Post Subject: Aries Cerat Symphonia, version 2020Posted by Romy the Cat on: 1/3/2020
Nine years ago, when I posted the initial post in this
thread the Aries Cerat was a different company with different products.
As I understand in 2014 they changed a lot and today they have a speaker that I
would like to talk a little: Aries Cerat Symphonia. Again, I never heard
it, I do not recommend anybody to buy or not to buy it, I just want to observe
and to comments about the directions where this horn making company went.
Obviously, the marketing write up they presented at their
site is pompous garbage to a great degree, all of the companies do it, and
there is no need to blame them in it. Let try to read between the lines and to
reconstruct what they were trying to do.
The Tweeter. RAAL ribbon. To me it looks like standard with
version. I would like to see in there more narrow ribbon. The reasons why they
went for so wide ribbon is because they ether they did not want to pay for
customization or because they put it on too low crossover point. They fact the
they chose to load the ribbon into horns also saddest that they use low crossover
point. I do not know where they cut the tweeter but I think it will be well
under 10K. Generally I am not a huge fun of this configuration and I would
rather to see a MD is full able to go to 10K.
The MF channels. A 4” titanium cone compression driver. I understandable
not a hug fan of titanium diaphragms. Still I do not know what the driver is.
The multitap transformer before the driver is interesting but in DSET
configuration kind of irrelevant. I would argue the validity of transformer
before the MD driver. Most of the people
who use those speakers would drive them with SET amplification, so it will be
two transformers in sequence? If you in so much need to attenuate the MF channel,
you use a single amp and you do not want to use a voltage divider then why do
not run MF from another tap of your output transformer of your amplifier? I do
not get it. Another thing that I do not get. They use some of the La-horn
profile philosophies and they are very proud that they “eliminated all possible
diffractions”. To a degree it is a valid statement as Le Cléach profile indeed
has less detractions. Still they did not run the proper La-horn curve and they
at the very edge of the horn introduced very harsh border. It might make the
hoe to look sexy but it is absolutely defeating the purpose of killing the
The mid bass. I have written tone about this type of the configurations:
I very much hate yellow driver with back loaded horns. They all sound like sewer
pipes and this one not exception look like. I am
not the person who make a concussion about sound by YouTube video but feel free
to be my quest.
The garbage music they play at this video has one remarkable
quality. Any single note under 100Hs sounds
like the very same generic note. Tis is not the YouTube or your computer garbage
sound, it is how the choked back loaded horns sound.
They claim the they have Bass Horn but it is not on the
picture and the description is very general. My presumption is that they have
no Bass Horn but wiling to build it on demand. The choosing of the tractrix
flare of 3.3 meters is kind of peculiar but I do not think they know what they
are writing as they did not build it yet.
How what I do like in the new Aries Cerat. The time-alignment
and constant group delay filters. Just perfect.
Only this should elevate the Aries Cerat over all competitors. The integration
of the front-fairing yellow driver with horns is very interesting concept. Some
of the yellow drivers properly used and properly drive and with a limited range
can be incredibly interesting as they have transient characteristics like no tomorrow.
I do not know HOW Aries Cerat did it but I find the direction is lucrative. The
MF they mostly like use at 350Hz and the midbass under it. I would like to have
a good yellow driver at let say from 700-800Hz to fairing up along with MF horn
where yellow driver injects transient but horn with compression driver overrides
the dynamics. Of course, to have this configuration you will the yellow driver
and MF horn with a compression driver to be positioned one above the other, not
the way how Aries Cerat did. Here is where all conversations about the advantage
of the Le Cléach profile ends… Anyhow, this is the whole other subject….
