| The 20M is a time coherent, point source, first order, two-way acoustic suspension loudspeaker system that was first introduced at the 1994 Consumer Electronics Show in Las Vegas, Nevada, USA. The current 20M is the result of years of research, innovation, and independent thinking, that have yielded many evolutionary refinements. As a result the 20M has exceptional ability to accurately reproduce music and to retrieve the ambiance of the musical performance.
As proof of the "rightness" of the design, there is no known loudspeaker that can image better than the 20M.
Several features contribute to the performance of the 20M. The 20M's combination of time coherent, point source, first order, two-way, acoustic suspension designs coupled with innovative cabinet and crossover designs and accurate voicing, make the Model 20M incredibly true to the source
As a result of its time coherent, point source, coincident driver array, the woofer and tweeter have identical acoustic centers and identical directivites at the crossover frequency. This produces a stable axiosymmetrical radiation pattern with smooth power response.This is further enhanced by a high quality minimalist four element first order crossover network.
The cabinet of the 20M is finished in real walnut wood veneer. It is elaborately braced and the rear panel is sloped two degrees to eliminate box resonances and colorations. Furthermore, the vertical edges of the cabinet are accentuated with exotic Peruvian walnut hardwood inserts that are rounded to prevent sonic refractions and to enhance the appearance of the 20M.
