Stage, Lights & Sound
I have been using Meyer Sound for years. I was at a festival and a friend of mine was running the BASSBOSS Subs. I was floored by the sound levels BASSBOSS was able to achieve using half of the number of cabinets. From that point on, I switched to BASSBOSS!
We are very satisfied with the new BASSBOSS system! It’s well worth the money. The sound is so clear. I highly recommend them to anyone! You will be 100% satisfied!!!
We love these subs! they sound and feel so good. 0 complaints. We got a lot of compliments from members of the church. We’re happy with our purchase. Thank you for all the support!

Tight Tasty

The same big voice coils and big power amps used in the SSP218s, along with large internal volume and deep tuning, providing massive output at and above 35Hz, allow the SSP215-MK3 to comfortably take the place of double 18” boxes without giving up output or low-frequency extension.

Make it Rain

A double-15" subwoofer cabinet made to go head-to-head with double 18" subs, this low-profile option has 5000W of amplification driving the woofers and a premium-grade DSP providing control and alignment. If 215 wasn't in the name, you'd never know it didn't have bigger drivers.

Deep Dive
Product = Primo

Why the SSP215-MK3?

You need something special. You need all the bass from much less space. Maybe someone didn't leave enough room for double-18-inch subwoofers, but the room needs the output of double 18-inch subwoofers. Maybe you need to hide a subwoofer somewhere unexpected. Maybe you prefer the sound of 15-inch woofers.

Whatever the reason, the SSP215-MK3 is the antidote to compromise. It's seriously capable, genuinely competitive with the best of double-18-inch subs, but it's got that something special in that it's skinny. It will go under, over or between things that nothing with an 18-inch woofer can go under, over or between. And then there's the tricky part: the folks who prefer the sound of 15-inch woofers might be right.

The SSP215-MK3 does not need to have any excuses made about it or for it. It is something special. The SSP215-MK3 can fit under low stages, be flown in low ceilings and can be tucked in corners or between furniture where larger boxes would not fit. It's 29.5 inches deep, making it a perfect truck-pack size, especially considering up to 6 cabinets can be transported on a single rolling cart. Its largest dimension is 48 inches, so when stood up it can serve as a stack platform for getting the top boxes up above the audiences' heads, just like a double 18-inch sub. The smallest frontal dimension is only 17.5 inches, allowing lots of placement options. For venues, the low-profile box can fit under stages that are too low to accommodate a double-18-inch subwoofer, and yet it can easily power packed dance floors with deep and punchy bass.

The SSP215-MK3 puts tremendous power and deep tuning behind 15” cones to provide the best combination of tight punch and extended depth from a compact cabinet. The result is a 15-inch based subwoofer with the versatility required to translate the power of dance tracks, modern country, blues, rock, R&B and hip-hop with amazing presence and heavyweight power.

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 SSP215-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 continuous output is unparalleled in its ability to deliver sustained 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 heavy-duty neodymium motor, 15-inch woofers with 4-inch (100mm) 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 combination of extremely rugged, very high power handling, long excursion drivers, carefully optimized cabinet and port design and several effective but transparent protection systems allow this double 15” subwoofer to provide output levels and depths that compete with bigger, bulkier and far less articulate double 18” subwoofers. The protection systems effectively prevent thermal overload of the voice coils and minimize long-term thermal compression whilst having virtually no effect on the transient response and peak output of the loudspeakers.

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 SSP215-MK3 is a vented, direct radiating subwoofer, optimally tuned to provide flat frequency response to 35Hz with high sensitivity. The cabinet is extensively braced and rigid. The extremely low-profile SSP215-MK3 is particularly well-suited to deployment in tight spaces where suitably performing 8-inch cabinets won't fit. Below, above and between are words used in conjunction with the SSP215-MK3. Its performance is above that of most double 18-inch subs. Its response goes below most double-18-inch woofers. It can usually fit between the floor and the stage, between the rafters in the ceiling or between architecture and the furniture.

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.

With a top-mounted pole socket, the SSP215-MK3 provides for mid-high loudspeakers to be mounted on a straight speaker pole above the subwoofer. The enclosures also feature four large rubber feet and corresponding recesses in their tops to facilitate interlocking the boxes with each other and with the SSP218s when stacked. The feet also interlock with the transport carts, which helps to ensure that the cabinets get into and out of venues safely and unscathed. The woofers are protected by a powder-coated, perforated steel grille.

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.
