Since 1977, Vandersteen Audio has designed and built innovative loudspeakers using advanced design concepts. Minimum-area baffles eliminate virtually all cabinet edge and grille diffraction anomalies while mass alignment of driver elements insures proper time arrival. Vandersteen Audio was the first loudspeaker manufacturer to use the Gen-Rad 2512 FFT (Fast Fourier Transform) Computer Analyzer for in-house research and development and remains a leader in interfacing complex computerized analysis of loudspeaker parameters and performance with practical design and engineering.
The Model Three benefits from our years of experience designing and building loudspeakers of unparalleled value and performance. It couples proven technology with advanced materials, construction and design for a speaker system that is always true to both science and music. The Model Three is completely upgradable. As future improvements in technology and/or materials enhance the capabilities of the speaker, cost-effective updates will be available to upgrade existing speakers to the latest components, performance and specifications.
THE ACTIVE COMPONENTS
With our experience in FFT computer analysis and extensive research into the negative effects of diffraction, we developed a unique, proprietary midrange driver (Patent # 5073948) that outperforms previous designs in several significant parameters. In conventional cone midranges, the acoustic energy from the back of the cone immediately strikes the front of the driver's magnet assembly and is reflected back through the cone and into the listening room. This distorted secondary signal created by the internal diffraction smears the sound of the driver and inhibits true transparency. The frontal area of the magnet assembly on the Vandersteen midrange is minimized through the use of advanced materials and construction techniques to reduce internal diffraction and the resultant distortion to inaudible levels. With the elimination of this distortion, the sound of the Model Three is cohesive and smooth with a level of inner resolution unequaled by other loudspeakers.
The active acoustic coupler and woofer use costly cast-metal baskets rather than the more common stamped baskets. The cast-metal baskets' inherent rigidity and superior vibration control increase cone movement accuracy and resist sympathetic resonances for cleaner and more natural sound. Filled polycones are used on the woofer and midrange to insure high stiffness, superior internal dampening and greater neutrality than metal alloy, woven plastic or treated paper cones. The stiff, low weight polycones resist flexing under all drive conditions for lower distortion and increased detail.
The dual-spider active acoustic coupler accurately complements the woofer to reduce box loss, thermodynamic loss and active/passive transfer nonlinearities. This novel Electro- Mechanically Optimized Woofer System provides powerful, detailed and extended bass response as the Model Three operates much more closely to the ideal than conventional ported or passive designs.
The crossover is engineered for bi-wiring with a stereo amplifier or passive vertical bi-amplification with two identical stereo amplifiers. Inputs are heavy-duty screw terminals.
The Model Three's enclosure is constructed of 1 to 1 1/2 inch thick MDF, an advanced material that resists vibration and reduces cabinet resonances. Broad-spectrum, low-Q resonances are controlled so as to cancel rather than become additive.
THE ALIGNED DYNAMIC DESIGN
The Aligned Dynamic Design is used for the Model Three due to its many potential advantages:
This dimensional purity is the essence of the Model Threes. It allows them to recreate the music's original scope and passion. You hear deeper into the music and better understand the feelings forming its foundation. You become more involved in the music as its complex inner structure is revealed with increased clarity and realism.
At Vandersteen Audio, we believe that these qualities are fundamental to your enjoyment of your music. We are pleased to have embodied these qualities in a speaker whose simple, but elegant, physical presence complements the decor of your listening room. We are devoted to continue building distinguished loudspeakers that make a statement about the importance of music in your life.
