Above: a very nice and\u00a0clean looking original Duettas (low serial number) painted in colour “Historical White” of “Painting The Past” paint. The owner told me that the choice for this colour was WAF-induced, but I must say I quite like this serene look. The crossovers have been rebuilt and are in same colour boxes behind the speakers.\u00a0The owner even his own amplifier and also painted it in the same colour. The heating vent in the floor hides a subwoofer using the 15.000 liters basement.<\/p>\n

The original Duetta was built with steel angle iron bracing top and bottom of the rear section like the Scintillas, and a simple 6dB\/octave crossover and too attenuated at the top end apparently making them sound dull.<\/p>\n
The “Duetta” is a mid-size two-way full-range ribbon speaker. It utilizes ribbon transducers for both the midrange\/tweeter and the woofer. The use of ribbons in both elements provides exceptional benefits over the entire music spectrum.<\/p>\n
The two-element woofer and midrange\/tweeter ribbons coupled with internal seamless crossovers provide:<\/p>\n
Features<\/strong><\/p>\n A trapezoidal woofer ribbon designed to provide a broad nonresonant frequency response.<\/p>\n A unique narrow combination midrange\/tweeter ribbon.<\/p>\n Extremely low mass permits almost instantaneous acceleration for unexcelled transient response.<\/p>\n These techniques afford a combination of unprecedented power and clarity along with excellent imaging and soundstage.<\/p>\n Specifications<\/strong><\/p>\n 1986-1987<\/p>\n Original Retail $2300<\/p>\n Height 147.3 cm<\/p>\n Width 66 cm<\/p>\n Impedance 4 ohms<\/p>\n Bass driver Midrange Max Sound Level Frequency response Suggested amp power Weight Finishes available Virtually identical to the original Duetta and structurally the same as Duetta Signatures apart from the cover and stands. The original Duetta was based upon the technology of the Full Range and Scintilla. It was Apogee’s first attempt to provide a smaller, less expensive speaker. Like the Scintilla, it provided a very detailed sound, not universally admired.<\/p>\n According to Alvin Gold, Leo Spiegel said that one of the purposes of the II’s revisions was to make the Duettas more sonically compatible with compact disc. The II is, therefore, softer and less detailed, which was also not necessarily to everyone’s preference.<\/p>\n Specific changes from the original model:<\/strong><\/p>\n There were at least two different versions of the Duetta II. The early ones had an efficiency 4 dB lower than the later ones (106 dB vs. 110 with a 100-watt amp). The later ones also had considerably extended high-end response. The early ones were too limited on the top end, according to some.<\/p>\n Original Duetta<\/strong><\/p>\n Duetta II<\/strong><\/p>\n Can be considered the transitional version. Same speaker platform as the original Duetta, improved, basically a Signature without the final crossover.<\/p>\n Duetta Signature<\/strong><\/p>\n Same basic topology as the Duetta II, but with a major crossover redesign. This final version has much better tuning to achieve better matching between the bass ribbon and MRTW, and more refined crossover-region\u00a0behavior.<\/p>\n Duetta Exclusive<\/strong><\/p>\n The Duetta Reference was a bespoke edition for the German market. This was actually a Duetta Signature with only one small modification in the crossover. The only difference is the addition of a single capacitor, which can easily be removed without further changes to restore the standard Duetta Signature sound.<\/p>\n Extensive Duetta Signature Review<\/a><\/p>\n All models overview<\/a><\/p>\n Listening Sessions overview<\/a><\/p>\n Timeline and History<\/a><\/p>\n FAQ<\/a><\/p>\n
