS cabinets are designed to endure for a very long time.
