These very speakers are now the property of my listening buddy JW and they’re set up in my listening room for extended evaluation. They wil be compared to Magnepan MG3.6R and MG20.7. An extended review, comparing 3 sets of Duetta Signature (including a refurbished set) can be found here:<\/p>\n

And this is how the refurbished Duetta Signature looks – quite impressive, don’t you agree? You only need to be careful with the fully exposed ribbons…<\/p>\n

Generic Info<\/h2>\n

The second revision of the original Duetta was a visual and electrical redesign, the front lip of the Duetta cover was removed to give a tidier appearance, and sturdy aluminum feet were added. The crossover was redesigned to enhance the high-frequency response, along with the addition of a three-position mid\/tweeter level switch.<\/p>\n

According to reviewers, the signature greatly improved the Duetta II’s bass performance, produced clearer high frequencies, and was less prone to sounding bass-heavy.<\/p>\n

When it was released, the Signature offered exceptional performance to the lucky few who could afford it, along with the necessary amplification.<\/p>\n

It likes to be well clear of walls 3-4 feet from the back wall, and at least 1-2 feet from the side walls, which helps imaging greatly.<\/p>\n

Duetta Reference<\/h2>\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

DAX 3 (optional)<\/h2>\n

\"Apogee<\/p>\n

A DAX is a two channel Dedicated Active Crossover designed specifically to be coupled with the Diva, Duetta Signature and Caliper Signature, or Mini Grand and Studio Grand speakers. A DAX provides exceptional tuning flexibility which enables users to sculpt a tonal balance to meet their listening requirements whilst skipping part of the passive crossover components. The DAX will accomodate a wide range of preamplifier and amplifier characteristics. There were various DAX versions, click the link below for more info.<\/p>\n
