Markaudio-SOTA Cesti B, all-range symmetric driver loudspeaker technologyDale Davies ▼ | August 23, 2019
The Cesti B is Markaudio-SOTA medium size 2-way loudspeaker utilizing their custom all-range symmetric driver technology to create a full range loudspeaker.
Audio A minimalist control network complements the custom drivers
MarkAudio-SOTA’s unique dual-driver, all-range approach offers the rich midrange that is typical of a wide-range single speaker design, while providing a full frequency range extending from 40Hz to 25kHz, and the high-impact dynamics of more typical multi-way speakers. Using a custom-designed, 110mm (Sota 11) wide-range acoustically-isolated mid-bass driver, with a 50mm (Sota 5) tweeter, the drivers’ low mass mixed-alloy cone provides transparency and detail.
MarkAudio-SOTA uses its own symmetrical technology. The dual, wide dispersion, shallow-profile cone drivers replace conventional cone-woofer and dome-tweeter combinations. With their matched dispersion and output characteristics, along with a minimal crossover slope, the two custom-made Sota drivers provide an audibly seamless integration between high and low frequencies. This integration results in a smooth, natural output and soundstage that affords a wider range of seating positions, allowing several people to hear a top quality performance at one time.
All Cesti enclosures are constructed from high-density fibreboard giving maximum acoustic stability. The rigidity and mass of the panels are carefully balanced to avoid audible resonances and provide our custom drive-units with a solid platform. The Sota 5 high-frequency driver is isolated in its own sealed sub-chamber. The Sota 11 bass-mid works in the main vented enclosure volume. The simple but elegant crossover design progressively transitions the higher and lower ranges of the audio signal to the driver optimized to handle that part of the spectrum ■
