MonoPulse Hi-Fi Loudspeakers give fantastic realism by their time-domain impulse accuracy. Using a genuinely new and different approach, these British high-fidelity loudspeakers excel in creating an accurate acoustic image and sound stage. They are hi-fi speakers to re create the live performance right in front of you - and custom made to each order, in a wide range of colours.
The A Models, 42A, 72A and 82A. No compromise. Form follows function.
Just one look at the unique and expensive construction of the MonoPulse A Models, reveals our dedication to a primary design objective - absolute precision of impulse and time alignment. This is a perfectionist concept, with the HF drive units separately suspended under wide, quarter-inch-thick, rolled-steel surrounds. The impulse alignment we achieve by this isolated and offset mounting, is one of the keys to MonoPulse realism. For a technical explanation click.
These speakers are our original audiophile design, for users who don't want any compromise. They have three times been a Hi-Fi Choice Best Buy.
And this approach, of craftsman individual build, also enables us to offer a unique range of fifty colour-combinations.
A Models feature a very easy amplifier drive of 9 ohms nominal, 7 ohms minimum.
The dimensions are 108cm high and 23cm wide.
Shown right, in Dark Chocolate cloth and Metallic Bronze steel.
This is the lowest cost version of the A Model concept. Power handling is 100 watts continuous, 200 watts maximum.
The Model 42A has deep but tightly controlled 25Hz bass from the 200mm, polypropylene-coned LF drivers in generous enclosure volumes.
At the high-frequency end, there is amazing 30kHz treble from 28mm diameter, ferrofluid-cooled HF speaker units.
So, for Hi-Hi News, "High frequencies were richly detailed, ensuring that instruments buried way down in the mix are clearly discernable as individual".
For Hi-Fi + it was "the sheer speed and integrity of its music making."
For Hi-Fi World they give "a fabulously integrated big and relaxed sound ..."
For What Hi-Fi "- these speakers grip and control information like the Stasi,"
Shown right is the rolled-steel loop which separately suspends and isolates the HF units. You can also see the acoustic break below this, preventing intermodulation between the drive units.

The Model 42A has been selected by the prestigious new dealership True Stereo in Kensington and Chelsea, to feature in their £9,995 Reference System - see their site www.true-stereo.com
A brief comment about the review of the Model 42A in the July issue of What Hi-Fi. We had very high praise for the acoustics, "amongst the most focused and effective loudspeakers at any price". But they were critical of the finish, repeating the comments in their December review - which we took seriously and made changes to all models, including a metallic high-gloss finish on the top steels. Unfortunately the latest test speakers were needed at short notice and the only pair available were to the old standard. We have a provisional agreement that What Hi-Fi will review the Model 82A, finished to the latest standard. In saying this we do not presume what their reaction will be to our changes.
The amazing top-of-the-range Model 82A will handle 300 watts continuous, 550 watts maximum, and 1,500 watts for 10ms.
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 a fabulous top-end of 30kHz.
There is no other hi-fi loudspeaker which will deliver timing purity of all the frequency components in musical leading edges and impulses, and with this frequency range and power. Simply none, at any price. For the technical background to this statement click
The Model 82A also won Hi-Fi Choice Best Buy. "The first thing one notices when placing and connecting up the 82A, is just how coherent and ‘real’ it sounds. Timing is truly exceptional."

An intermediate with some extras.
For export markets, the Model 72A has power handling of 150 watts continuous, 300 watts maximum, 24Hz bass, and 30kHz HF units.
Certain higher specification components are also used for high-humidity tolerance, power surge resistance, insect exclusion, and superior impact tolerance. It is otherwise as the Model 82A.

The S Models, 32S and 62S. Slim and elegant performance.
More conventional looking, but still far from being wooden boxes, these are custom made, perfectionist designs, at the price of volume stock speakers.
MonoPulse impulse and time alignment is maintained, delivering fantastic realism, presence and sound staging, even in this smaller package. For a technical explanation click
The HF speaker units are 28mm, aluminium-wound and silk-domed, with Neodymium magnets.
LF drivers in generous enclosure volumes give big bass. Our newest model, the 62S, has 200 watt power-handling from 160mm LF main drivers with 54mm diameter Hexatech aluminium voice-coils.
These drive-units, with their precision spacing and special crossovers, deliver musical leading edges with every frequency component in full impulse synchronism - the key to realism.
The S Models are 92cm high and 17.5cm wide.

What Hi-Fi immediately gave the 32S 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." Look at all the Model 32S reviews

The Model 42A 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 32S loudspeaker was immediately given the top five star rating by What Hi-Fi.
"The 32S's vibrancy, accuracy and and rhythmic presence is extraordinary enough to warrant five stars on its own. The 32Ss 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 82A 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 42A 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 new 32S 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 32 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 42A ...
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."
