(per pair)

Viotti Tower is our flagship 2-way 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.


Built From The Ground Up
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.
All-Range Driver Approach
Viotti Tower uses custom high-performance driver units; the custom built Sota 11 x 3 pcs and Sota 5 x 2 pcs. Designed by Mark Fenlon, the British engineer who created the internationally acclaimed Alpair product range, they are true wide-range drivers. Both can reproduce bass notes, and have high frequency extension beyond the upper limit of human hearing.
Symmetrical Sound Field
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.
Advanced Cabinet Engineering 
The Viotti Tower cabinet uses advanced dual-core laminate construction to optimize the stiffness and mass of the structure, eliminating unwanted panel resonances.The driver units are acoustically isolated from each other to prevent cross-interference. The smaller high frequency drivers are given its own aerodynamically-shaped sub-chambers, while the larger bass-mid units use the main vented cabinet volume.
The Viotti Tower crossover network is a low-order design using a minimal number of components to reduce electrical interference. It exploits the exceptional range and symmetrical dispersion behaviour of our custom drivers to blend the outputs in a more progressive manner than the steeper crossover slopes often encountered.The crossover components are mounted on a custom printed circuit board with heavy-gauge tracks for minimum losses. Key features are polypropylene-film capacitors with copper wires and two different types of inductor, optimized for their different functions. All components are to exceptionally close tolerances.
Viotti Tower was styled by Andrea Ponti, an Italian designer who works extensively in Europe and Japan. Andrea’s concept for Viotti Tower is an evolution of the Viotti One, which blends the fluid curves of 1950s modernism with cutting-edge wraps for an elegant, minimalist look. Viotti Tower is available in two luxurious lacquer finishes: light oak, black piano-lacquer. These are true lacquer finishes, with seven hand flatted and polished layers for a deep shine
