Isis

About the Isis

Avalon Acoustics' Isis Signature represents a pinnacle in loudspeaker design, combining advanced materials and proprietary technologies to achieve exceptional musical accuracy and three-dimensional dynamic sound. It features a three-way, four-driver configuration with a 1" concave diamond diaphragm tweeter, a 7" concave ceramic midrange driver, and two 13" Nomex Kevlar composite woofers with low-Q magnetic structures. The speaker employs Avalon’s Silent Inert Composite system to eliminate cabinet resonances and uses proprietary all-phase, high-current crossover networks with custom-smelted precious metal conductors for optimal linearity and headroom. The low-frequency impedance is flat and free of system resonance, making it easy to drive with recommended amplifiers from 50 to 500 watts. The cabinet is carefully shaped for three-dimensional staging and vibration damping, ensuring pure pistonic driver behavior without diaphragm break-up modes within 70 dB of the signal. Dimensions are approximately 60" (152 cm) high, 14.5" (37 cm) wide, and 17" (43 cm) deep, with a weight of about 89 kg (195 lbs) per speaker. Available finishes include Birdseye Maple, Satin Dark Polychrome, Quilted Cherry, Curly Maple, and Figured Walnut, all with premium deep gloss options. The Isis Signature is noted for its astonishingly low distortion, neutrality, and superb imaging capabilities, making it a flagship model in Avalon’s lineup.
