ZV28-MK3 Double 18″ Subwoofer

Why the ZV28-MK3?

The ZV28-MK3 goes deep. Deeper than most music. If you want to go deep, it's incredible! If your system isn't playing the deep notes that you know are there, or that you know should be there, then the ZV28-MK3 is here to fill the room with what you've been missing!

The ZV28-MK3 is on the cutting edge. No other manufacturer is making subs to satisfy that 1%. We believe that artists and producers will be inspired to incorporate more of these mind-melting frequencies when they know there is a system that has the ability to produce them, at scale, for large audiences with ease and power.

Deep. What does it mean? Why does it matter? It's really quite rare. But when you hear it for the first time…

Your smile grows right out of those lows. Deep inside you there's something that responds to those luscious, low frequencies. It's not an ordinary feeling. Once you've heard them, felt them, it's an addiction. You can't live without them. You can't have too much. It's thick, it's sick, it's trick. It's damn near magic.

If you don't know this experience, your life is incomplete. You need to experience a ZV28-MK3, or two, or ten. If you do know this experience, you probably have had at least one ZV28-MK3 somewhere in your life, but you want more… if you're smiling and nodding, the ZV28-MK3 is for you.

On the other hand, there are a lot of genres that don't need ZV28-MK3s, and there are applications in which the ZV28-MK3 is difficult to use. If what you do is primarily live bands with live drums, the ZV28-MK3 can create challenges. Due to their power at very low frequencies, infrasonic feedback is much more likely with ZV28-MK3s than other subs. Live kick drums produce massive transients at very low frequencies, so extra care has to be taken to prevent over-excursion with live drums. Even some electronic music genres just don't go that low, so having ZV28-MK3s for music like psy-trance isn't all that helpful. Oldies rock and 90s hip-hop also don't go that low. It's not the fault of the music, it's essentially the technological shortcomings of the equipment used to broadcast and play the music created in those times.

Although the number of releases with deep bass, at least deep enough to show off the ZV28-MK3s capabilities, is increasing, it's still a tiny fraction of the music in the world. Based on experience, maybe 1% of the music in the world includes frequencies that really make the ZV28-MK3 shine. Bear that in mind… but if deep bass is your jam. frequencies that push other systems to their limits are brought to life powerfully and smoothly. The ZV28-MK3 isn't just about hearing – it's about feeling the power of the music.

Straight Specs

At BASSBOSS we believe in power, precision, and practicality. While others in the industry may rely on theoretical calculations or skewed metrics, we provide real-world performance measurements. Performance claims that can't be met are worse than irrelevant, they are deceptive.

If you compare our specs to many in the loudspeaker industry, our specifications might seem rather unimpressive. That's certainly not because the products are underperforming, it's because we choose to tell you the truth instead of marketing hype. We bring you the reality of what our products can actually deliver in real-world conditions. We believe that should matter most to anyone who actually lives in the real world.

Many manipulate data in order to paint an exaggeratedly rosy picture of their products. Things like calculating peak output instead of measuring it, or quoting peak output figures based on output at frequencies outside the operational range of the loudspeaker, or quoting output that's achieved without the necessary processing having been applied. These methods churn out inflated specifications that don't match up to any actual, achievable levels. At BASSBOSS, we like to keep it real. We provide our “Maximum Measured Output" ratings, reporting the levels that we have actually measured our products reaching, and that's with all the filters and limiters in place, exactly the way you receive them. In our book, authenticity always wins.

Champion Components

Every single item in the BASSBOSS lineup echoes our unwavering dedication to superior quality. From the awe-inspiring capacity of our largest festival rigs to the compact portability of our smaller systems, each piece is crafted to meet the same standards, to be exceptional on its own merits. This guarantees that every beat you feel and every song you hear is delivered with the clarity, power and steadfast reliability that are the hallmarks of the BASSBOSS experience.

As part of our commitment to exceptional quality, BASSBOSS goes the extra mile to ensure the components we use are the very best in every application. The best, in this context, doesn't always mean the most exotic, the most expensive, or having the most impressive specifications. It means the best for that particular purpose. Factors like frequency response and efficiency have to be backed up with long-term consistency of performance, long-term reliability, and fitness for purpose. We source top-tier components, from the best-reputed suppliers in the industry, just like every other high-end loudspeaker manufacturer.

If there is a difference between BASSBOSS and the other buyers of these same premium components, it's in the expectations we have for our systems. We didn't grow up on rock-n-roll, we grew up in the age of electronic instruments, digital recordings and deep bass. The demand for more and more SPL at lower and lower frequencies isn't something we're trying to catch up with, it's something we've been leading for years. Those bigger competitors eventually try to build products to do what we do when the demand gets big enough for them to do it. Meanwhile, for years we've been building the products that created that demand. By the time you're able to buy anything similar from them, we're already making the next insanely powerful product they'll eventually try to compete with. They do say imitation is the sincerest form of flattery.

