Monolith Series

Three-Way Planar Front Passive Loudspeaker

Monolith is a unique, high-performance, 3-way passive, 200W, free-standing stereo loudspeaker system, intended for high-fidelity stereo playback applications.

Built to resemble a beautiful wood instrument or work of art and resting on a solid natural-stone base pedestal, Monolith’s solid enclosure has no grills, no exposed drivers or any other visible indications that it is a superb sounding loudspeaker.

Monolith’s sonic performance is quite surprising – you’ll be impressed with the open sound, dynamic range, spacious panorama and broad listening sweet spot. Since sound converges at the face panel on Monolith and then radiates to the listener instead of firing through a grill, response is very smooth throughout the coverage pattern, avoiding many of the off-axis tonal variances typically associated with traditional speakers. Monolith’s unique abilities are a direct outgrowth of Stealth Acoustic’s LineaResponse™ planar-front radiator technology that combines sound from hidden drivers onto the solid front surface. The results are sound rivaling top-shelf grilled freestanders and unique artistic looks. Monolith incorporates four, direct-tofiber neodymium midrange motors, and one direct-to-fiber neodymium high-frequency motor aligned in Stealth Acoustic’s all-new Quad-Balanced Midrange Drive™ configuration. Advanced internal carbon fiber materials allow for smooth high-frequency extension to 20kHz, while dual high-power 8” cone woofers and optimal bass driver placement provide deep and warm bass response.

To ensure long-term reliability and performance, Monolith contains three independent protection circuits (low, mid-range and high frequency sections) that automatically reset upon reduction of excessive amplifier power.

Monolith is both beautiful art and a whole new paradigm in loudspeaker design, worthy of world class listeners who care about aesthetics. The design and aesthetic flexibility of Monolith is impressive. In addition to exotic hardwood finishes Monolith is also offered in a satin white finish as well as a paint grade version allowing for custom painting to match the decor of the environment in which it will be used. Also, through the use of Stealth Acoustic’s large-format high resolution printing, virtually any image can be produced and applied directly to the face of the Monolith, allow it to literally become a palette for the artistic ideas and goals of its owner.
