Deep Dive
Product = Primo

Why the AT212-MK3?

You do production for bands or DJ shows and your system needs to be easy to move, easy and fast to set up and unassailably capable. You need to play outside, or in big rooms, and you need a speaker that gets seriously loud. You can fly your tops when you need to extend your coverage. You've decided that the DV12 isn't quite loud enough for your needs. You need the next SPL step up… The AT212-MK3 is a top box. (AT stands for Attuned Top.)

It's way too capable in the mids and highs to be practical without a subwoofer. It goes low enough to provide good warmth and impact, but you're going to want subs with this one. Preferably 2 or 3, and not small ones, either. The AT312-MK3 is a multi-tool of a loudspeaker, with one replacing up to 3 seemingly competitive dual 12" tops. It's a road-warriors weapon of choice.

Put it with a set of SSP218-MK3 Subs and it can roll in on the subs, stand up and rock the house, then lie back down on the subs and roll out in virtually no time. It can also go up in the air, with rigging points on the top and bottom, allowing it to be flown vertically or horizontally. The horn is rotatable, so the coverage matches the application. With the horns rotated, the AT212-MK3s are arrayable, ideally in groups of 3, if you ever need to add more SPL to the mix. You may not need to given the SPL that just one is capable of, but it's nice to know you can...

Philosophy = Principled

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

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.

Craftsmanship = Consummate

Prodigious Power

The AT212-MK3 features 3200W of amplification. With 2400W of its power available for the woofers and 800W available to the tweeter, power is plentiful. The amp's high peak-output voltage provides for very intense, high SPL hits. 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, two 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 high-efficiency, neodymium motor, 12-inch woofers with 3.5-inch (88mm) voice coils and a compression driver with a 3-inch (76mm) voice coil mounted to a 1.4-inch (35mm) throat cast-aluminum constant directivity horn.

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've waterproofed our cones to withstand accidental exposure to moisture – whether it's an unexpected rain shower or a spilled drink.

Choice Cabinets

The AT212-MK3 is a 2-way, dual 12-inch self-powered, vented, direct-radiating full-range with a rotatable 80 x 60-degree constant directivity horn. The cabinet is built of 18mm and 15mm Birch plywood. It features an 18mm baffle, bottom and top. There are 4 steel bar handles, a 35mm pole socket, and 4 fly points. The horn is rotatable, providing 80 x 60-degree coverage for multiple applications including ground stack and vertical or horizontal flying.

Designed as part of a 3-way active full-range system, intended for use with a subwoofer. Its tall and slim design positions the HF horn above crowds when stacked on subs. Weighing just 89 lbs, the AT212-3K enables one person to set up a substantial system.

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.

MK3 = Monumental

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.
