BassBoss ZV28-MK3 Dual Active Subwoofer Speaker, 18"

Go low without limits! The BassBoss ZV28-MK3 dual active sub delivers extreme power handling with bass extension down to the lower limits of human hearing.

The ZV28-MK3 Dual 18" Active Subwoofer delivers a groundbreaking performance and ultra-low frequency response. Smooth, even, accurate, clean, super-high continuous deep bass output are the key attributes of this monster sub.

The ZV28-MK3 Subwoofer delivers bass so low as to be at the very limits of human hearing. Notes that are simply not present with other subwoofers are fully realized by the ZV28, and frequencies that stress lesser subs are reproduced effortlessly and powerfully. The ZV28-MK3 must be felt as well as heard to be truly appreciated.

For super-low modern bass music, just two cabinets will produce exceptional levels of extraordinarily deep bass. The ZV28 is designed to deliver an intensely physical experience for the audience. No other sub does what this one does.

The all MK3 series deliverers a suite of updates to the BASSBOSS line, improving clarity, performance, functionality, and safety via the updated amplifiers, DSP, custom control software, waterproof connectors, and more.

The updated amplifiers + DSP feature much more powerful 96 kHz processors with pristine sound quality and eight touch-of-a-button on board presets. This state-of-the-art Class D amplifier provides a true 5000 Watts of RMS power. The amplifier is truly capable of delivering continuous power, ensuring that it isn't the limiting factor on your quest for low frequency. Additionally, by providing an abundance of power, the possibility of overheating and damage to the woofers caused by read more clipping is virtually eliminated.

New "Control BASSBOSS" software provides additional computer-accessible presets, networked remote control, and future proofing remote DSP update capabilities as BASSBOSS programming is developed and released. Each unit features dual ethernet ports with a built-in network switch for computer connectivity and cascading networking ability.

IP65 waterproof connectors have been added to provide peace-of-mind in unpredictable environments, and the MK3 line offers 90-250VAC global power compatibility for use all over the world.

The first generation ZV28 was independently measured at Ultra Music Fest 2013 to achieve flat frequency response to 21Hz (-3 dB) at audience distance. A sub system of only sixteen ZV28 Subs and eight Z5/D Subwoofers was used to create a legendary gig for close to 10,000 screaming fans.

The ZV28 is a vented, direct radiating subwoofer with a large internal volume and a very low tuned frequency. Anti-standing wave baffles and pass-through dampers minimize upper resonances while very large ports maximize low frequency performance at high output.

The ZV28-MK3 is optimized for full-power operation. It is designed to thrive at full rated RMS power throughout its operating range while ensuring the woofers remain within their excursion and thermal limits. The ZV28 delivers consistently flat frequency response, and a pair delivers response that is -3dB at 21Hz. The ZV28's sensitivity is achieved and maintained through careful optimization, the use of premium components, prodigious power, and innovative DSP technologies, yielding massive low end on-demand. This legendary model is engineered to work hard and continue to work where others fail. With the peace of mind afforded by plentiful, clean, undistorted output and comprehensive protection systems, you can confidently push the ZV28-MK3 to levels and depths that are simply not attainable elsewhere.
