Description
The MB3.5 B works as a 2.5-way speaker, where the two midrange-woofers are supported by two 6.5” aluminum coned woofers. The two carbon midrange-woofers are run in series for increased power handling.
The MB3.5 B cabinet is heavy, braced and curved, with carbon reinforcements. The speaker is crossed over at 2600 Hz and the two added side woofers assist up to 150 Hz.
The MB-series features high quality crossover with top quality components. The filter has been carefully tailored to linearize the frequency region where cone and cabinet geometry play a role and also to carefully tune the speaker to a natural sounding frequency response.

ScansonicHD
Having worked with Raidho speakers for more than 12 years, we found ourselves faced with a completely new challenge when we was asked to design a new range of high-performance speakers for the Scansonic brand.
From the start, we were very focused on building on all the experiences and strengths obtained from designing the Raidho speakers. At the same time, we also had to be aware of the long heritage and the Nordic design tradition of the Scansonic brand. This time, the task also came with a budget and a desire to create the very best possible within financial limits.
It was clear to us from the very beginning, that some core techniques from the Raidho speakers would be of importance: The speakers had to be designed around a ribbon tweeter that works with at super lightweight diaphragm that is sealed around the edges to allow for a seamless transition to the midrange region.
Furthermore, they needed to be designed and developed with a speaker driver with a ridged, pistonic-type membrane, that could keep up with the ribbon tweeter.
Weight loss for resolution transients & superb leading edges
The MB ribbon tweeter has a membrane with an extremely low mass.
It is formed by a Kapton-aluminum sandwich that is only 20 um thick, and the resulting mass is app. 0.03 g., which is approximately 50 times less than any conventional textile, ceramic, beryllium or diamond dome. The lower mass translates directly into higher resolution and less sound coloration.
Weaved carbon cones for stiffness & low compression
For the MB-series, we have developed a ridged, dust cap free, carbon membrane. By carefully optimizing the shape and stiffness, we have succeeded in making a very well performing woofer that blends beautifully with the ribbon tweeter. The woofer has an overhung magnet system, with long linear stroke and excellent bass performance.
