Reduction does not always mean just leaving out.
Reduction often means creating awareness for the
essentials. Or simply: concentration. The DUO SD
with single drive bass unit is the concentrate of
what makes a loudspeaker the perfect entry into
the 'classic sound' of the DUO series.
Carefully minimized in the outer dimensions,
superiorly improved in its technology.
For a maximum Avantgarde listening pleasure.
