This high-output Dual-21" Powered Subwoofer delivers deep, intense, bass, thrilling all of your senses in its connection of auditory and physical immersion.
The MAKARA shares much of its DNA with the mighty KRAKEN. For audiences who have never heard notes this deep, the experience is unforgettable and instantly addictive. Like the Kraken, the Makara not only goes deep, it also administers a fearsome impact delivered by the short-horn loading of the fronts of the cones.
This legendary creature achieves an enormous max sustained output of 140 dB SPL at 1 meter in a half-space (ground plane) environment, with a peak SPL of 143 dB, and a +/-3 dB Frequency Response of 23 Hz to 110Hz*.
With 5,000 Watts of power on tap, derived from two onboard discrete 2500 Watt Class-D global power amplifiers, the Makara ensures robust and reliable performance.
Its integrated comprehensive DSP provides high-pass filters, low-pass filters, equalization, phase alignment, cardioid processing, and multi-stage limiting for precise sound management. A cardioid mode is available to provide directional control when multiple cabinets are appropriately arrayed.
The 18mm Marine Grade Birch enclosure uses dado joinery and is extensively braced for the utmost strength and durability. Its black, textured, bonded, high-pressure polyurea coating is weatherproof, making it suitable for any environment. 35mm pole sockets are provided on all 4 sides. Equipped with four steel bar handles and UHMWPE strips as sliders/feet, the Makara is designed for easy transport and stable setup. The Makara sliders interlock with each other, and with the Kraken, providing the ideal building blocks for a "wall of bass".
The Makara is the latest embodiment of BASSBOSS's commitment to facilitating unforgettable experiences through powerful products.
