Just wanted to let you know that we received the speakers this past Friday and everyone is thrilled. The AT312s are amazing. We did an A/B comparison test outside against 6 QSC KLA 12″ line array cabs and the 312’s blew them away.
OMG… I never thought there would be such efficient speaker systems available. What incredible sound! The kids love the bass because they can FEEL the music. BASSBOSS has made such a difference to our students.

All the Advantages

By building a speaker that's as close as possible to the theoretical ideal of a single, infinitely small point, the AT312 offers resolution and imaging that will fool your senses. So real you'll look behind you. So detailed you'll cry. So powerful you'll need to share.

Just add Subs

Deep Dive
Product = Primo

Why the AT312-MK3?

You're not one to compromise. These are the tops with the name drops that are so big, we simply can't drop them. (??) These are the tops that can compete with the best in home hi-fi for sound quality, then leave them in the dust and smoke when the levels rise. These are the tops you buy to impress, well, pretty much anyone with ears. These are the tops you buy to spoil yourself. But be careful because they will spoil you. You'll miss them every time you hear music on anything else.

There are reasons not to buy them, of course. They aren't arrayable. They aren't the loudest speakers ever made. They aren't light. They aren't "long throw". They aren't cheap. If you want the ultimate monitors in your studio or in your DJ booth, yes. If you want the most pristinely perfect sound on your dance floor, yes. If you love to respect every little detail in every production you listen to, yes. If you want to provide your audiences with these experiences because you love them, or just because you can, yes.

AT312-MK3 Tops with ZV28-MK3 Subs are a sublime combination. Just keep that in mind.

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

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.

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.

Craftsmanship = Consummate

Prodigious Power

The AT312-MK3 features 4000W of amplification. With 2400W of of its power available for the woofers, 800W available to the midrange 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 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 two substantial, neodymium motor, 12-inch woofers with 4-inch (100mm) voice coils, a 12" neodymium motor midrange driver with a 3.5" (88mm) voice coil and, on the same neodymium motor, a compression driver with a 3" (76mm) voice coil that exits through the center of the midrange, which features a 1.4" throat machined aluminum conical wave-guide as its pole-piece.  

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. Its driver complement incorporates dual 12-inch woofers in a vented enclosure for low frequencies and a 12-inch midrange driver in a sealed enclosure with a co-axially mounted 1.4-inch exit compression driver. Coverage is 80 degrees conical. Dual 12-inch low frequency drivers were chosen to minimize cabinet frontal area while delivering the best possible speed and impact in their operating range. Thanks to the narrow frontal area, the low frequency drivers couple coherently when multiple cabinets are arrayed, providing powerful mid-bass impact from a small, lightweight box. The 12-inch coaxial drivers also serve to minimize frontal area while maximizing output. The 48 inch tall box elevates the mid and high frequency radiators to a minimum of 7 feet 6 inches on center when stacked on the corresponding subwoofer systems.

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 AT312-MK3 is a 3-way, Triple 12" Self-powered, Direct-radiating Full-range. The dual 12" low-frequency section is vented. The 12" co-axial mid and high section is loaded into a separate sealed chamber.

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.
