Foreword
You may have heard of Isophon speakers and good feedback of them. For a short
time ago, Isophon was renamed Gauder Akustik, and even for a shorter time ago,
TL Audio decided to import Gauder speakers in Finland. Mr. Tapani Lappi, a chief
in TL Audio, is well-known as a demanding audiophile and as a friend of big
and accurate sound. If he decides to take an import, the product must be good
and certainly has a couple of specific strengths. Lately, I had an opportunity
to make a short test of Arcona 40, which is the smallest one in the Gauder’s
Arcona-series.
I listened to Arcona 40 in TL Audio’s listening room with Devialet 170
amplifier, Olive music server and Bertram signal cabling. The room was slightly
too big for the speakers and this naturally affected more or less the evaluation
of the sound. Anyway, the effect was much smaller than expected! Tapani had
setuped the system carefully and had burned the system in for a couple of weeks,
but referring to his attitude, not quite enough. I trusted to Tapani’s
positioning of the speakers and actually did not see (~heard) any reasons for
further adjustments. Unfortunately again, my session was quite fast and took
a bit less than two hours. Anyway, very well-known music samples, partner equipment
and listening room enabled making solid and deep enough notifications.
Technology
Arcona 40 is a two-way stand loudspeaker. Its sealed and very dead enclosure
tapers slightly to the rear and has excellent WBT-Nextgen binding posts. For
Arcona 40, Gauder has chosen an Air Motion Transformer (AMT) for high frequencies
and a 7” Accuton ceramic cone for the midrange and bass. The cone is mounted
very rigidly into the box, partially by the help of an aluminum membrane. One
of the Gauder’s fingerprints in their speakers is using complex and highly
sloped crossovers. This is true for Arcona 40 as well. By the help of this and
the AMT treble driver’s high power reserves, the dynamic range of the
speaker has been widened remarkably. As a load, Arcona 40 is quite demanding,
requiring a powerful and stable amplifier – namely, the impedance drops
to 2.4 ohms in the bass region. Based on the principles and size, the speaker
is recommended into rooms sized up to 25 square meters.

Listening
After the start, I was quite soon struck by the resolution which the Arconas
were capable of delivering. That was not done by cheating, for example by treble
emphasis, but due to the high quality speaker design, which enables reproduction
of the rapid dynamic contrasts even in the very low level. Besides this, the
articulation of the melodies was also crisp and precise, rendering a good phase
control. Quite a stunning start of listening!
The balance seemed to be slightly on the bright and lean side, which surely
grounded partially on the big listening room. Nevertheless, the level of the
defect was absolutely not intrusive or disturbing, and some music samples delivered
still very natural like timbres of instruments. I’m quite sure that the
final neutrality will be more dependent on the partner equipment and room acoustics
than this kind of tendencies of the speaker. So, Arcona 40 was absolutely neutral
enough.
The speaker sounded also very consistent all through its bandwidth capability.
The bass passages were at least almost as accurate as razor sharp piano and
guitar notes, including their harmonics. The bass was also quite extensive and
very well controlled when played in limits of the recommended dynamic range.
Although the midrange seemed to be a bit more prominent than the bass, both
bands had the same kind of punctuality and clarity. Nor did the treble make
a disappointment. It was surprisingly open and all the cymbals, chimes and triangles
sounded very natural. Actually, the presentation was the best I have heard from
the AMT tweeter.
The speakers of this size are usually quite restricted in maximum dynamics.
Anyway, Arcona 40 could spit out quite impressive volume levels without significant
distortion and clipping. In my listening, I turned the volume approximately
up to 90 dB and the sound was still clean. Actually, there are plenty of two
way speakers which would have reached their edge performance a long before this
point! Still, for my personal listening purposes, Arcona 40 has slightly restricted
dynamic resources. But, if you can live with a little less, Arcona 40 does a
solid fulfillment also in this feature.
With my music samples, the Arcona 40 rendered superb transparency and plenty
of air, focus and dimensionality in its sonic view. With certain bigger speakers,
you will find more extensions, especially vertically. However, this will be
achieved at a price. Arcona 40 is a speaker which sounds bigger than commonly
presumed, definitely!
Summary
I really liked a lot of the performance which Arcona 40 delivered during the
listening. It showed its nature with no excuses, to which it actually has no
reasons. Besides its very high sound quality, owners will enjoy tremendous finish
and use of the speaker. Arcona 40 costs 2000 euro/pair which is double of the
price of Epos Elan 15. As good as Epos Elan 15 is, the Arcona 40 is a better
speaker. Of course, if it is actually better enough, must be considered individually.
As a whole and with my preferences, Arcona 40 is so far the best speaker I have
heard in this price range. I could swear that after the Arcona 40 and other
Gauder Acoustics speaker’s income, the hard speaker competition will be
even harder in Finland.
