Two weeks ago I had the possibility to hear the Isobariks
for the first time. Powered by 6 x CB135s, NAXO, 52 and CDS.
Best musical
experience ever, a dream !
Customer testimonial :
Hi Simon
Although I haven’t spent as much time as I would have liked
listening over the weekend, I have spent enough to get a feel for what you have
achieved with the modification work.
I am quite amazed by the transformation in the overall sense
of realism and depth of field. As I said to you the other day, there aren’t many
live albums that can be faithfully reproduced at home and give you the sense of
‘being there’. But the ‘Bruce Hornsby and the Noise Makers’ album is a fantastic
piece of work and deserves playing on equipment that can do it justice. I think
my system does that, thanks in no small way to the improved
Isobariks.
I have worked through one or two of my usual test CDs… music
I really enjoy, recorded with the attention to detail that lets them breath
properly when played. If these discs work then the system works,
essentially.
I can only say that I am closer to the level I want to reach
than at any time in my Hi-fi journey. I’ve had some pretty decent kit over the
years… Krell amps, Martin Logan ‘speakers, Copland CD players, Nottingham
Analogue record deck… so I am familiar with what works for me and what
doesn’t.
The current set up is very close to complete now. I think the
power supply improvements we talked about with Shaun, the balanced cables and a
third KSA will make things better without detracting from what is there already.
One step at a time though, I think.
In conclusion, I would say to anyone who has a pair of old
(and perhaps tired) Isobariks that would love to breathe new life into them…
check out Simon Hamnett’s work.
From where I sit (and listen) he knows how to take the
‘speaker on to new levels without taking away the essence of what the original
Isobarik does. The work done on my pair has transformed my listening experience
to the point where I believe and enjoy what I’m hearing again, instead of
wishing that certain elements of the performance were better.
I’m not easily pleased (or impressed) by Hi-fi but I am
incredibly happy with what has come out this exercise.
To all those skeptical people who like to speculate on how
good or appropriate or effective Simon’s work is, largely without listening I
might add, I would say you need to accept that the world of Hi-fi has moved on
and taken the Isobariks with it thankfully.
Thanks for an excellent job, Simon
With Best
Regards

Four myths busted !
- Myth one : Linn Isobariks sound
coloured. Or more precisely suffer from colouration. ( Over emphasis of certain
frequencies )
Yes they do !
Standard late model passive Isobariks even when
driven properly; and,.. you do need some very serious amplification to drive Briks
properly, do sound very warm, smooth, and easy on the ear. This is due in part ( Ivor was trying to hide Sondek inadequacies ! )
to the standard five different types of passive crossover network, and the
standard tweeters. But mostly this is because of the very poor quality of the
Kef B110 Mid range driver. I can hear owners of that other little speaker with
big reputation; the LS3 5A - gasping with horror. I apologise, but it is
a simple fact that the B110 is not the best mid
driver in the world ( certainly not anymore it’s not, and not 40 years ago
either ! ) and when upgraded in the Linn Isobarik cylindrical midrange enclosure
( similar the JR 149 ), huge improvements can made over the standard Kef B110. Time
and again customers phone me to say how pleased they are with this modification.
The B110 is long dead (has been since about 1979 actually) - It really is time to get over it chaps -
sorry. And yes ! - The original designers at Falcon have re manufactured a very excellent brand new B110 now, and yes, it does sound very nice. But in reality the warm coloured characteristic sound of the New/Old B110 is exactly that - a Characteristic sound. Not an OPEN and accurate rendition of the original sound - This is what the Kevlar/Carbon upgrade offers you. Try it and hear for yourself in your own home. I'm very happy to supply the new Falcon B110 should you require. Falcons new B110 is THE BEST B110 your money can buy. However, our ears tell us there are stunning improvements to me made, should you, dear client, desire this to be!
The excellent upgrade we favour is the
Monaocor Kevlar cone mid range driver with phase plug or 'Plain Carbon fibre Black'. This major ‘night and
day’ ( as one client called it ) upgrade requires cabinet modification, and for a completely
professional factory fresh perfect look, these units are fitted by our cabinet
craftsman. Other B110 footprint units are available so please inquire so that we
can find just the right mid unit for your needs and budget. Carbon fiber cone drivers in black are also available for the more traditional B110 look. You chose. Ultimate Scan speak mid range conversion also available. Please just ask for full details.
Like wise the standard tweeter drive
units from Scanspeak and Hiquphon can be upgraded with outstanding results. Our favorites are from the Scanspeak Revalator range. The vastly improved the “top
end” you require is finally here for you to - 'hear' for yourself. This
modification may or may not require modification of the Crossover
Network. Again the choice is yours ! This is of course is far easier to do when your Briks are
driven actively as they should be - it's not that expensive. The sweetness of treble from a one inch soft dome Scanspeak has
to heard to be believed. No
one has as yet requested they go back to their old tweeters. Which are also available should you need them of course.
- Myth two
: Isobariks
provide very poor stereo imaging. The driver arrangement is poor.
This
statement comes up again and again on the forums. It makes us really quite
angry. It is simply just not true, Briks can, when set up and
driven correctly, in full active mode, with the right crossover
and CORRECT cross over power supply, provide quite stunning holographic
imagery. Better than ALL other speakers I’ve ever listened too. If I’d heard
better speaker I’d have bought them! Imaging is the active Linn Isobarik strong
point. The fact is people have never really heard a properly set up
pair of Briks. They are a rare and exotic beast of a speaker, and up until
recently very expensive ! – But now as second hand prices fall, it is possible
to build a full active Brik system for a fraction of cost of what it would have
been the old days.
- Myth three
: Isobariks have a very strong articulate
bass response.
This myth is very true ! Quite frankly
– It’s the best bass you’ll ever hear ! However upgrading the Kef B139
isobarically loaded drive units yields even better results. Unfortunately the
“race track” B139 footprint versions by other other manufactures are very
difficult to source. We favour the Elac unit used in the past by IMF/TDL, but as I
say, these are difficult to obtain second hand. The next best is the Keltic bass
unit available from Linn. These are expensive, but are an improvement in terms
of attack and slam over the standard B139 units due to the Keltik bass units
lightweight cones and extra sensitivity. If anyone knows of better bass than
Isobarik bass PLEASE TELL ME ! And please
keep all your transmission lines, no matter how big. Clearly you've not heard
properly set up Isobarik four pack bass. Infra bass like you've never listened
to before. We are talking seriously powerful, articulate, precise, perfect bass
- like you have only dreamed of in the past. Not convinced ? Try them for free in your own home.
If you have better bass I'll buy your speakers and you'll owe me nothing.
- Myth four
: Wives, girlfriends and partners hate them.
Our wives love them, listen to
them all the time, either whilst feeding the baby or just in the evening and
weekends after a hard days work for some very serious relaxation. They can be
tastefully integrated into most rooms, and room size is irrelevant. We have
installed Briks in a room ten feet by ten feet square, and that system could
literally blow the listener away ! The key, as I hope you have gathered is
correct setup.

