Revision 6
Even more tune full. Adjusted timing for the bass unit.
April 2019
Revision 5
Improved suspension for the X-over, and adjusted to more a laid back sound. More tune full.
October 2018
I did not think it was possible to make good X-overs inside the stands.
But
I was wrong. Anders
T1 and Space optimisation
T1 is now "measured for space optimisation" and
works even better with "Space". For best result - ask your Linn dealer for help!

The prototype was demonstrated, and many positive comments!

Why handcrafted speakers in solid wood and aluminum?
The short answer: it sounds better.
The long answer is much longer. But we can start with that each piece of material
has it´s own "acoustics" and the easiest way of experiencing this is just to knock
with your fingers on it and it will reply. Some material as solid
wood will "reply" with a sound you could use in music - it is a harmonic sound
with a few overtones. If you do the same test on a MDF board it reminds less
of a musical tone but more like a noise with many less harmonic overtones. A speaker cabinet
with this will interfere with the music in a complex way. The music will loose fundamental
qualities.
Solid wood is also stronger and will not "break into pieces" as a fiber board can
do around screws or inserts for screws. But Solid wood doesn't always look perfect
and needs occasionally some maintenance.
Our goal
The idea with Klångedang is to make you more involved in the music.
Every single tone needs to be as little modulated as possible so
your hearing easy can understand the pitch and the harmonic relation to
all other sounds in the music.
There should also be a minimum of time error between different
frequencies to make the understanding of the music easy.
Why Klångedang makes you more attached to the music?
Klångedang is different to other speakers in several ways:
Mechanical
- Extremely strong cabinet in solid wood.
- Separated damping for vibrations in the cabinet walls and for the
acoustic sound inside the cabinet.
Electronic
- "Direct synchronous serial filter" of first order, phase correct.
- Low loss components.
- Mounted inside the stands with less mechanical vibrations compared to having them placed inside the speakers.
More about the mechanics
A speaker cabinet in solid wood is stronger than a cabinet
in MDF. Solid wood has a more linear damping but the amount
of damping is lower. In most speakers you add damping to the walls of
the cabinet. It means you put the damping where you don't want
any movement. But the damping will only work if you have movement here!
In Klångedang we try to lead the vibrations to dedicated damping units in the in the stands. So the damping is on a low level on the acoustical inside of the cabinet,
as most vibrations in the walls are effectively damped in the stands.
More about the electronics
Most X-overs are parallel - meaning that the full input signal is split into a bass and a treble
section at the x-over, and then are being treated individually. This is good in some aspects but
there can be problem to get the sound synchronous from the different drive units, especially when it comes to transients.
T1 and M2 have the principle "direct synchronous serial filter".
The + input is connected to Treble + and the - input is connected to the woofer -. In other words - in serial.
If the impedance of a drive unit changes temporary during a transient or because acoustic feedback the information
will not be lost to
the same degree as in parallel filter
- it will
instead go to the other drive unit!
To place the X-over in the stands with less mechanical vibrations compared to having them placed inside the speakers is a quite big improvement. All components works more or less like a
microphone! This solution also makes it possible to connect the amplifier "Direct" to the drive units for minimum loss of information.
But even in the stands there is need for mechanical isolation, and suspension of the X-over.
Together these are small details which, when all optimized, make the music simply much more involving.
