Visioneering Design has completed a demo screening room for its Tesseract high-power, three-way, tri-amplified loudspeaker systems designed and TMH-qualified by Tomlinson Holman, which will be used in professional screening rooms, dubbing theaters, film and digital cinema theaters, and high-end home theaters. The systems are manufactured by Visioneering Design (Chatsworth, Calif.), founded by Ron Lagerlof.

Central to the Tesseract LMH-1 loudspeaker system (pictured) is a Tomlinson Holman custom-designed crossover, dividing the main screen channels into low, mid and high-frequency outputs to feed the tri-amped L/C/R speaker cabinets. The screen and surround outputs are passed through the "Inverse EQ" filter, allowing for flat response in "noncinema" playback mode. High-quality components are used throughout, including Dynaudio and Electro-Voice drivers and THAT Corp. differential input amplifiers in the crossover for superb CMRR rejection and extremely low noise.
