DiaMon 112 Single 12″ Powered Top

How does so much sound
fit in here?!

Specs  |  Top




The DiaMon 112 is a very compact, high-output, self-powered loudspeaker. The DiaMon 112 can be used with up to two double 18” subwoofers for each cabinet, and deliver all the mid-high you need to keep up with them. As a DJ monitor it provides tight, punchy performance and doesn’t distort at extremely high levels.


Because the tweeter exits through the middle of the woofer, the extra area that the tweeter would ordinarily take up on the front of the loudspeaker is eliminated, which helps make the DiaMon extremely compact. It’s barely bigger than a 12” woofer but also incorporates a 1.4” exit compression driver with a 3” voice coil.

The DiaMon 112 includes a 1500-watt Class D Powersoft amplifier with built-in digital signal processing, is bi-amped and has a full complement of protections, limiters and equalizers that ensure consistent, accurate and reliable operation. It is fully self-contained and needs no more than power and signal to be ready to go.


Even though the box is very small and very lightweight, there is nothing small or lightweight about its performance. This box is literally packed with the best components and technology money can buy, the whole point of which is to do more with less. The output of this little box is totally out of proportion to its size. It’s extremely loud, but it’s capable of being loud, not struggling to be loud. It sounds much bigger than it looks and has the ability to maintain crystal clarity even at the upper limits of its very remarkable capabilities.

Just Add

The DiaMon 112 is a mid-high loudspeaker, so in order to deliver the BASSBOSS experience with full system sound it’s best to combine it with a very powerful BASSBOSS subwoofer. It has the output to keep up with several subs and for system usage is intended to be mounted on a pole-stand above one or more BASSBOSS subs. Used with a subwoofer system, the DiaMon is an extraordinarily size-conscious and yet very powerful main speaker.


Any speaker that has the tweeter horizontally or vertically offset from the mid-frequency driver produces very different response as one moves through its coverage area from the tweeter side to the woofer side. This is due to the different distances the sound has to travel to reach the ears.

Due to the co-axial construction the path length difference between lows and highs is the same in any direction, allowing extremely consistent off-axis response regardless of which direction you move away from directly on center.

I’m completely blown away!!

DJ Luke Hunter, Treehouse Miami

Okay the BASSBOSS subs have been impressive for several years now, but just heard the two DiaMon DJ112 Monitors during my set at Treehouse Miami and I’m completely blown away!!

The absolute best sound

John Kiousis, Kong’s Ultra Night Club

When only the absolute best sound with no compromise will do in your nightclub bassboss products are the Lambo of PA speakers and subs. Every single component in the construction of the product down to the amplifiers they use are all the best possible parts available. If you are serious about your sound, BASSBOSS.

Seriously kicked ass without any sweat broken

Glen Allan, Chaos System

Look… This “little” box will literally blast the crap out of your space. You’ve got 1500 watts of tuned power doing things your brain says aren’t possible. But that’s still because you haven’t got it.


The DiaMon 112 has a unique angle-cut corner that allows it to be placed on a table and used as a DJ monitor without pole mounting. It also has a securely attaching threaded pole-mounting system for when it is used attached to a socket-equipped BASSBOSS subwoofer or on a similarly equipped tripod stand. An adjustable mount bracket is also available for alternative placements and for permanent installations on walls or ceilings.


As a main speaker, the DiaMon 112 can be used with two double 18” subwoofers and deliver all the mid-high you need to keep up with them. As a DJ monitor it provides tight, punchy performance and doesn’t distort at high levels. As a live reinforcement speaker, this versatile box provides consistent sound quality over a wide dispersion pattern with excellent resistance to feedback.

True Specifications

BASSBOSS technical specs are based on measurements of continuous performance in normal usage. Other manufacturers may specify output based on calculations rather than measurements; measurements outside the operating bandwidth; or on ‘Burst’ or ‘Peak’ readings.

BASSBOSS specifications are conservative compared to most manufacturers. They reflect what the products will achieve, consistently, in the real world. Since the real world is where you’ll be using your gear.

Our proactive philosophy causes specifications to be subject to change whenever improvements are made.

*Peak output is calculated using “industry standard” techniques. These calculation methods create theoretical specifications that are inflated over what can actually be achieved. BASSBOSS real world output specifications are provided as “Maximum Sustained Output” ratings, which reflect actual measured, continuous output levels.

