Hyphn is a peerless, definitive, uncompromising demonstration of the Monitor Audio Group’s current design, engineering, and manufacturing capabilities, and its future ambitions. It is unlike anything Monitor Audio, or anyone else, has ever created: the most creatively ambitious, technically advanced, and powerful loudspeaker in the company’s history. It delivers a dramatically enhanced listening experience, with a visually striking presence.

This article is on the flagship Hyphn Reference Floorstanding Loudspeaker from our friends at Monitor Audio. Monitor Audio developed the Hyphn to celebrate their 50th anniversary in 2023. These were first shown at the 2021 Munich HiFi show as a prototype they initially called the Concept 50. With some feedback from listeners at that show, they made some small tweaks and changed the name to the Hyphn. Audio Advice Live, our annual audio and home theater show, hosted the first United States public demonstrations of this amazing loudspeaker.

Monitor Audio Hyphn Floorstanding Speakers

Company History

Monitor Audio was founded way back in 1972 just outside of Cambridge, England. Interestingly, many long-lived British audio companies were founded around that time and in a similar location. They have since moved to a town called Rayleigh, which is a short ride east of London near Britain’s east coast.

Hyphn Concept

The planning for this very unique speaker design started several years ago. Monitor Audio is a privately owned company, which meant the owners could give the engineers and designers free reign over their 50th anniversary creation and not have to worry too much about the cost. We spent some time with their industrial designer from the UK at Audio Advice Live and he told us, management told them to make the best speaker they could. When they started looking at other anniversary celebration speakers, they noticed a lot of them went back to a vintage design to celebrate the history of the company. Their design team wanted to go in an entirely different direction, as they didn’t want to have any constraints on the design by trying to make it look like Monitor Audio speakers of the past. The goal was to make the best speaker they could and to think about how speaker design might evolve in the future.

Hyphn Technology

When you see the Hyphn for the first time there is no question that these are like no other speakers we have ever seen. And then when we heard them on some of our favorite tracks, even in a show environment, we could tell, these were world class speakers. The Hyphn is made up of two towers with an array in the center called their M-Array. Monitor Audio starts with a solid surface material that is a composite of acrylic, minerals, and natural pigments. This acrylic stone material is then machine cut and hand polished to achieve the unique shape that supports the Hyphn’s components. While this creates a cabinet that weighs 235 pounds and stands 55” tall, the material is so rigid and inert, there are no unwanted vibrations.


We’ve said this before in a lot of our speaker overviews, that many engineers believe the ideal speaker would be a perfect point source but also have controlled directivity. This, in theory, would give you the most realistic three-dimensional sound stage possible. The M-Array uses a single third-generation MPD tweeter surrounded by 6 third generation RDT midrange drivers. That is certainly a mouthful of part numbers, so let's unpack exactly what the M-Array consists of. Monitor Audio has been using a Micro Pleated Diaphragm for many years. This design harkens back to the AMT tweeters made famous by Dr Heil but with many improvements. It has the appearance of a flat diaphragm with tiny pleats in it. This new third generation of the MPD tweeter extends out to 60,000 Hz and has less distortion than the previous model. The MPD tweeter is surrounded by 6 small RDT flat diaphragm midrange drivers. These are only 2” in diameter, but combined give you much more surface area than a typical single midrange driver.

The way they are arranged around the tweeter gives you that point source that Monitor Audio was after. These are no ordinary small drivers either. RDT stands for Rigid Diaphragm Technology used to create a composite ‘sandwich’ structure made from ultra-thin low-mass skins, bonded to a honeycomb Nomex® core material. Extremely light and strong, it can respond with great speed without bending. This combination reduces distortion by over 8 dB above 300 Hz, which makes RDT the lowest distortion cone technology in Monitor Audio’s history. And they are very wide range in response allowing them to cross the tweeter over higher for a better transition to the tweeter.

These all sit on a very cool-looking aluminum baffle right in the center of the Hyphn and at what will be most listeners' ear height. The arrangement to handle the lower frequencies is equally unique in the Hyphn.

Unique Bass Driver Configuration

The Monitor Audio team designed new bass drivers with four of them used directly behind the M-Array that couples the two cabinets together. Two pairs of 8” woofers face each other in a force-canceling design and are bridged together. Having these directly behind the M-Array contributes even more to a point source effect. Their in-room response is a very impressive 18 Hz at minus 6 dB.

And not only does it make the Hyphn more of a point source, it greatly improves its appearance in the room. Rather than seeing 4 large woofers facing forward, they are hidden behind the M-Array so visually you are struck with the beautiful contemporary design of the cabinet.

Hyphn Finish Option

Anyone lucky enough to purchase a pair of Hyphns will then have to decide on three beautiful finish options. These come in a striking white, black, or green finish. We hope Monitor Audio will offer even more color options in the future as these are quite the statement piece and more choices would allow them to fit into even more environments.

