Viotti One is our flagship 2-way stand-mount loudspeaker utilizing custom all-range symmetric driver technology to create a full range loudspeaker. A minimalist control network complements the custom drivers, delivering music to the listeners while minimizing artificial processing. Laminated dual-core panels and polymers provide enclosures of maximum strength and acoustic stability. The result is statement-level sound quality for the discerning listener.
Viotti One loudspeakers are built from the ground up, including the cabinets, crossovers and speaker drivers. Many manufacturers choose off-the-shelf components that aren’t always a perfect match to their system design targets, MarkAudio-SOTA, purists by engineering standards, build their components to precisely match the specific design characteristics of the speaker systems. “Hear Our Difference” is the technical application to hi-fidelity performance.
Viotti One was styled by Andrea Ponti, an Italian designer who works extensively in Europe and Japan. Andrea's concept for Viotti One blends the fluid curves of 1950s modernism with cutting-edge wraps for an elegant, minimalist look. Viotti One is available in four luxurious lacquer finishes: light oak, dark oak, white piano-lacquer and black piano-lacquer. These are true lacquer finishes, with seven hand flatted and polished layers for a deep shine.
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 30kHz, 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.
Viotti One 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. Our shallow waveguides are CNC machined into the front panel. The size and profile of these are designed specifically for the Sota drivers to maximize positioning flexibility.
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. The 2.4 kHz crossover frequency uses gentle 2nd order electrical and acoustic slopes that gradually blend the outputs, maximizing the advantages of our symmetric wide-dispersion drivers. The simple design, with few reactive components, also aids in amplifier matching, allowing MarkAudio-SOTA speakers to be easily driven by low-power designs. The result is a 2-way loudspeaker without any obvious crossover transition, and a smooth, transparent but dynamic and natural musical response.
