Crystal Cable Minissimo Forte Bookshelf Speaker Minissimo

When Crystal Cable launched the original, glass cabinet Arabesque in 2009, the audio world was stunned by the performance of a speaker that sounded as clean and clear as it looked. The Arabesque shape of this groundbreaking loudspeaker was developed to prevent resonance and standing waves and to eliminate parallel walls and common dimensions, resulting in natural resonant decay without resorting to damping materials. This unique design and technology was then further perfected in the following Arabesque speaker models: the Arabesque Mini, the Arabesque III and the Minissimo. Now, the new Minissimo Forte takes things to an even higher level. Crystal Cable’s goal was to further refine the performance possible from a standmount loudspeaker, while maintaining its predecessor’s beauty and compactness. An advanced new passive-active crossover has been added, alongside special fully balanced filter technology. Our unique MAD™ (Multiple Absorption and Dispersion) system and the new stable and decoupled stand further reduce cavity resonances, and improve sound quality. Together, this series of engineering improvements delivers superb sonic performance.

Development

With so much of the design right first time, the original Minissimo stand mount loudspeaker was a hard act to follow. So our engineers thoroughly analyzed the behavior of the loudspeaker using tools like COMSOL™ Multiphysics computer aided design facilities and our custom-made vibration measurement system. The decision was then taken to focus in on three specific areas where further improvements could be achieved, namely the speaker cabinet, stand assembly and crossover.

Developing the cabinet

One key design aim was to take the Minissimo’s cabinet and support stand out of the equation, making them as acoustically inert as possible. This was done by identifying and then eliminating all vibration paths inside the speaker, by the fitment of a special layer of internal resonance-reducing material. This is unique in the field of loudspeaker design, and has further lowered cabinet noise as well as preventing extraneous vibrations between cabinet and stand.

Developing the crossover

For the ‘passive-active’ crossover design, our engineers benefited greatly from the spectacular results achieved while designing the Symphony loudspeaker of sister-brand Siltech, with which Crystal Cable shares all resources and production facilities. Most loudspeakers employ a passive separation filter using coils to provide the drivers with the correct signal, but this can cause non-linearity and dynamic compression of the signal. The passive-active filter used in Minissimo Forte eliminates these limitations by using frequency dependent components, which allows for much greater control of the sound, higher resolution of details in the music, and increases the dynamic range.
