The SV9 and BB15 are perfect. I kid you not the club owner was upset that the sound in the small room was much better his main room. By a mile... People kept walking in asking what type of speakers they were. I can tell you those little tops are very capable for smaller spaces. 250 people or less depending on the location. For the first time in a while my ears were not ringing after a long night.

Danny Gee

This evening we are sporting the SV9 Tops and BB15 subs. Killer combo that leaves a small footprint and plenty of punch - Highly recommend.

I am so impressed by the clarity. It is a whole other class of sound, compared to the speakers I originally intended to buy. It also has an even more compact and light form factor. The sound is so balanced and so clear. It reminds me of the first time I put on a pair of high-end headphones. It’s like being transported into the music.

Load In Bliss

We had a woofer custom-made with a carbon-fiber cone, rubber surround, and a big voice coil. We designed a special, rock-solid wooden cabinet around it. We put top-of-the-line processing and amplification in it and tuned it for reference-grade response.

Premium Everything

It's either a reference monitor you can take on the road or an ultra-compact production speaker that you can use as a reference monitor. Either way, it's a pleasure to listen to, hour after hour, and a pleasure to carry when you have to move the music.

Deep Dive
Product = Primo

Why the SV9-MK3?

The SV9-MK3 is a two-for-one deal. It provides studio-monitor performance that you can take out of the studio. This lets you do things a studio monitor can't do in terms of output power and portability. It also lets you do things you wouldn't want to do with an ordinary PA speaker, like using them for reference or just listening to music for the pleasure of it.

You can use these for studio monitors and trust what you hear. Have you ever wanted a set of studio monitors that are extremely accurate as well as dynamic? The SV9-MK3 can do that. Have you ever wanted just a little bit more volume out of your studio monitors? How about a lot more? The SV9-MK3s can do that. When you want to show off a track to a friend, or a whole bunch of friends, you want them to hear it with the same quality that you experience in the studio. The SV9-MK3s can do that.

Have you ever wished you could find a small speaker that's easy to carry and gets loud enough to do gigs? The SV9-MK3 can do that. Have you ever wished you could get more SPL out of a top box when you add a sub? The SV9-MK3 can do that.

Ideal for smaller parties and events, the SV9-MK3 provides surprising output for its size and weight, making it the perfect option when you don't want to lug a large, heavy system. The SV9-MK3 can do a lot of different things, and, whether you use all their capabilities or not, it's nice to know you can.

If you need something that can put out more SPL, the next thing to look at is the DiaMon-MK3.

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. 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.

Craftsmanship = Consummate

Prodigious Power

The SV9-MK3 features 1200W of amplification. With 800W of of its power available for the woofer and 400W available to the tweeter, 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 a neodymium motor, 9-inch woofer with a 2.5-inch (64mm) voice coil and a compression driver with a 1.5-inch (38mm) voice coil mounted to a 1-inch (25mm) throat 90 x 60 degree 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 use waterproof cones to withstand accidental exposure to moisture – whether it's an unexpected rain shower or a spilled drink.

Choice Cabinets

The SV9-MK3 is a 2-way, single 9-inch self-powered, vented, direct-radiating full-range that can be carried in one hand.The Birch plywood enclosure is strong and solid but very easily portable. The 9-inch woofer features a large voice coil and a rubber surround for high power handling and smooth response. 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.

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.
