The new 1723 S speakers are a direct supplement to the
1723 Series. They are built to the same quality level and
have the same feature and core parts as the rest of our
critically acclaimed Arendal Sound 1723 speakers. The
goal with 1723 S was to add a matching set of smaller
sized speakers, which would seamlessly match the 1723
Series without any form of timbre matching issues
whatsoever. Not everyone can have the larger 1723
speakers with the big 8” drivers in their living room or
in tight spaces. We have been asked hundreds of times to
introduce a smaller speaker with the same qualities as
the 1723 series. We did deliver and we are very happy to
announce the 1723 S speakers. S for Small.
A key requirement was that the 1723 S speakers should
match the 1723 lineup allowing customers to mix and
match within the same series without any bottleneck
factors. If you have a pair of 1723 Tower and do not
have the space for a 1723 Center and 1723 Surrounds,
Center S and Surround S will be perfect alternatives.
The 1723 S speakers are smaller, with same quality and
timbre match as its bigger brothers.
S FOR SMALL.

I was born and raised in Arendal 1978, Norway. As a kid I
enjoyed many activities, such as catching fish for my cat
Johnas, riding my bike, playing football and video games,
and hanging out with friends. Of course not a day went by
without wrestling with my older brother Dan Benny.
My dad, Jan, founded an electronic store in the 70´s and it
quickly became the top selling store of it’s kind throughout
Norway. On a good Saturday it was not unusual to sell
40-50 color TV’s, which were hot tech at the time. Today
he spends his elder days as a fisherman, just like my
grandfather Olav before him.
During my younger days there was rarely a weekend when
I was not (somewhat reluctantly!) dragged out of bed on
a Saturday morning to help sell my grandfather’s catch
from the night before to the neighbourhood. I was often
told “your grandfather has caught a lot of fish, you need
to help him sell it”. Dragging all the fish with me, I walked
several kilometers and knocked on many doors utilizing
some maybe desperate sales tactics to charm the older
ladies. My customers may have felt sorry for me seeing
me walk around with fish, but I was able to sell them and
returned home with pockets full of money. My grandfather
gave me a cut of the sales so I could buy candy and save
the rest in order to purchase more audio products. These
were some of the best memories of my childhood.
As you may have guessed, I was introduced to the audio
world at a very early age. When I turned 14 I started to
work part time at my dad’s store. When your hobby is
electronics and you work in such an environment you
get the urge to purchase and test as many products as
you can, which I did with great joy. Normally, instead of a
paycheck, I brought home new speakers or amplifiers that
had to be tested. My very first setup was a stereo system
with some huge speakers which could play very loud.
It was hugely annoying to my mother. Does that sound
familiar?
It’s one thing to have fun with audio equipment, but
another very different thing to understand it. I studied
electronics for 8 years, graduated from Grimstad with an
engineering degree and was lucky enough to get a job in
the oil industry. After working in the oil industry for a
while, I knew that it wasn’t the field for me. Audio was my
passion and that’s what I wanted to work with.
With 15 years of business experience in the audio industry
and after shipping tens of thousands of audio products
throughout Europe and beyond, I wanted something else.
Something of our own which had been lingering in the air
for many years. At our 10th anniversary, what better way
to celebrate and continue the story, than with the release
of our own speaker brand?
The idea of Arendal Sound was born.
It was no coincidence. We’ve spent years researching,
listening to our customers, planning, developing,
engineering and investing in Arendal Sound. I always
wanted our team to have something to be extraordinarily
proud of and enthusiastic about. It had to be something
that was based on solid acoustic engineering principles
STORY OF ARENDAL

and yet aesthetically beautiful, surrounded by a unique
story - ours. Arendal Sound builds upon traditional and
historic Norwegian elements, where solid craftsmanship
and finish quality are a top priority, backed with pleasure
in the use and pride in the ownership. We even want to
show our beautiful country to our overseas customers and
invite them to Norway.
We areafamilyand team with the same mentality and goal,
to create market leading products, packed with incredible
value, backed with our highly acclaimed customer support
that extends beyond the date of purchase.
To me, business comes second and at the end of the day,
it’s my family who are most important. Without them it
would have been hard. I would especially like to thank
my wife, Heidi, as she has been by my side all this time
showing extreme patience and understanding. And of
course my two little kids, Marcus and Leander, they are
the dessert in life as my mom and dad say.
We hope you will enjoy our products as much as we
enjoyed making them.

The 1723 Tower S is a downscaled version of the 1723 Tower.
It features a completely custom built 2.5-way lineup of
mid-bass drivers and a waveguide tweeter you cannot find
anywhere else. The materials, quality, drivers and crossover
components are just the same as you would expect from
any of the 1723 speakers. The only difference is smaller
enclosure with 6.5” drivers in 1723 Tower S, instead of the 8”
in the 1723 Tower. The sheer performance, level of detail and
dynamics delivered by Tower S is unheard of in this price
category. Expect the Tower S to be compared to much higher
priced speakers on the market.