Many eBay adverts speak of an items rarity.
I have been working with and dealing in Linn Isobariks since before 1990. In nearly 30 years I've only ever seen four Naim Naxo 3/6s for Isobariks actually in the flesh. That means I can
get my hands on a NAXO 3/6 in about once every seven and half years.
This is your lucky chance to grab a genuine Chrome Bumper Naxo.
I've never seen one as clean as this, it's beautiful, no question..
If you can find another immaculate comparable beautiful condition fully boxed Chrome Bumper Genuine NAIM NAXO complete.
Available anywhere on this planet
LET ME KNOW !
I'd have be very happy to keep this one for my collection !
But I had the right offer and the new lucky owner became the next custodian of this iconic
piece of genuine Naim inspiration. I can't keep it all !
It will be an appreciating investment.
Don't believe me ?
- You only have to look at whats happened to boxed original mint condition Naim gear prices in the last 10 years.
They only ever go up.
A note regarding Naim Chrome bumper gear.
In
my opinion CB gear with it's classic retro appeal is by far the most
attractive gear Naim constructed. It's exceptionally well made, quiet
stunning. Of course the era was over seen by late great Julian Vereker
himself. The original and the best. Couple this with a six pack of CB
135s 0r Three CB 250s and you'll be in audio Nirvana.
Guaranteed or your money back.
Don't be fooled into believing the olive or later gear is better.
It's not ! Chrome gear is becoming even more sought after.
Happy to demonstrate this to anyone who would like to listen.
Chrome Bumper era equipment represents the best Naim Ever made during their hey day under Julian.
Now under French firm 'Focal' I feel... well - Look and listen for yourself.
How does a Naxo sound compared to the later Olive Snaxo ?
Good question, there is absolutely no doubt that many Brik owner favour the sweetness of the NAXO over the SNAXO.
Some owners go back to the Naxo from the Snaxo
Not convinced ? Please feel free and by all means check out the forums for yourself to see if I'm right ??
I offer a buy back scheme on all equipment I work with.
You've nothing to lose.
EXAMPLE PICTURE ONLY - SYSTEM NOT INCLUDED.

Ok, any questions please just ask -
Many thanks for your interest.
The Isobarik loudspeaker was originally available in two
types: DMS (domestic monitor speaker)
and PMS (Professional Monitor Speaker). The main difference
between the two was the
crossover: DMS were fitted with an internal passive crossover,
whereas PMS had no crossover
at all, and instead used an external Active crossover.
DMS were discontinued in 1988 due to the introduction of an
external passive crossover. This
improved passive performance and allowed very easy upgrade to
Active.
Each speaker has two of each drive unit fitted – i.e. two
bass, two mid and two treble. The
second bass unit is hidden inside the cabinet, behind the
visible bass unit and this forms the
basis for our patented Isobarik equal-pressure bass system.
This means that the front speaker
behaves as if it is in a much bigger enclosure.