Deep Design

BASSBOSS is an investment into your creative identity. When you join the BASSBOSS Family you don't just get world-class audio equipment, you get something even more valuable: The BASSBOSS experience. Our products are designed for you to be able to make the most of them from the moment you take them out of the box.

Each element is purposefully crafted. Everything has a reason and a purpose, and that purpose is to make getting consistently great results easy and trouble-free. Whether you're a sound enthusiast or an audio professional, BASSBOSS lets you take control, effortlessly. To begin with, it's as simple as plug-and-play. No complicated setups, no fiddling around with complex controls. Connect directly to your mixer with just a signal cable, switch on, and the BASSBOSS experience means you're ready to deliver powerful soundscapes that move your audience.

Your sound, your way. Our Digital Signal Processing is comprehensive yet accessible. With a variety of inter-compatible presets and the ability to seamlessly switch between them, you can adjust and fine-tune your sound with just the touch of a button, or, if you prefer, the click of a mouse. Everything you need, nothing you don't. The integrated processing allows you to make changes so you can achieve the sound balance you want. And if you're wondering, no, it doesn't allow you to make changes that shouldn't be made, of the type that could cause damage or a deterioration of quality. One more benefit of the experience.

Prodigious Power

The ZV28-MK3 features 5000W of amplification, with an auto-sensing, globally compatible power supply that can run on input voltages anywhere between 90 and 250 Volts. Full output power is available on anything over 110V. The amplifier's peak-output voltage provides intense, high SPL hits while its sustained output is unparalleled in its ability to deliver the liquid lows. The amplifier is passively cooled via its external heat sink and by woofer-generated air flow through the port. When necessary, four blower fans will engage to provide additional forced-air cooling capacity in more extreme conditions.

Every BASSBOSS product comes equipped with amplification, and in every case, a generous supply of power is provided. Headroom is the term used to describe the power that's still available when the sound is at the level required, and the BASSBOSS amps provide ample headroom. While it's necessary to have limiters in the DSP to prevent driver overload, those limiters aren't there to prevent amplifier clipping. There is enough power in every product to reach its maximum SPL without the risk of clipping the amplifier.

In other words, the amplifier is never the bottleneck in delivering powerful low frequencies, dynamic impact and clear sound. This abundant power capacity not only keeps overheating at bay but also eliminates the potential for damage caused by clipping an underpowered amp. With BASSBOSS, you've got the power to keep your sound pumping.

Thumping Transducers

Amplifier power is converted into the much more desirable acoustical power by two robust, neodymium motor, 18-inch woofers with massive 4.5-inch (115mm) voice coils. Neodymium magnets are lighter, and their higher intensity provides higher efficiency, so the result is a lighter and louder cabinet than those with ferrite drivers. Our split-wound woofer coils create a more consistent force throughout the cone's range of movement, minimizing distortion and enhancing linearity at peak output.

The protection systems involve several techniques running simultaneously to effectively prevent thermal overload of the voice coils and limit excessive excursion. Reducing thermal saturation not only prevents burned voice coils, it also minimizes long-term thermal compression. Due to the sophistication of these multiple, independent yet simultaneous processes, the drivers can be protected while the actions of the limiters have virtually no noticeable effect on the transient response of the loudspeaker. Peak output can be achieved consistently, repeatedly and safely.

We understand that real-life situations can sometimes be messy. That's why we've waterproofed our cones to withstand accidental exposure to moisture – whether it's an unexpected rain shower or a spilled drink.

Choice Cabinets

The ZV28-MK3 is a vented, direct radiating subwoofer with a substantial internal volume, tuned to a low frequency. Advanced design features such as anti-standing wave baffles and pass-through dampers help reduce upper resonances while oversized ports enhance low-frequency performance at high output.

BASSBOSS cabinets are designed to endure for a very long time. Built from robust Birch plywood, our construction process involves precise dado joints, cleverly integrated bracing, and cutting-edge adhesives to create sturdy, rigid cabinets that stand the test of time. With a little care in handling, and especially with the use of the BASSBOSS carts and covers, BASSBOSS cabs can look new years down the line, even after many demanding environments and less-than-ideal locations.

The cabinets are protected by a rugged black polyurea coating that's specially formulated to bond to wood. Amplifiers are recessed into the back of the cabinets, safeguarding them from impact damage, with the cabinet recesses also functioning as structural braces. Powder-coated, perforated steel grilles protect the woofers. Every effort is made to create a physical enclosure that will stand up to whatever you throw at it, giving you years and years of solid service.
