The realism of a pure electrostatic - with the frequecy-range and power of moving-coil drivers.
Eleven years of research has produced a 20Hz to 30kHz audio spectrum, and 550 watts of power handling - but with electrostatic impulse precision.
Their striking appearance, and the massive steel surrounds, are entirely a consequence of the design’s special requirements.
All MonoPulse hi-fi loudspeakers are craftsman-made in the UK to each customer’s order, and are offered in a wide range of colours.
With their combination of realism, sound-stage, frequency-range and power, these are unique high-fidelity loudspeakers.
Over half of our customers to date have been involved with music in some way - and most of the rest seem to be engineers.

What Hi-Fi gave the Model A their top, five star, rating in the Awards 2009 issue. Read more here. Their final words:
"fabulously, uniquely brilliant."
There are three sizes, the Audiophile A, the Slim S - and the Compact C.
These are summarised below:
The Model A - Audiophile. No compromise. Form follows function.
The unique construction of the MonoPulse Model A reveals our dedication to that primary design objective - absolute precision of impulse and time alignment.
A perfectionist concept, then individually craftsman built, this is our original audiophile design, for users who don't want compromise. They have three times been a Hi-Fi Choice Best Buy.
A key to the MonoPulse is the isolated and offset mounting we achieve by separately suspending the HF drive-units under wide, rolled-steel surrounds.
All MonoPulse models also feature amazing 30kHz treble from 28mm diameter, Neodymium magnet, ferrofluid-cooled, HF drive-units.
Unique patented crossover elements, couple the HF to Kevlar LF/MF units which are only 10mm narrower than the enclosure width.
A range of sixty colour-combinations offers matching with anything from the most modern to the traditional.
The Model A dimensions are 108cm high, 23cm wide and 25cm deep, as shown above right in Burgundy cloth and Gunmetal steels.
The Model A has had these reactions:
From Hi-Hi News, "instruments buried way down in the mix are clearly discernable as individual".
Hi-Fi +, "the sheer speed and integrity of its music making."
Hi-Fi World, "a fabulously integrated big and relaxed sound ..."
What Hi-Fi - giving five stars
"these speakers grip and control information like the Stasi"
Shown right is the heavy rolled-steel which separately suspends and isolates the HF units. You can also see the foam acoustic break below this, preventing intermodulation between the drive units.
The Model A will handle 300 watts continuous power, 550 watts maximum, and 1,500 watts for 10ms.
Their ease of drive and efficiency also means they have been operated successfully with 6 watts from a single-ended valve amplifier.
Frequency response is from sub 20Hz, (as measured by Hi-Fi Choice) from Kevlar-coned 200mm drive units with 40oz magnets and 4 layer voice coils. The HF response then goes up to that fabulous top-end of 30kHz.
No other hi-fi loudspeaker delivers timing purity of all the frequency components in musical leading edges over this frequency span, and with this power range. Simply none, at any price. For the technical background to this statement click on The quest for realism
The Model A also won Hi-Fi Choice Best Buy. "The first thing one notices when placing and connecting up the A, is just how coherent and ‘real’ it sounds. Timing is truly exceptional."

Certain higher specification components are used for high-humidity tolerance, power surge resistance, insect exclusion, and superior impact tolerance.
The Model S. Slim and elegant performance.
What Hi-Fi gave the MonoPulse Model S a five star review , saying,
"other loudspeakers sound blurred and hazy by comparison."
92cm high and 17.5cm wide, and more conventional looking, these are still perfectionist designs, and craftsman built to each order.
MonoPulse impulse and time alignment is maintained, delivering fantastic realism and sound-staging. For a technical explanation click on The quest for realism
The Model S features 30kHz HF units, combined with 160mm MF/LF drivers in generous enclosures to give big bass.
They have 300 watt maximum power-handling and embody important features for valve amplifiers and vinyl sources.

What Hi-Fi immediately gave the Model S speakers their top, award.
"Extraordinary powers of timing and resolution; ... timing almost ridiculously good. Music is delivered with a sublime rhythmic precision, a shapely sense of phase and beat that makes other loudspeakers sound blurred and hazy by comparison."

