Welcome to MonoPulse Hi-Fi Loudspeakers

With unique impulse synchronism of the drive-units.

The result?

Dramatic, near holographic, realism and sound-staging.

This precision, and its sound, are unique to the MonoPulse design.

Vital integrated bass is also there, deep (Model A sub 20Hz), and powerful (550W), for ultimate hi-fi.

A distinctive style features gloss or satin rolled-steel, over a cloth covering - both in many colours.

All loudspeakers are craftsman UK made, to each customer’s order.

MonoPulse is perfectionist.

Perhaps why over half of our customers are involved with music - and most of the rest are engineers.

We also supply surround-sound and home cinema loudspeaker systems. The front units can be Models A, S or C, and the centre and wall units are based on the Model C.
Any colour combinations are possible.
We have just supplied a seven speaker cinema system to a Mr D T of Northumberland, via our dealer Audio Elevation. His reaction was, "The clarity of sound is astounding. The transformation of our home cinema system has been seismic. Real depth and detail to both music and film soundtrack."

The colours.

There is a choice of ten cloth colours and seven steel colours – including our new brushed bare-steel finish. The colours can match other equipment or blend with the room furnishing. We can send sample swatches to help with your choice.

The cloth colours.

Black

Black — An intense black with a slight sparkle. Matching Black cloth with Metallic Black or Gunmetal steels is popular.

Cranberry

Cranberry — For speakers with a difference. For a small charge we can do the steels in White if you pick this one.

Slate Grey

Slate Grey — A popular colour, combined with Metallic Black or Gunmetal steel, looks great with other equipment.

Bright Lavender

Electric Blue — A dramatic choice, which can go with contemporary furnishing, for loudspeakers with a difference.

French Blue

French Blue — Cool and modern with Gunmetal steels. Great if there is blue-hue furnishing or equipment around.

Champagne

Champagne — Combined with Sand steels, even a performance large speaker can blend with light-coloured furnishing

Burgundy

Burgundy — A vibrant and rich colour which is a good match with Black, Bronze, or Gunmetal steels in a room with red hues.

Bottle Green

Bottle Green — Combined with Bronze steels, belongs in a stately home and doesn't even look like a loudspeaker.

Biscuit

Biscuit — Blends in well with traditional furnishing. A popular choice to go with Sand or Bronze steels.

Dark Chocolate

Dark Chocolate — A rich dark brown which looks particularly good with Metallic Bronze steel or Metallic Black steel.

On surround-sound loudspeaker sets, any combination of colours can be chosen. Some outline of the speaker drive-units will be visible through the lighter colours, the most so with Champagne.

 

For the steel tops - six metallic colours, and a bare-steel finish, all in gloss or satin.

Metallic, Bright Silver, Gunmetal or Black.

These metallic colours can match other hi-fi equipment. They blend well with Slate or Black cloths.

Metallic, Bronze, Sand or Burgundy.

These can match room or furniture colours. They blend with our Dark Chocolate, Biscuit or Champagne cloths.
The Metallic Burgundy can be a dramatic contrast, or blend with the Burgundy cloth.

The new Brushed Bare-Metal finish - shown above right with Champagne cloth.

A brushed lacquered finish which shows the solid reality of the quarter-inch thick rolled-steel tops - and reveals the varying patina of the rolling-mill.
The first customer to receive one, in Spain, immediately e-mailed "They are lekker, you have done a fine job at interpreting what I was looking for visually."

 

MonoPulse export versions.

Certain higher specification components are used for humidity tolerance, power surge resistance, insect exclusion, and superior impact tolerance.

 

Reviews.

MonoPulse hi-fi loudspeakers have been listened to by the UK's most respected reviewers.

There are over thirty-five published reviews of the Models A and S.

What continually sets us apart, is the praise for realism - the objective of the original quest.

To see some quotes click here or the full list and texts click reviews

Recently we have been too busy to submit any speakers for review. So the Model C (shown right in Slate cloth and Metallic Black steel) which is all new, has not yet had trade reviews.

But a Norwegan customer posted this very comprehensive revew of every aspect of his Model C. Follow this link to an English translation in PDF format Norway PDF It may take some seconds to download.