Monitor Audio Hyphn Finish Colors


We sat down and spent some time with these at Audio Advice Live. They were being driven by a Mark Levinson stack using their 50th Anniversary ML-50 mono power amps. These amps put out 850 watts each into the Hyphns 4 ohm load. This is the only disadvantage we see to the Hyphn. You will need lots and lots of power to wake them up. Their sensitivity is rated at 86 dB, and the engineers told us they recommend power amps up to 1,600 watts per channel.

After spending a few minutes going through some of our favorite test tracks, we have to say, Monitor Audio has produced one of the best speakers we have ever heard. The soundstage is incredibly wide and accurate with the speakers just completely disappearing. When you are in the center sweet spot, the stage they paint is just stunning. We’ve heard speakers with a taller stage, but these have an uncanny ability to place instruments in a 3-dimensional field that feels like it's about 5’ tall and extends far beyond the sides of the speakers. Vocals and strings sounded totally effortless and just floated with no sense of strain at all. And you could tell with percussive cymbal attacks, the top end flowed with ease. Bass was fast, tight, deep, and fully integrated with the upper frequencies. You could tell the huge room they were in at the show was holding back the deep bass attack a bit, but in a normal room, that aspect should be just awesome.

Overall Recommendation

No speaker is perfect and they all have some compromises. Monitor Audio has totally delivered the best speaker the company has ever produced and by a very wide margin. These are just spectacular. Are they inexpensive, no. Are they easy to drive, no. Do they weigh more than a refrigerator, yes. But if you can get past those points and set up a pair of Hyphns in your system, you will know what we mean when we say these are some of the best speakers in the world today.

Details & Specs

Hyphn Is A Statement Of Intent

Born Of Passion, Vision, & Knowledge

Hyphn is born of collaboration between Monitor Audio's designers and engineers, who set out to build the best loudspeaker anyone has ever heard. An ambition that’s easy to express, but a lot more challenging to achieve.

Hyphn is intended to be a ‘statement loudspeaker’ both technically and visually. It is also designed for ‘real’ rooms, taking into account and addressing all the inherent constraints and compromises that entails.

Achieved Through An Inherent Understanding of Sound

Hyphn is the more refined, further enhanced production version of the Concept 50 loudspeaker, unveiled to enormous media attention and universal acclaim in 2022.

Hyphn is a unique loudspeaker, created at a particular point in time through a combination of three specific factors: a deep understanding of the science of how we hear sound; solid engineering principles; and the creative freedom that comes with being an independent business.

Transparent Design Philosophy

Hyphn is a product of Monitor Audio’s Transparent Design Philosophy.

They believe the ultimate loudspeaker is capable of producing sound as laid down by the artist so accurately that it becomes transparent. The physical design should be sympathetic to this in any environment and work in harmony with the desire for transparency.

Hyphn is built upon an R&D philosophy of maintaining a balance between design and technology. One is never allowed to overpower the other and both play a vital role in delivering on the promise of musical neutrality and acoustic transparency.

The physical speakers are designed to sit comfortably within their environment. They are a beautiful statement, but one where perfectly balanced design neutrality means they will blend in for a lifetime of use.

Every Monitor Audio product is the result of intense collaboration, drawing on decades of experience within the design team and ensuring that all the elements of performance, technology and design work in harmony.

Hyphn is the physical manifestation of this.

Creating A Speaker Nobody Thought Possible

The designers were clear they didn’t want to produce a big box with lots of circles on the front. Indeed, their main challenge to themselves was how to create a loudspeaker that didn’t look like one.

They also recognized, rightly, that you can’t set out to create an ‘iconic’ design, any more than you can sit down to write a ‘bestselling‘ novel; it’s for the market and the audience to judge and grant that status. But they did want the design to be very ownable and distinctively ‘theirs’. And they realized early on that in Hyphn, they had something very special indeed.

Achieved Through Total Collaboration

There’s an element of risk in any innovation. With Hyphn, there was no specific background research and no prototyping – because, with the launch date already fixed, there simply wasn’t time. But the team applied good, solid science and engineering, so any risks were carefully calculated. And when the science is right and the engineering is sound, you can do it like that, because you know, fundamentally, it will work.

The project was possible only through total collaboration and absolute trust between the design and engineering teams; something companies often lose out on by outsourcing their industrial design. Crucially, the team had the blessing of the business to develop Hyphn free of budgetary and other constraints – one of the huge advantages of being an independent business able to control its own destiny.

The Shape Of Genius

Hyphn’s striking outline is a product of the configuration of the drive units; looks are secondary to the technology. Indeed, the concept began with the drive units floating in (virtual) space in the optimum positions; the design team then created the cabinet’s physical form around them. And while nothing was done for the sake of decoration, the design consciously focuses on the M-Array, to draw attention to the most important part of the product.

