Duetta Signature

About the Duetta Signature

The Apogee Duetta Signature is a refined version of the original Duetta, introduced around 1988, featuring a 2-way all-ribbon speaker system with ribbon transducers for both the midrange/tweeter and woofer. It includes level controls for the midrange and high frequencies adjustable in three stages, and supports bi-wired speaker connections. The crossover is a passive 6 dB/octave slope with a nominal frequency around 600 Hz, acoustically crossing over near 1 kHz. The bass driver uses an aluminum/Kapton diaphragm with tension springs to reduce distortion. The speakers have gold-plated five-way binding posts for separate bass and mid/high inputs, allowing bi-amping or single amplifier use. The Duetta Signature was praised for improved bass performance, clearer highs, and a tidier appearance compared to earlier models. It requires powerful amplification (recommended 100W into 8 ohms or 200W into 4 ohms) and careful placement away from walls for optimal imaging. Typical finishes include light grey, anthracite, taupe, faux marble, or black sand. Each speaker weighs about 120 lbs (approx. 43 kg) and measures approximately 150 cm tall by 72 cm wide and 8 cm deep (excluding base). The maximum sound pressure level is around 105-115 dB peak at 4 meters, with a frequency response from about 30 Hz to over 20 kHz. It is no longer manufactured.
