The Apogee Duetta mkII loudspeaker uses two ribbon full-range transducers: a midrange and tweeter ribbon measuring 0.8" wide by 47" long and a trapezoidal woofer ribbon averaging 12" wide by 47" long. It offers a frequency response from below 30Hz to 25kHz (-3dB) with a nominal impedance of 4 ohms and a maximum sound pressure level of 106dB at 4 meters using a 100W solid-state amplifier. The crossover slope is 6dB/octave at the crossover frequency, increasing to 12dB/octave about two octaves away, and it can be biamped with or without an external active crossover. The speaker measures 58" high, 26" wide, and 3" deep, weighing 95 lbs each, and was available in grey or taupe finishes. The mkII revision included a slight canting back of the mid/tweeter ribbon for improved vertical dispersion and a compound crossover circuit for better tonal balance and compatibility with compact disc sources. The Duetta mkII is praised for its powerful, fast, and articulate bass that extends deeply to around 30Hz, exceptional mid and upper bass detail, and a vivid sense of tonal color and instrumental separation. It is no longer manufactured.