All loudspeakers are essentially architectural – they’re called ‘towers’ after all – but the description is especially apt for Hyphn. In architecture, a ‘hyphen’ is a link between two separate structures; and in Hyphn, the bridge containing the M-Array provides the only physical connection between the two pillars housing the bass drivers. The design team deliberately avoided anchoring them at the bottom, as logic might have dictated, so as to stop the shape becoming singular.

Engineering The Impossible

Some of the team’s biggest challenges lay in engineering solutions to problems that simply don’t exist in a simple box design. For example, where do you run the cables for the two sets of bass drivers so they can’t be seen? (Through the middle of the drive unit anchors).

Here, as they had throughout the project, they relied on sound engineering principles, which hold that it’s better to make something simple with known issues and fix them, rather than make something highly technical or entirely new. For example, instead of trying to create a ‘perfect’ rear chamber for the M-Array, they simply made it as small as they practically could, then used foam and other conventional techniques to eliminate any resonances. And as it turns out, the bridge actually enables better acoustics and far exceeds the original expectations on what the engineers thought possible.

A Definitive & Uncompromising Performance

Acoustically, Hyphn is almost identical to the Concept 50, which was always intended for production. However, beneath the surface, almost everything was reimagined for even better performance.

The six mid-range drivers in the M-Array appear acoustically as a single source. This creates a very detailed sound field, with stereo audio delivered to the best possible capability, with huge depth of sound. The six small, flat surfaces also eliminate intermodulation distortion from the MPD III Transducer, which research shows is more important than harmonic distortion. This is a much better engineering solution than the conventional single coaxial cone, but simply not feasible in a smaller, cheaper loudspeaker.

Hyphn is engineered to be tonally transparent across the full range from 18Hz up to 60kHz. Importantly, it’s designed to maintain this performance as it’s turned up; it should never sound strained or stressed at any reasonable level in a room.

Perfecting The Art

Hyphn’s unique cabinet is constructed using the highest quality solid surface material available. After lengthy research and testing, Monitor Audio settled on a composite that combines acrylic, minerals, and natural pigments. This creates a smooth, thermoformable, and visually seamless surface, which is then precision milled to produce Hyphn’s striking and distinctive profile.

The acrylic stone material provides the perfect platform from which the drive units can operate to their full amazing potential. It is both totally rigid and naturally inert, so it doesn’t create any unwanted vibrations within the bass cabinet enclosure.

One of Monitor Audio's key brand values and differentiators is that Hyphn is designed, engineered, and hand-built in England. This is important for two reasons.

Firstly, customers worldwide still seek out and respect products that are genuinely ‘Made in Britain’, particularly at the upper end of the market. By emphasizing this fact, they’re aligning Hyphn with Savile Row, automotive brands including McLaren, Rolls-Royce, Aston Martin and Morgan, Barbour, Fortnum & Mason, and other names that help to elevate their own brand.

And secondly, they’re nurturing and supporting high-level craft skills, knowledge, and experience within their own business – something many companies choose to outsource, or dispense with altogether by employing simpler materials and construction methods and/or automation.

Point Source Driver Array

Hyphn’s point-source driver array is located squarely between the twin pillars, each of which houses a pair of powerful 8-inch (203mm) bass drivers.

The unique M-Array configuration features a single Micro Pleated Diaphragm III (MPD III) Transducer surrounded by no fewer than six, 2-inch Rigid Diaphragm Technology III (RDT III) dedicated midrange drivers to deliver sensational acoustic transparency alongside improved off-axis performance.

Hyphn’s unique point-source driver array configuration delivers exceptional soundstage clarity, allowing the listener to precisely pin-point individual instruments and vocals for a thrilling acoustic experience.

The M-Array

The M-Array is an ultra-compact multi-driver midrange and tweeter assembly. A masterpiece of intricate detail and design, the M-Array is a testament to the collaborative approach of acoustic and mechanical engineering within Monitor Audio’s Research and Development team.

Using their renowned RDT III cone technology, the six midrange drivers together have a surface area that is slightly larger than their Platinum midrange driver. An approach that gives rise to multiple benefits.

Firstly, each midrange has an exceptionally wide bandwidth and can cover much of the range of a traditional tweeter. This ensures the smoothest crossover to the tweeter and exceptionally low distortion.

And secondly, traditional dual concentric drivers suffer from intermodulation distortion due to the displacement of the midrange diaphragm, which forms the tweeter waveguide. This can be reduced by limiting the lowest frequency the midrange operates to but never totally removes it. As Monitor Audio’s tweeter waveguide is fixed and the drivers create a flat baffle around the tweeter, there is no additional intermodulation distortion contributed and the midrange can run to its full potential without compromise.

