BassBoss SUBLIM8-MK3-WHITE Class D 4000W Active Column Speaker System with 18" Subwoofer 133 dB - White

Redefine what a column speaker can do with the BassBoss SUBLIM8‑MK3-WHITE, engineered with a true 3‑way system, waterproof cones, and rugged birch construction for real‑world performance.

Introducing Sublim8 Column Loudspeaker
Your no-compromise solution for elegant form factor + intensely powerful sound.

Sleek Not Weak
The power and performance that columns always promised but never delivered. It's what column speakers always should've been. We call it the Column Crusher!

So Sexy So Stylish
Refined on the outside, rugged on the inside: Sublim8 is at home in elegant spaces but tough enough for touring. Waterproof cones, IP-rated connectors, and pro-grade DSP mean it's ready for anything.

Ready to Roll
Sublim8 comes with a fitted cover for each section and rolling cart, making setup and transport just as refined as the design. Quick load-ins, quick load-outs, and fewer headaches: built for working pros who need the best.

Light It Up!
Sublim8 provides power and mounting connections for a top-mounted light fixture, such as a small moving head or wash/derby fixture. This further simplifies setup and improves sightlines, removing the need for truss towers.

MK3 Amp Update
There are all-new amplifiers in the MK3 series. Total power has increased, however power allocated to woofers increased substantially. The higher output voltages provide more impact. Universal input voltage compatibility of 90-250V provides more flexibility. Waterproof connections provide more peace of mind.

MK3 Enhanced DSP
The MK3 features an all-new 96kHz DSP. The pushbutton presets have doubled, from 4 to 8, and up to 100 presets can now be stored in the DSP and loaded via LAN. The comprehensive suite of processing includes meticulously tuned equalization, all necessary high-pass and low-pass filters, as well as multiple protection systems and limiters to prevent driver overload in as many ways as possible.

ControlBASS Software
ControlBASS software supports an essentially unlimited number of possible BASSBOSS-developed or customized user presets which integrate seamlessly and coherently with all other BASSBOSS products for effortlessly perfect setups. The latest in DSP programming developments can be added via easy remote updating.

At BASSBOSS, with the MK3 line we have stopped using "Peak" and "RMS" power ratings for our amplifiers because those numbers alone are not an accurate representation of the real-world performance you can expect from our powered loudspeaker systems.
Peak Watts:
Essentially a theoretical maximum that the amplifiers could output for an instantaneous moment under ideal conditions with no load.
However, this peak power is not sustainable and has little practical relevance for how the loudspeakers will actually perform.

RMS (root mean square) Watts:
A measure of continuous power output, but even this figure doesn't account for the true efficiency of how that power is converted into acoustic output by the transducers and overall speaker design.
The number of watts a loudspeaker "uses" is constantly fluctuating based on the impedance curve, frequency response, and heat generated in the voice coils.
Simply looking at how many watts an amplifier can produce on a test bench doesn't translate to its real-world sound output capability.

What matters most is the complete integrated loudspeaker system and how efficiently it can convert the amplifier's power into acoustic output while maintaining flat frequency response and headroom. Two loudspeakers with the same wattage ratings could have vastly different real-world sound pressure levels and clarity.

For these reasons, we believe wattage ratings alone are not a reliable metric. Listening tests and measurements of the overall system's output capabilities like maximum SPL and distortion are far more telling than any peak or RMS wattage number viewed in isolation.

Our goal is to provide outstanding performance through intelligent system design, not just big wattage numbers.

Why the Sublim8?
Column speakers have always been about convenience-quick setup, sleek looks, easy coverage. But for working DJs, musicians, and venues, they've just as often meant compromise: thin sound, weak bass, and limited power. At BASSBOSS, compromise has never been part of the equation. That's why we didn't release a column until we could build one that felt complete-deep bass, full-range clarity, pro-grade components, and rugged build quality.

The result is Sublim8: the Column Crusher. Designed for real gigs, not just background music. With the same engineering DNA as our flagship systems, Sublim8 delivers the power and performance that columns always promised but never delivered.

At BASSBOSS, form always follows function-but function doesn't mean fugly. The challenge was to create something that sounds huge, handles like pro gear, and still looks like it belongs at a luxury event. Sublim8 was born from that challenge. Designed for real-world working conditions, it was engineered with the same obsession as every BASSBOSS product, with professional-grade components, rugged birch construction, no cable spaghetti issues, and a super-high power Class D internal 4000W amplifier. Sublim8 is a true 3-way system with an 18" subwoofer that covers large audiences and dance floors with ease.

Whether you're a mobile DJ tired of settling, an AV provider looking for a scalable system, or just someone who wants full-range sound without the bulk, Sublim8 brings you the BASSBOSS standard in a new form factor.

Do You Really Need Extra Subs?
When it comes to column speakers, the usual answer is yes-if you want any kind of bass, you're expected to haul along a separate subwoofer (or two). Most columns are slim, lightweight, and easy to carry, but they sacrifice the very foundation of music: low frequencies. That's where the BASSBOSS Sublim8 changes the conversation.

Rethinking What a Column Can Do
Sublim8 isn't designed to be "just enough" for background music. It was engineered to produce full, rich sound with deep low-end extension that most columns simply can't touch. That means for many gigs, you don't need to bring an extra sub at all: the Sublim8 delivers a complete, satisfying sound on its own.