The 1723 Center S is a downscaled version of the 1723
Center. The speaker is identical to 1723 Monitor S, but sold
singly and with the grill badge moved for aesthetic purposes.
This makes sure that you will have 100% timbral match
when using it with any of the 1723 speakers like the Monitor
S and Tower S which are sharing the exact same core
MTM design. The materials, quality, drivers and crossover
components are just the same as you would expect from
any of the 1723 speakers. The only difference is smaller
enclosure with 6.5” drivers in 1723 Center S, instead of the

The 1723 Surround S is a downscaled version of the 1723
Surround. The materials, quality, drivers and crossover
components are just the same as you would expect. The only
difference is smaller enclosure with 6.5” drivers in 1723
Surround S, instead of the 8” in the 1723 Surround. Using
the same 6.5” mid-bass driver and waveguide tweeter on the
front baffle as used in the other 1723 S models, excellent
tonal matching is assured. To deliver an all-enveloping
surround field and assist in peerless surround steering, we
fitted custom built 4” full-range dipolar drivers to the angled
side baffles into our TriAxial speaker. The 4” surround drivers
are imported straight from the original 1723 Surrounds,
as this driver is optimal for the task, regardless of the main
driver size. The sheer performance, level of detail and
dynamics delivered by the Surround S is unheard of in this
price category. Expect the Surround S to be compared to
much higher priced surround speakers on the market.

Rock solid HDF cabinets
Higher density and naturally better damped than MDF
(Medium Density Fiberboard), using HDF (High Density
Fiberboard) results in a sonically inert cabinet. HDF was
also chosen because it can be machined much more
precisely than MDF, which is especially important for
precision critical areas like the two part HDF & Aluminum
waveguide.
Arendal Sound products are using HDF thicknesses
ranging from 18 to 50mm throughout the designs, with
critical areas like driver mounting and cabinet bases
being the thickest.
Internal bracing has been strategically placed to increase
overall cabinet strength and limit unwanted panel
vibrations that may cause audible colorations. Internal
braces are CNC routed to shape to smooth internal airflow
and minimize volume losses within the cabinet, whilst
maintaining thickness at critical assembly joints.
The final detail for 1723 Tower, Monitor and Center, is to
apply a butyl based differential mass damping layer to the
inner faces of the cabinet, just to be sure we have damped
out every last resonance in the large enclosures. Butyl
is not added for 1723 S speakers as these have smaller
enclosures and did not give any differences in testbench
measuring or audible differences.
Magnetic metal grills
We are especially proud of our new exclusive and fully
custom made grills. For all Arendal Sound speakers we
have made a free flowing, perforated metal grill which
does not affect sound quality. We have then wrapped it
with a clean black cloth to tone down the visually hard
look, whilst simultaneously damping out any residual
vibrations.
In addition, we did not want plastic pins to add the grill,
which will degrade the clean look of the cabinet with pin
cups. Neodymium sub-surface magnets grip the metal
grill with great force, preventing unwanted movement
and vibration during high level playback. The grills have
a rubber protection to ensure the cabinet is not damaged
when you attach the grill and you will hear a nice ‘thump’
when you let them seat. Grilles on or off, our speakers
look and sound great either way.
PREMIUM BUILD QUALITY
Premium Finishes
All Arendal Sound 1723 speakers comes in four premium
finishes;
• Black Satin
• Black Gloss
• White Satin
• White Gloss
To ensure the best and long lasting quality, all Arendal
Sound speakers use up to 12 layers of paint, consisting of
primers and polyurethane paint, hand finished. We use no
vinyl, anywhere.
The finish is what you would expect from Hi-End products.
No plastic - “Green sound”
Well, you may find a cable strap somewhere in plastic,
but all components in Arendal Sound which affects the
sound are built up from non-plastic parts. High grade
aluminium back plates on subwoofers and speakers. Even
our logo is in anodized aluminium.
Internal wiring
Not your average zip cord. All products utilize high count
multi-strand wire, braided together. These were not done
for looks, but chosen to produce the most consistent
impedance possible and electrical current carrying
capabilities. The benefit is very low insertion losses
without the problems of “skin effect” caused by large
diameter wires. This insures that each driver sees what
the amplifi er intended without additional colorations.
Rubber feet
All subwoofers comes with rigid rubber feet (M6 threads)
which have a strong grip on the floor. You will not have a
subwoofer walking around, even if that is impossible due
to the sheer mass of our HDF cabinets which are “super
quiet”. Put your hand on our speakers whilst they are
playing and you will feel, very, very little.