MPD III Transducer

At the heart of the M-Array, sat precisely at the acoustic center of the six 2-inch midrange drivers, is the Micro Pleated Diaphragm III (MPD III) high-frequency transducer.

Developed by Monitor Audio’s acoustic engineers, this accurate transducer was unveiled for Monitor Audio’s 50th Anniversary celebrations. It delivers remarkable performance:

  • The Micro Pleated Diaphragm III (MPD III) extends tweeter passband to >60 kHz (compared to >40 kHz for a typical AMT)
  • Its square radiating area ensures equal directivity in horizontal and vertical planes, resulting in an improved soundstage
  • The rear volume is optimized to ensure minimal ripple in audible frequency range, with gentle rise on-axis to deliver exceptional detail
  • It features an improved waveguide to give controlled directivity and radiation impedance matching, further improving soundstage and maximizing sensitivity

The MPD III Transducer delivers a larger, clearer, and more consistent sound. Music and film are delivered with precision and clarity, allowing the listener to enjoy levels of accuracy and detail beyond what they have experienced before.

Midrange Drivers

Rigid Diaphragm Technology III (RDT III) is a composite ‘sandwich’ structure made from ultra-thin low-mass skins, bonded to a honeycomb Nomex® core material. Extremely light and strong, it can respond with great speed without bending – just like a perfect piston.

RDT III uses Ceramic-Coated Aluminum Magnesium (C-CAM) for the front skin, while the rear skin is made from a woven carbon fiber material. The combination of such a light and strong material structure reduces distortion by over 8 dB above 300 Hz, which makes RDT III the lowest distortion cone technology in Monitor Audio’s history.

Why six, 2-inch midrange drivers? Performance first and foremost – it was about achieving the largest amount of surface area (to reduce distortion, projecting vocals effortlessly) with the smallest footprint - the smaller the radiating area of the drive unit, the wider the directivity for the best in-room integration.

Powerful, Force-Cancelling Bass Drivers

The sheer scale and authority of Hyphn is delivered via no fewer than eight, powerful 8-inch bass drivers – four precisely positioned, and rigidly secured within each Hyphn cabinet.

Each of the four pairs of bass drivers are positioned facing inwards towards each other. They are secured in place by inch-thick metal rods and through-bolt fixings that run through the width of the cabinet to the rear of each bass driver. This fixes the four drive units securely.

The concept of force-canceled drivers is simple: the same force applied to the cone of both bass drivers means the same force will be applied in the opposite direction – an equal and opposite force.

Face two bass drivers in pairs and the reaction force of one will be the same as the other – equal and opposite. This means there is little or no vibration force from the drivers, either within themselves or passed through into the cabinets.

The result is a cabinet that is almost vibration free, with all the listener hearing is the sound; pure, clean, and detailed.


Hyphn has been engineered to deliver enhanced bass control, response, and dynamics, plus exceptional detail through the treble and upper midrange. Crossovers are specifically designed to ensure precise, controlled performance across the full frequency spectrum.

As with everything on Hyphn, the smallest details have been considered, even down to baking the inductors in varnish, which binds the wires together to reduce vibration or mechanical resonance. Ceramic wire-wound resistors reduce power compression, and have also been doubled or quadrupled up where necessary to achieve the desired max power handling (800W).

Bass, mid, and high-frequency sections utilize individual PCBs, which minimizes crosstalk and magnetic fields. Boards have been carefully optimized to minimize the interaction between adjacent inductors and mounted on rubber isolation feet within the cabinets, preventing vibration traveling through the PCBs and components, improving sound quality.

Hyphn is the most powerful loudspeaker Monitor Audio has ever produced.


Hyphn’s unique cabinet is constructed of thermoformed mineral and acrylic stone. The cabinet is then precision milled. The result: a totally rigid structure that provides the perfect platform from which the drive units can operate.

This naturally inert material is perfect for the Hyphn enclosures. With built-in formed strengthening ribs and bracing, with internal and external wall thickness of 12mm up to 24mm around the force-canceling bass drivers, the result is a cabinet that is almost vibration free.

Weighing in at over 106kg each (fully built), the smooth lines and strong visual architectural aesthetic that the cabinets exude will ensure they remain relevant for a lifetime and that the iconic reputation that started with Concept 50 lives on.

Beautifully Finished

Hyphn is expressed in three contemporary finishes, Matte Heritage Green, Matte Black, and Pure Satin White. Each showcases the elegant architectural lines of the Hyphn design. Carefully selected to present a feeling of luxury, each finish deepens the connection and luster of the physical shape, and ensures that Hyphn sits within its environment seamlessly.

Whether as more of a statement center-piece of sonic power or a subtle sculptural design disappearing beneath musical notes, Hyphn represents a physical presence and undeniable quality that will last a lifetime.
