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.
