BASSBOSS Kraken-MK3 - 10000W 4 x 21-inch Powered Vented Bandpass Subwoofer with 4.5-inch Voice Coils and 360-Degree Coverage in Black Finish

The BASSBOSS Kraken-MK3 is a monumental subwoofer designed to deliver earth-shaking, face-melting bass with unmatched efficiency and power. It's a system engineered for those who demand the deepest, most intense low-end frequencies, without compromising on the clarity and punch needed for high-energy events. The Kraken-MK3 combines the raw power of four 21-inch neodymium woofers with cutting-edge design, making it the ultimate subwoofer for festivals, touring systems, nightclubs, art cars, and serious bass enthusiasts. Whether you're shaking the foundations of a massive venue or adding that extra dimension to an art installation, the Kraken-MK3 delivers monumental bass that envelops your audience in a way that few other systems can.

At the heart of the Kraken-MK3 is its staggering 10,000W total amplification, powered by four discrete 2,500W Class-D amplifiers. Each amplifier is dedicated to one of the four 21-inch woofers, ensuring that the power is spread evenly across the subwoofers for maximum performance and efficiency. The auto-sensing, globally compatible power supply allows the Kraken-MK3 to operate seamlessly on input voltages between 90V and 250V, meaning it can be used worldwide without the need for external adapters or converters. The amplifier's peak output voltage enables intense, high SPL bursts, while its sustained output ensures smooth and powerful low-frequency reproduction without overheating. Passive cooling is provided through an external heat sink and air flow from the woofers, and four radial fans kick in during extreme conditions to keep the system running cool and stable.

The Kraken-MK3 features a hybrid 6th-order bandpass design, incorporating two short-horn sections and a vented enclosure to produce an optimal balance of deep bass extension and punchy upper frequencies. The woofer design utilizes massive 21-inch neodymium motor drivers with 4.5-inch (115mm) CCAW split-wound voice coils and waterproof fiber composite cones. These drivers provide exceptional sensitivity, high displacement, and excellent thermal stability, while the neodymium magnets contribute to the overall efficiency of the system, making the Kraken-MK3 both lighter and louder than traditional ferrite-loaded subwoofers. The hybrid design not only delivers deep, liquid lows but also ensures excellent transient response, making it ideal for high-impact, high-SPL performances.

The system's design and layout make it the perfect fit for a wide variety of applications. With a frequency response of 25 Hz to 90 Hz (+3 dB), the Kraken-MK3 is able to deliver incredibly low frequencies while still maintaining punch and clarity. It reaches a peak SPL of 148 dB, making it ideal for environments that demand high-output bass without distortion. The 360-degree dispersion ensures that the bass energy is evenly distributed across the entire venue, filling every corner with the same deep, resonant sound. Additionally, the Kraken-MK3 offers cardioid configurations when multiple units are used together, allowing for optimal low-frequency control and reducing rearward-facing energy for cleaner sound in specific applications.

To maintain full control over the Kraken-MK3's performance, it is equipped with an advanced integrated DSP (Digital Signal Processing) system. This DSP provides comprehensive control with high-pass and low-pass filters, equalization, phase alignment, and multi-stage limiting to ensure that the subwoofer operates within safe parameters. The DSP's sophisticated protection systems prevent thermal overload, excessive excursion, and clipping, while its multi-level limiting ensures that transient responses are preserved even at peak output levels. The Kraken-MK3 offers a total of 100 presets, with eight directly accessible at the push of a button, ensuring that you can tailor the system's performance to any environment or event.

The Kraken-MK3 is designed with ease of use and portability in mind. The cabinet is constructed from 18mm Baltic Birch plywood with extensive internal bracing, ensuring maximum strength and durability while minimizing unwanted resonance. The cabinet's rugged weatherproof polyurea coating ensures it is resistant to the elements, making it perfect for both outdoor and indoor events. The subwoofer is equipped with eight steel bar handles (two on each side) for easy transport, and the system features UHMWPE sliders on all four sides to facilitate secure stacking and transport. The interlocking feet and optional transport carts ensure that you can easily move multiple Kraken-MK3 units, with a truck-pack-friendly design that optimizes space for efficient transportation.

For ultimate convenience, the Kraken-MK3 includes the Neutrik powerCON True 1 TOP waterproof connectors, ensuring safe and reliable power connections for outdoor events. The XLR-M pass-through connector allows easy chaining of multiple units, and the two EtherCON RJ45 connectors provide LAN connectivity for remote control, monitoring, and firmware updates. This gives you full control over your subwoofer system, allowing you to manage multiple cabinets simultaneously, adjust levels, monitor performance, and apply presets directly from a computer.

With its ability to deliver deep, hard-hitting bass, extreme SPL, and exceptional clarity, the BASSBOSS Kraken-MK3 is the subwoofer of choice for professionals who need maximum impact without compromise. Whether you're driving an arena-wide system, creating an immersive sound experience at a festival, or adding the finishing touch to a high-end nightclub, the Kraken-MK3 will ensure that your audience feels every beat, every drop, and every note with incredible power and precision.