Deep Dive

Hand-Built Cabinets

The cabinets are constructed from 15mm Baltic Birch plywood, assembled using dado joints, screws and advanced composite adhesives. Stainless steel hardware secures the amplifier and pole sockets. The cabinet is finished in an extremely rugged, black polyurethane coating. The drivers are protected by a black powder-coated, perforated steel grill. A decorative aluminum faceplate is available in several designs. Customized grills are also an option.

The DiaMon 112 cabinet has 3 forward-facing ports that surround the driver for coherent low frequency output. One port is located at the top of the cabinet to allow the amplifier and driver heat to escape, with two more on either side to allow cool air to access the heat sink and amplifier. Together they provide superior flow-through cooling for the electronics. The cabinet is made of 15mm Baltic Birch and includes a standard 35mm pole socket that is set to the rear of the cabinet to promote a slight downward angle when the speaker is mounted on a pole.

The DiaMon 112 is a 2-way, active, powered and processed mid-high loudspeaker. The DiaMon 112 is a near-field to medium distance monitor with wide, uniform dispersion. The vented cabinet features a 12″ mid-bass driver with a 1.4″ throat co-axial high-frequency driver.

Intended to be used with subwoofers. It can be mounted on a pole above a subwoofer to perform as a DJ monitor or main speaker for portable applications and they can be mounted on walls and ceilings around dance floors for permanent installations. As a live reinforcement speaker, this versatile box provides consistent sound quality over a wide dispersion pattern with excellent resistance to feedback.

Optional Mounting Hardware. Mounting Brackets: Wall, Ceiling and Desk Mount options are available.

Prodigious Amplification

The DiaMon 112 is extremely compact, with a tremendous amount of power and output capacity jammed into a very small space. Almost the entire front surface of the loudspeaker is radiating area and the tiny enclosure houses a 1500W amplifier and a comprehensive DSP.

The amplifier consists of 2 channels with a total of 1500W. The amplifier features a universal automatic voltage selection, regulated switch mode power supply with Power Factor Correction along with a 0.5W standby current draw. It also provides superior control with a high damping of >10000:1 from the class D output topology.

The on-board DSP features high-pass and low pass filters, phase alignment processing, equalization and multiple limiter functions. There are 4 presets available within the DSP which allow the speaker to be tailored to suit the environment and application.

All the processing necessary for linear frequency response and phase coherent operation are pre-programmed into the DSP. With the comprehensive processing built in, BASSBOSS loudspeakers provide the ease of plug-and-play operation and the peace of mind that comes from knowing that the multiple limiter systems make to system virtually indestructible.

Rugged Drivers

Co-Axial driver, featuring a Neodymium motor structure for the highest efficiency to weight ratio. The LF and HF drivers share a common magnet structure to save space and weight and feature 3″ diameter voice coils. The HF compression driver exits through a 1.4″ diameter throat, down a machined aluminum horn, through an acoustically transparent dust cap. The coverage pattern is 80 degrees conical. The woofer coil is copper, and the compression driver voice coil is aluminum.

High-intensity Neodymium magnets are lighter to provide higher efficiency. The result is a lighter and louder cabinet. Co-axially aligned drivers allow the cabinet frontal area to be much smaller than a conventional loudspeaker to provide a more coherent acoustical point source, resulting in more consistent sound quality regardless of the listener’s position.

The cones are waterproofed to protect them from possible, accidental exposure to moisture such as rain or spilled beverages. Waterproofed woofer cones also permit the cleaning of drivers that have been soiled in a dirty or dusty environment with the use of a damp cloth. Keep the amplifiers dry and party on!

Waterproofed cones in all products. Optional weatherized and weather resistant loudspeakers have the same acoustical performance as our standard options. If your system is likely to be exposed to rain, ask about IP rated amplification options. If you have need of a system for outdoor installation, ask about Weatherized products.

Focused Tuning

BASSBOSS speakers can be connected directly to your mixer with nothing but signal cable in between. The built-in processing is comprehensive and includes all necessary high-pass and low-pass filters along with equalization and phase alignment processing to ensure coherent response when deployed with BASSBOSS subwoofers.

There is no need for any additional EQ in the signal path for the speaker to provide a broad, flat frequency response. Sophisticated DSP programming ensures the speakers deliver consistent sound quality no matter the input level.

Plug-and play with peace of mind. Multiple, sophisticated protection systems make the loudspeaker virtually indestructible. You can turn on and turn up, all night, without fear of over-driving to the point of damage.
