The Quad 21″ Kraken Powered Subwoofer is designed for large scale festival touring systems; high-intensity nightclubs; art cars/festival floats; and BASS junkies who need the most body + face melting bass they can get. The Kraken will eat you alive!

Crushing,
Inescapable

And you’ll love every minute of it!

The most extreme bass output we can pack into the smallest footprint. The Kraken offers the highest SPL on the market from a cabinet of its size, bar none. The output of 4-5 BASSBOSS double 18” subs has been packed into a cabinet roughly the size of just two.

Monstrously
Beautiful

Capable of almost brutal force, it hits so good. Just like the VS21 Single 21” Powered Subwoofer, excellent transient response is delivered by the efficient performance of short horns at the upper end of the subwoofer range. The extended depth is delivered by the large, vented volume, long excursion drivers, and prodigious power.

Vented
Short-Horn

The Kraken is a vented, short-horn, quad 21” bandpass subwoofer. The four 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.

Sliders
Galore

The enclosures feature UHMW Polyethylene sliders on all four sides, with corresponding recesses in the opposite sides to facilitate interlocking the boxes when stacked. The included transport carts also feature recesses which the feet lock into for secure transporting.

Honorable C Note | Producer

David Lee and friends at BassBoss are all good vibrations. Physically and metaphorically speaking. They’ve poured all their time into something that was really lacking, Low End, and it really shows. Not only do their subs look good on paper but they sound and feel even better.

Edwin Herrera | Owner Pro Audio & Stage, Washington, D.C.

It’s amazing when you are in front of a BASSBOSS system you can carry out a conversation with the person next you while you still fill the bass hitting you in the chest. From the high to low frequency’s it’s all super clear and defined.

Power,
power, power

8000W RMS of amplification and comprehensive DSP is included. The amplifier is rated for RMS output using continuous sine wave signal. This is not a “peak” or “burst” power rating because your sub won’t be used in millisecond bursts. For subwoofer applications, peak and burst power ratings are largely irrelevant.

Continuous
Output

The amplifiers are capable of delivering 8000W of continuous output. This ensures the amps aren’t the limiting factor in the output of low frequencies. Providing abundant power prevents overheating issues and virtually eliminates the damage that clipping a too-small amp can cause.

True Specifications

BASSBOSS technical specs are based on measurements of continuous performance in normal usage. Other manufacturers may specify output based on calculations rather than measurements; measurements outside the operating bandwidth; or on ‘Burst’ or ‘Peak’ readings.

BASSBOSS specifications are conservative compared to most manufacturers. They reflect what the products will achieve, consistently, in the real world. Since the real world is where you’ll be using your gear.

Our proactive philosophy causes specifications to be subject to change whenever improvements are made.

*Peak output is calculated using “industry standard” techniques. These calculation methods create theoretical specifications that are inflated over what can actually be achieved. BASSBOSS real world output specifications are provided as “Maximum Sustained Output” ratings, which reflect actual measured, continuous output levels.

Deep Dive

Hand-Built Cabinets

The Kraken is a vented, short-horn, quad 21″ bandpass subwoofer. The four drivers are loaded into a large acoustical volume that is tuned to a very low frequency, and each is front-loaded onto a short horn. The vented enclosure section provides extended low frequency performance and the horn section provides increased upper frequency sensitivity and improved transient response.

BASSBOSS cabinets are hand-assembled in the USA. They are meticulously constructed from 18mm Baltic Birch plywood, using dado joints, screws, extensive bracing and advanced composite adhesives.

The enclosures feature UHMW Polyethylene sliders on all four sides, with corresponding recesses in the opposite sides to facilitate interlocking the boxes when stacked. Each Kraken includes a transport cart which also features recesses that the feet lock into for secure transporting.

Prodigious Amplification

8000W RMS of amplification and comprehensive DSP. The amplifier is rated for RMS output using continuous sine wave signal. This is not a Peak or Burst power rating. You’re not going to be using your sub in millisecond bursts. For subwoofer applications, “peak” and “burst” power ratings are largely irrelevant.

The amplifiers are capable of delivering 8000W of continuous output. This ensures the amp isn’t the limiting factor in the output of low frequencies. Providing abundant power prevents overheating issues and virtually eliminates the damage that clipping a too-small amp can cause.

For larger events, several arraying options are available. Block arrays, side-by-side arrays and front/back Cardioid arrays can be deployed securely thanks to the interlocking feet. Presets are included in the DSP.

Rugged Drivers

All that electrical amplification power is converted into acoustical energy by four high-efficiency, long-excursion 21″ Neodymium motor woofers.

High-intensity Neodymium magnets are lighter and provide higher efficiency so the result is a lighter and louder cabinet. Split-wound coils produce a more linear force through the range of movement of the cone, which results in lower distortion and improved linearity at high output.

The cones are waterproofed to protect them from possible, accidental exposure to moisture such as rain or spilled beverages. Waterproofed woofer cones also permit the cleaning of drivers that have been soiled in a dirty or dusty environment with the use of a damp cloth. Keep the amplifiers dry and party on!

Waterproofed cones in all products. Optional weatherized and weather resistant loudspeakers have the same acoustical performance as our standard options. If your system is likely to be exposed to rain, ask about IP rated amplification options. If you have need of a system for outdoor installation, ask about Weatherized products.

Focused Tuning

BASSBOSS subs can be connected directly to your mixer with nothing but signal cable in between. The built-in processing is comprehensive and yet minimal manipulation is applied to the signal. The processing includes only a high pass filter and a low-pass filter. There is no need for any EQ in the signal for the speaker to provide a broad, flat frequency response. A sophisticated limiter system protects the woofer from thermal and over-excursion damage.

Plug-and play with peace of mind. Multiple, sophisticated protection systems make the loudspeaker virtually indestructible. You can turn on and turn up, all night, without fear of over-driving to the point of damage.
