About the Quatro

The Vandersteen Quatro is a high-end four-way loudspeaker incorporating a powered subwoofer system with two 8" long-throw carbon-loaded cellulose cone drivers powered by a 250W class-B amplifier. It features a 1" dual-chamber coated aluminum-alloy dome tweeter, a 4.5" curvilinear filled-polycone midrange cone, and a 6.5" woven-fiber cone woofer. The subwoofer section includes an 11-band low-frequency equalizer along with level and contour controls to tailor bass response to room acoustics. Vandersteen employs first-order (6dB/octave) crossovers to maintain time and phase coherence, requiring high-quality drivers capable of linear performance over a wide bandwidth. The midrange driver is a patented transmission-line–loaded, curvilinear, mineral-filled polycone designed to eliminate backwave reflections, enhancing transient response and imaging. The tweeter is a tapered, transmission-line–loaded dome of ceramic-coated aluminum alloy, covering frequencies from 5kHz to beyond 30kHz. The speaker measures 43" H x 10" W x 19" D, weighs 110 lbs, and has a sensitivity of 87 dB/W/m with a nominal impedance of 6 ohms. It is The system includes mandatory in-line high-pass filters sold separately. The Quatro is designed for audiophiles seeking detailed, natural, and musically coherent sound with deep, tuneful bass and excellent imaging.
