Introduction
The Strandberg C50 is a classical designed floor standing speaker with the latest
drive units technology. The goal is to make an uncomplicated sound that is easy to
listen to that respond well to the smallest input signal.
To achieve this we use one larger mid-woofer with low mass, instead of many small
drive units. In this way we get more physical feeling of lower frequency than just
the deep tone. The balance between what we hear and frequency measurements
will be more correct. In other words we get more body in the sound.
Drive units with light cone is also easy to drive with a small amplifier. The larger
cabinet size will make low cone mass mid-woofer breathe natural with less
compression. Then we will have deep clear un compressed natural bass.



Design details

Cabinet
The cabinet is tuned to make a natural roll-off without any ringing in step
response. Cabinet are made of MDF-board with internal damping pads for
minimising cabinet material resonances. Cabinet is heavily braced to give stiff
cabinet and the damping pads make it non resonant so the cabinet don’t store
sound in the time domain. Natural wool is used for internal acoustic damping
because it sond best and have a wider frequency damping of the internal sound. It
is loose packed so we don’t store sound in the damping material. We use
minimum damping material and apply it where it do the most use, in centre and
middle of the cabinet were air speed is at it maximum. Then we can apply
minimum damping material to achieve maximum damping of the internal sound.

Crossover
The 2 way crossover is hardwired with high-end Mundorf capacitors and baked air
coils to avoid any internal component and filter resonances. The secret with
crossover design is to make the driver to play together without pushing any drive
unit over the comfort zone. So we have to consider the cone area together with
drivers material behavior. The result is seamless transition between mid-woofer
and tweeter over the crossover point and throughout the entire frequency range.

Drivers
The 8” mid-woofer and tweeter drivers have been specifically selected and custom
developed by industry renowned driver manufacturers and offer the latest in 21st
century advanced driver technology. The 8” mid-woofer driver with titanium voice
coil former and its built-in copper rings in the magnet system offers high
symmetric drive suppressing intermodulation distortion. Low losses and large
window in the chassis to reduce reflection air noice resulting in industry leading
high-end voice handling and astonishing micro/macro dynamics in its hole
frequency range. Likewise the 30mm wide surround waveguide tweeter offers time
alignment superb vocal rendition and excellent imaging at listening positions. The
30mm tweeter is a perfect combination to the 8″ mid-woofer. With the lager cone
area it meets the mid-woofer in natural way and make the two driver behave like
one music source for the listener. Tweeters large surround, built-in copper ring
and textile dome diaphragm provides a flat frequency response above 30 KHz.
Large rear acoustic chamber give low compression and move tweeter system
resonance far from crossover point.