The new Model C. Compact standmounts with surround-sound variants.
Now available from Setember.
These neat new speakers still pack maximum power-handling of 250 watts per unit, and all the MonoPulse impulse accuracy and realism is maintained.
Acoustically optimised for mounting on stands or shelves, they are 49cm high, only 18cm wide, and 20cm deep. Each speaker weighs 7kg.
Also shared with the most expensive MonoPulses are the 30kHz HF units. The 135mm MF/LF units are Kevlar-coned with four-layer voice coils.
They are shown above right in Slate cloth with Metallic Gunmetal steel tops.
The Model C also comes in surround-sound enclosures for both wall and centre mounting, still with 250 watt max power handling.
The Model CW, wall mounting units, are 35cm high, 18cm wide and 20cm deep.
The Model CM, middle unit, is 19cm high, 45cm wide and 20cm deep.

Some background to the creation of MonoPulse.
Having built his first loudspeakers at the age of twelve, MonoPulse designer, Allan Hendry then went on to a degree in Electronic Engineering at King’s College, London.
A career, though mainly in aerospace, also included projects in secure communication systems, cryptography, covert diving systems, cryogenics, and space breathing equipment. He became a board member of a FTSE 100 company, and a Fellow of the Royal Aeronautical Society.
For how all this gave him the idea of the MonoPulse design click here
And in all the travelling, clocking up a million air-miles, he also wrote the thriller he would have wanted on one of those flights. Click on Seeds of Destruction to find out more about that.

Reviews
Because of demand overload rather than policy, we haven't offered many units for review recently, but, in the preceding six years, MonoPulse hi-fi loudspeakers were listened to by the UK's most respected reviewers – and what continually sets us apart, is the praise for realism. And we continue to improve the designs.
See the panel below for some review highlights. Or for a full listing of all thirty-three media comments and reviews click here.
The Model A speaker at its second Best Buy award from the prestigious Hi-Fi Choice.
"remarkably impressive coherence, especially through the voice band, which seems to be MonoPulse's particular stock in trade.
This in turn helps to sharpen the image focus and precision, more accurately and convincingly defining the position of a performer in space." "The large main driver helps deliver fine performance through the bass and midband, with good overall balance and ultimate bass extension."
"Best of all is dynamic expression, which is comfortably ahead of the pack and further enhanced by the superior timing and across-the-band time coherence."
"Superb voice coherence. 25Hz bass extension."
The MonoPulse Model S loudspeaker was given the top five star rating by What Hi-Fi.
"The S's vibrancy, accuracy and and rhythmic presence is extraordinary enough to warrant five stars on its own. The Ss do one thing well - like Jimi Hendrix did one thing well. They do that one thing so staggeringly well that you could spend years enjoying that one talent."
The Model A speaker immediately received a Best Buy award from the prestigious Hi-Fi Choice.
"MonoPulse uses the phrase 'transient synchronism', and that's as good as any to describe the crispness and clarity with which individual instruments are defined."
"Timing is truly exceptional."
"Its music-making is hugely involving and entertaining. And that, after all, is what it's all about."
The MonoPulse Model A received a fantastic review in Issue 42 of Hi-Fi +.
“sheer vividness of their music making … the shock of reality … a fine partner for low powered valve amps … remarkable immediacy of performance ... the sheer speed and integrity."
"Does bring a crispness and a very welcome dose of realism by preserving good leading edge integrity."
"Dynamics somehow seem to sound punchier and more believable. Superb transient integrity with very little to criticise elsewhere in the performance. Makes listening to any source unusually easy and interesting."
"Plenty of deep bass extension. Imaging is impressive, giving notably precise soundstage focus."
"Music sounds beautifully coherent, so that one is rarely conscious of any intrusion of the speakers themselves, while the brain focuses instead on the subtlety of the music making process."
"A genuine audiophile product at a very realistic price.”
Keith Howard, Technical Editor of the prestigious Hi-Fi News, about the Model S speaker
"if you're looking for a speaker to take you directly to the core of the music, few rival this revamped MonoPulse at the price ... its rare ability to cut through to the heart of a musical performance is something that many listeners are certain to treasure."
Hi-fi News independent measurement also conformed a top-end frequency response through to 29.5 kHz.
The first MonoPulse Model S top five star rating by What Hi-Fi.
"They time superbly, and can deliver a complex rhythm track such as Gorillaz's Dirty Harry in as surefooted a manner as any speaker at this price."
"Detail is impressive and dynamics vivid. Great for the money –

David Alcock, specialist top-end stereo speaker reviewer, about the Model A.
The ability of these speakers to capture the subtle nuances and inflections in vocal performances is outstanding. High frequencies were richly detailed, ensuring that instruments buried way down in the mix, are clearly discernable as individual instruments and are never allowed to dissolve into a high frequency hash as is so often heard on lower cost speaker designs. Allan Hendry has identified a key component of delivering realistic sound. Outstanding speed and imaging at the price."Look at all the Model A reviews »