Musicians hear the warmth of their instruments carried with clarity. DJs get the punch and depth to keep people moving without worrying about whether the bass will disappear. Venues and event spaces can offer clear, full-range sound without cluttering the floor with bulky extra boxes.

When You Might Want More
Of course, there are moments where more really is more. If you're playing a larger outdoor space, hosting a high-energy DJ set, or want to create a festival-level experience, adding BASSBOSS subwoofers will take things from impressive to unforgettable. The beauty of Sublim8 is that it's ready to scale-presets and alignment are already built in, so integrating subs is seamless.

The Value of Complete Sound
Every extra box means more to buy, more to carry, more to set up. By delivering deep bass on its own, Sublim8 saves time, money, and space-without forcing you to compromise. You get professional-grade sound that feels bigger than the system itself. And when you decide to expand, it grows with you.

The Bottom Line
So do you really need extra subs? With most column systems, the answer is always yes. With Sublim8, the answer is no-unless you want to. If you do want more low end power, Sublim8 is more than capable of hanging with multiple additional subwoofers without breaking a sweat.

Sublim8 stands apart as the Column Crusher, delivering low end you can feel, clarity that carries, reliabiltiy you can trust, and flexibility that lets you choose how far you want to go.

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
Sublim8 features 4000W of amplification. With 2400W available for the sub, 800W for the mids, and 800W on the highs, power is plentiful. An auto-sensing, globally compatible power supply that can run on input voltages anywhere between 90 and 250 Volts ensure it can work wherever you take it. Full output power is available on anything over 110V. The amplifier is passively cooled via its external heat-sink and by woofer-generated air-flow through the port. When necessary, a blower-fan 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 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 their 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 1 x 18 in. diameter (450mm) neodymium motor woofer with 4 in. (100mm) voice coil, waterproof cone 2 x 8" diameter (210mm) neodymium motor woofers with dual 2" (51mm) voice coils and waterproof cones 1 x 3 in. (76mm) diameter diaphragm compression driver with 1.4" (35mm) exit mounted to isophasic wave guide. 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.

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 use waterproof cones to withstand accidental exposure to moisture - whether it's an unexpected rain shower or a spilled drink.

Choice Cabinets
Sublim8 is a 3-way full-range loudspeaker system with vented direct radiator subwoofer cabinet, a vented direct radiator mid-bass cabinet with Isophasic waveguide loaded in the high frequency section and an interlocking spacer. The amplifier offers abundant headroom and the proprietary BASSBOSS processing ensures exceptional sound quality and reliability.

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 covers, BASSBOSS cabs can look new years down the line, even after being in 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.

Processing Perfection
Proprietary DSP design techniques are at the core of the BASSBOSS line. Every BASSBOSS product features dedicated and integrated signal processing. Proprietary measurement and processing systems allow BASSBOSS products to deliver superior performance and value compared to others of similar size, price or coverage. The innovative, sophisticated protection in the DSP allows the drivers to run louder and longer and remain reliable. The nature of the processing, along with the proprietary limiters, allows the speakers to maintain their character and sound quality to a level higher than you might believe possible.

The protection systems involve several techniques running simultaneously to effectively prevent thermal overload of the voice coils and limit excessive excursion. 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. Reducing thermal saturation not only prevents burned voice coils, it also minimizes long-term thermal compression. Peak output can be achieved consistently, repeatedly and safely.

Insane Improvements
The MK3 series, available now, brings an upgraded DSP with an immense boost in processing power. Operating at a sampling rate of 96kHz, it delivers double the resolution of its predecessors, resulting in increased fidelity and a lower noise floor.

The MK3 series doesn't stop there. It provides you with eight meticulously tailored preset alignments, all readily available at the click of a button. Further improving your user experience, the system now enables immediate preset switching with zero signal dropouts, ensuring smooth transitions even if you choose to make preset changes during performances.

This is where excellence meets simplicity: our systems can be connected directly to your mixer, requiring nothing more than a signal cable for you to have all the control you need to achieve great sound. The eight directly accessible presets are compatible with all the presets in all MK3 Boxes and are also compatible with previous generation tops and subs.

For those who need more control, there is more available.

Functionality Fortified
The new DSP features an Ethernet interface. Connecting via the ControlBASS software offers remote control and monitoring from a computer, and allows access to essentially unlimited presets through updates and new releases. With a computer connected, the MK3 DSP features access to a storage capacity of up to 100 on-board presets.

Within the software, multiple cabinets can be grouped together, allowing them to respond to commands simultaneously. This permits the levels of multiple loudspeakers to be adjusted together, and yet independently from the levels of other groups of loudspeakers. In addition to individual and grouped level controls, presets can be loaded and signal levels and temperatures can be monitored.

The MK3 series further expands its functionality with an integrated 2-port network switch, enabling cascaded LAN configurations to easily group loudspeakers for centralized control, making the MK3 series the ultimate tool for taking the reins of your sound experience.

Our systems are designed to grow with you. Want to add more BASSBOSS products to your setup? With inter-compatible tops and subs, cascading LAN configurations, network switches and ControlBASS software, expansion is a breeze. System simplicity, scalability, and sonic excellence: The experience becomes yours.
