4,000 watts of Class-D amplification and response down to an astounding 21Hz.

The BASSBOSS ZV28-MKII Dual 18" 4,000W powered subwoofer is the flagship of the BASSBOSS sub lineup. It produces the kind of ultra-deep, low-frequency reproduction that must be experienced to be appreciated. It embodies the BASSBOSS mantra of "music made physical," and will redefine what you expect from a live sound PA system.

Thanks to the ZV28-MKII's potent 4,000W RMS Class-D power module and built-in DSP, robust dual 18″ drivers create a physical connection between the audience and the music and reveal low notes that other subs simply can't reproduce. Once you've heard the ZV28 sub in action—especially in conjunction with multiple units—you'll experience live sound reinforcement in a way you never imagined.

The ZV28-MKII is a vented, direct-radiating dual 18″ subwoofer with a large internal volume, extensive bracing and a very low-tuned frequency. Anti-standing wave baffles and pass-through dampers minimize upper resonances. Very large ports maximize low frequency performance at high output.

For larger events, several arraying options are available with the ZV28. Block arrays, side-by-side arrays and front/back Cardioid arrays can be deployed securely thanks to the interlocking feet. Presets are accessed in the DSP.

BASSBOSS was born out of a passion for ultra-deep low-end, and a belief that tight, clean, accurate bass is the foundation of great sound. Each BASSBOSS product is a mindfully engineered, painstakingly tuned, completely integrated audio system, intended to seamlessly pair with other BASSBOSS products. BASSBOSS speakers are designed, built and hand-assembled in America, using only premium components. Like its siblings in the BASSBOSS lineup, the ZV28-MKII powered subwoofer is optimized for full-power usage. That is to say, it's intended to be pushed hard and abused, gig after gig. So, don't hold back—crank it up.

BASSBOSS uses only continuous RMS power ratings because you’re not going to be using your sub in millisecond bursts. For subwoofer applications, peak and burst power ratings are largely irrelevant. 4,000W of continuous power with integrated, comprehensive DSP ensures the amp isn’t the limiting factor in the output of low frequencies, and prevents overheating issues and virtually eliminates the damage that clipping an underpowered amp can cause. BASSBOSS specs reflect what the products will achieve, consistently, in the real world—since the real world is where you’ll be using your gear.

Built to withstand the rigors of repeated gigging, the ZV28-MKII powered subwoofer is constructed from 18 mm Baltic Birch plywood, using dado joints, screws and advanced composite adhesives. Stainless steel bolts are used to secure the driver, amplifier and pole sockets. The cabinet is finished in an extremely rugged, black polyurethane coating. The ZV28-MKII's driver is protected by a black powder-coated, perforated steel grill, and the amp is recessed into the back of the cabinet for protection from damage.

When compromise is not an option, BASSBOSS has you covered. BASSBOSS refuses to cut corners or settle for less, and neither should you. If you've been looking for a subwoofer to give your sound system an edge over the competition—one that will help your nightclub, venue, or event production company establish a reputation for impeccable sound—look no further.