 

General features, and options available on all our hi-fi loudspeakers.

Terminal panels are bi-wireable, or bi-ampable, and can accept 7mm spade connectors, 4mm plugs, or 5mm wire. They have all-soldered internal connections.

Crossover components are to the highest specifications, using heavy-duty air-spaced inductors and film capacitors.

External surfaces can be re sprayed or re covered for repair or colour change.

Colours. In addition to the ten standard colours, we can sometimes obtain other colours to special order.

Specials. Because we only make to order, we can often supply special requirements. For example, shown above, is a connection panel from a source specified by the customer, fitted at the very base of the speaker enclosure.
We can also make acoustic specials with modified bass or treble, including adjustable treble.

Spikes can also be supplied in hard nylon, more suited to hardwood floors, as a no-cost option, as can extra long spikes to give stability and clearance on deep carpets.

We have so many favourable comments from Norway that it would be impossible to add them to the site. This is the latest, dated November 2011, comment from Ian Christiansen, who ordered a pair of Model S speakers.

Hi Allan,

I would just like to thank you for both excellent speakers and outstanding service. It has been a pleasure buying speakers from you.
I have now tuned the placement of the speakers a little and they now play sub bass and middle bass like champions. I am very pleased with all sides of the sound from the speakers.
Micro dynamics are excellent, speed and timing is fantastic and they have excellent midrange on voices. And now the bass is outstanding too. A very complete speaker in my opinion. A perfect speaker for me that likes the speed and timing so much. I am very pleased with the result and it is so much fun that I have started to play old records we have not listened to in years.
The speakers have already surprised me many times on records I thought could be difficult, but they have played everything extremely well and with authority that modest sized speakers normally should not possess. So this renewed interest for listening is very good and we often play some records after the kids are in bed in stead of the usual zapping the channels of the TV all evening. I have put some pictures and a short review on the MonoPulse friends thread on hifisentralen.no so I hope my positive review will contribute to give you some more Norwegian customers.

Best regards, Ian

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 hi-tech thriller he would have wanted on one of those flights. Click on End Game to find out more about that.

It can be obtained from Amazon on Kindle, or Book, and Waterstones. (In shops quote ISBN 9781848972438.)

Some of those reviews

The Model A speaker at its second Best Buy award from the prestigious Hi-Fi Choice.

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.

What Hi-Fi"Extraordinary powers of timing and resolution;.. In terms of timing alone the Ss are 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 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." Five stars

 

The Model A speaker immediately received a Best Buy award from the prestigious Hi-Fi Choice.

Hi-Fi Choice"The first thing one notices is just how coherent and 'real' it sounds."

"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."

 

Hi-Fi +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

Hi-Fi news"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.

What Hi-Fi"latch on to the leading edge of every note with breathtaking confidence."

"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 –Five stars

 

Paul Messenger, probably the UK's foremost loudspeaker reviewer, about the Model S.

Hi-Fi Choice"Delivers a coherence and timing that's positively electrifying. It's a vivid edge-of-seat experience, which somehow seems to 'direct-couple' the music to the brain. Playing Christy Moore's Live At The Point, it was almost as though one had been transported to that famous Dublin venue. The exceptional image precision - a sure sign that this speaker does indeed have phase accuracy that's very rare indeed in a regular box speaker. No less interesting is the styling here, which is very original and also decidedly attractive. A vivid sound that gets you close to the music. Something very special in the way the leading edges of voices and instruments are defined. The shock of the real. Sheer excitement."

Keith Howard, consultant Technical Editor for the prestigious Hi-Fi News, about the Model S.

Hi-Fi news"Its fundamental honesty of sound is its key attribute and opens a window on a musical performance in a way that slugged-sounding speakers - of which there are still too many - never can. This is what real high fidelity is all about."

David Alcock, specialist top-end stereo speaker reviewer, about the Model A.

Hi-Fi news"Fancy electrostatic sound from a sharp looking conventional speaker? Meet the MonoPulse Model A. It brings the kind of resolving capability and imaging one would normally associate with electrostatics like the Martin Logan to a far wider audience.

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."
