Extreme Story
It all began at a Jan Garbarek concert: an electrifying show,
recorded for their live album.
The audio quality was superlative, I listened to it as if in a
trance. Then a challenging question struck me halfway
through the concert: “why not try developing an unprece-
dented high-end speaker system?”
I was ready to do battle to get this challenge onto the
drawing board and so the next day I immediately men-
tioned it to Emilio, chief of Macrom’s Research &
Development department. Embarrassed like a kid
caught red-handed, Emilio confided that he and his
team had secretly been working on the idea for
some time.
I felt very excited. But how can one concentrate on
such a highly creative project while sitting in the
office dealing with the thousands of everyday
tasks?
Thirty minutes later, Emilio and I – with notebook, pen, heaps of ideas
and no mobiles – drove up into the Swiss hills. Destination: a restaurant famous for
its cuisine, hard to get into during the weekend but quiet on the other days.
By 3 p.m. when the waiters had begun hinting that although hospitality is sacred, it also has its time
limits, the first sketch of what were to be the Extremes was down on paper.
After that day, we spent whole weeks talking during the day and thinking at night. But
our project was having trouble getting past the embryonic state – we were at a stand­still.
And then a stroke of genius suddenly hit us during one of our by-then-habitual brainstorming sessions at the restaurant. “Fred, what’s the best tweeter?” Emilio asked me point-blank. “Our 57.16S” - I replied
- “because it has unbelievable frequency response and acoustic performance.” Emilio was of the same mind and stressed that its resonance volume and other innovative solutions made it virtually unique. However, I reminded him that the 57.16S was difficult to install due to its large size.
After a brief silence, Emilio whispered as if to himself: “OK then, that means we’ll have to make a 57.16S with a neodymium magnet to keep it small, and with a removable resonance chamber!” I could have hugged him: that’s how the idea of the Extreme tweeter was born.
The woofer was also conceived during
a lunch break. Emilio drew it on a paper napkin and I can testify that it
was very similar to the final model
you find today.
Insert the face plate into the hole from the front and fix it
in an audio system. NEVER connect it without the correct capacitor/condenser/filter when instal- ling these units as part of the system.

The guidelines for the Extreme System were now set out: the speaker had to have a basket relatively open at the rear to obtain a more brilliant, color-free sound, and had to be built in the usual sizes: 165, 130 and 100 mm.
As concerns the 165 mm model, I insisted it be optimized to produce good bass tones even if installed in the door and Emilio straightaway said: “I agree, Fred. And that’s why I’m looking to develop a truly special speaker. I’ve got a revolutionary idea in my head…”. And so he explained his ideas to me: it would be possible to concentrate the best dynamic and timbre performance of the entire system in a single speaker (two 165 mm midwoofers and a 100 mm midrange in each door) by judiciously optimi­zing the Thiele and Small parameters, making the performance extreme only in that part of the frequen­cies involved, and by using a special cone.
You think that’s easy? Just to come up with the right cone, we and the R&D team deve-
loped almost 100 speaker prototypes in 165, 130 and 100 mm sizes, combined with numerous magnetic circuits and various voice coils. We rejected the idea of testing by
computer right from the start – music computers don’t understand a thing! – and deci-
ded to rely strictly on our own sensations. At the end of the day, we chose the magnesium cone and a 32 mm voice coil. Why? The answer is easy: because magnesium is an excellent material and the performance is out of this world. After a few more nights of tests and counter-tests, we were ready to try out the first prototype in a car.
It was such a rainy day that it seemed as if the sky was dropping on our heads. I won’t hide the fact that the weather only inspired us with the grimmest pessimism. We hooked up the speakers to a Synthesis amplifier and began with a number by James Newton Howard. Emilio and I got goose bumps: the sound was simply exceptional, with the sound-scenario sculpted so well in front of us that we felt we were at the concert with James. It was a hugely realistic live concert experience, exceeding all our rosiest expectations.
Only the crossover was missing. When I suggested using the specially built passive filter that I had used for the IASCA competitions,
Emilio laughed right in my face, saying that that crossover – as big as a car – was simply
ridiculous, although he did admit it put out an excellent sound.
And so, we selected the best components (polypropylene capacitors, air-wrapped
inductors, etc.) and developed a truly special crossover, so special and spectacular that
we enclosed it in a Plexiglas housing.
It took us 18 months of hard work to develop the Extremes. And then we camped out for hours and hours in the Macrom demo room to compare the music of our Extremes with that reproduced by the competitors’ speakers. But that’s another story.

Installation
The Extreme speakers use the Magnesium cone technology: they are very delicate to the
touch and for this reason we protect the cone with a transparent cover.
If you remove the transparent cover handle the speaker with great care.
Once the cover is removed, Macrom do not accept the speaker cone under warranty.
Take care to keep all dirt, metal cuttings and other debris clear of the speaker during the
installation procedure.
Under no circumstances the cone, with hands,
tools or other things.

These speaker units have been designed spe­cially for use as part of a car audio system. Correctly installed they will provide hours of listening pleasure. Take care to keep all dirt, metal cuttings and other debris clear of the speaker during the installation procedure. NOTE: These unit is made to be used as a
tweeter in an audio system. NEVER connect it without using the correct capacitor/condenser/filter when installing these units as part of the system.
Remove the part where you
need to fit the tweeter and
drill a 59 mm hole in
the requied position.
Insert the Tweeter into the rear chamber and screw it on the triangle face plate. (connect cable through rear chamber access and put again the sponge filter into the rear chamber) Use the supplied screws (3MAx12) to fix the face plate on to the desired position.
The rear chamber is designed to increase the excellent performance of the Ex 32tw.
Coupling the tweeter with a large rear air chamber, reduces the resonance frequency
of the tweeter itself and delete the reflection with the woofer.
Remove the part where you need to fit the tweeter and drill a 59-mm hole in the required position. Insert the Tweeter into the back plate and screw it on the faceplate.
NOTE: Before screwing the face place, you need to adjust the sprung steel behind the back plate. By checking the thickness of the part where you need to fix the tweeter, adjust the space between the faceplate and sprung, using the screw in the middle of the back plate.
