The Avantgarde Duo 2.2 loudspeaker system is a flagship model from Avantgarde Acoustic, designed for audiophiles seeking uncompromising sound quality. It features a 27-inch spherical midrange horn with 18-ohm impedance and 107 dB sensitivity, delivering a wide bandwidth from 170 Hz to 20 kHz. The system uses Omega voice coils and Avantgarde's CDC technology to optimize frequency response and minimize signal path components, resulting in detailed and low-distortion sound reproduction. The Duo 2.2 includes active subwoofer modules powered by 200-watt amplifiers driving dual 10-inch drivers, with DSP controls allowing fine adjustments of crossover frequency (60 Hz to 220 Hz in 5 Hz steps), phase, and volume for perfect integration with the horns. The loudspeaker employs a three-pillar steel tube frame supporting the horns with adjustable height. The midrange horn is asymmetric with a 3-inch hard dome plug and a 7-inch Kevlar-coned driver, while the treble horn uses a 1-inch concave-dome driver with phase correction and resonance-free transmission line venting. The system weighs approximately 100 lbs per speaker and measures roughly 13"W x 19"D x 22"H for the subwoofer enclosure. The Duo 2.2 is praised for its veil-less directness, rich aural colors, superb resolution, and controlled low-20Hz bass extension. It is suitable for both small and large rooms and works well with low to high power amplifiers.
