Kraken Quad 21" 8,000W Powered Subwoofer

The BASSBOSS Kraken Quad 21" 8,000W powered subwoofer packs extreme bass into a small footprint. With a sustained SPL of 145dB, this beast of a sub offers the highest SPL on the market from a cabinet of its size. Kraken delivers bass output equivalent to four to five BASSBOSS ZV28 dual 18" subwoofers, but in half the size. No amount of mass-market 18" powered subwoofers could combine to match the Kraken’s performance. Capable of sustaining ultra-deep output down to 25Hz, this quad 21” subwoofer will rattle you to the core, and keep your audiences coming back for more. You don’t know bass until you know BASSBOSS.

The Quad 21” Kraken Powered Subwoofer is designed for large-scale touring systems, high-intensity nightclubs, festival art cars and carnival floats. When you need the most intense bass you can squeeze out of a single cabinet, unleash the Kraken.

Forget everything you ever knew about bass and powered subwoofers. Kraken is a game-changer. Words don’t do it justice. Videos don’t begin to show you the powerful, intense, deep bass Kraken produces. 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.

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 low frequency performance and the horn section provides increased upper frequency sensitivity and improved transient response.

BASSBOSS products are hand-assembled in the USA. They are meticulously constructed from 18 mm 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. The included transport carts also feature recesses that the feet lock into for secure transporting.

The Kraken’s amplifiers are capable of delivering 8000W of continuous output. That’s right—8,000W RMS. This is not a peak or burst power rating, because you’re not going to be using your sub in millisecond bursts. 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.
