The BASSBOSS ZV28-MKII 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-MKII, and frequencies that stress lesser subs are reproduced effortlessly and powerfully.

Highest Standards

For super-low modern bass music, just two cabinets will produce exceptional levels of extraordinarily deep bass. The ZV28-MKII is designed to deliver an intensely physical experience for the audience. No other manufacturer produces a sub as powerful and low as the ZV28-MKII at a similar price point and physical size.

Lowest Frequencies

Experience full, rich sound that redefines what music can feel like. The ZV28-MKII makes modern dance music come alive by faithfully reproducing the very low frequency material that is not heard with other subs.


Includes a 4000W amplifier with integrated, comprehensive DSP. The ZV28-MKIIs are vented, direct radiating subwoofers 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. Protection systems and limiters control all manners of overload, including thermal, excursion and clipping.

Full Power

The ZV28-MKII is optimized for full-power operation. It is designed to operate at full rated RMS power throughout its operating range while ensuring the woofers remain within their excursion and thermal limits.The ZV28-MKII delivers consistently flat frequency response, and a pair delivers response that is -3dB at 21 Hz. No equalization is required to achieve this response and it is available at high levels in real world applications, continuously.

The ZV28-MKII’s sensitivity is achieved and maintained though careful optimization, the use of premium components and innovative, proprietary thermal management techniques. Thanks to the deep-bass sensitivity, the robust components and the prodigious power, massive low end is delivered on demand.

No Paper Tiger

The ZV28-MKII is not a paper tiger. Other subwoofers can be made to look similar on paper, but come up short in the field. Beware of loudspeaker systems that require processing to achieve their claimed frequency response. Those systems are still subject to the excursion and thermal limits of their drivers. Boosting low frequency EQ to achieve extended low-frequency response on specification charts isn’t the way to deliver superior results at maximum power. In fact, boosting low frequency EQ is likely to result in excessive distortion or woofer damage at full power. Under those circumstances the system cannot be utilized at full power. If limiting is applied to avert such failure, that limiting prevents the realization of the claimed frequency response at full power.

Will Not Fail

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-MKII to levels and depths that would require more or bigger cabinets from other manufacturers.
