A compact horn loudspeaker. Isn't that an oxymoron, like jumbo shrimp, or military intelligence? From such venerable speakers as the half century-old Altec Voice of the Theater and the Klipschorn, as well as more modern examples like the Avantgarde Acoustic Trio, horns have always been big. The original Avantgarde Uno was the smallest speaker in Avantgarde's line, but it was still visually imposing, with a big horn midrange on top, a horn tweeter below that, and a powered sealed-box subwoofer at the bottom. (I reviewed the Uno 2.0 in Stereophile
in August 2000
, Vol.23 No.8, and the Uno 3.0 in August 2002
, Vol.25 No.8.) The Uno and its siblings, the Duo and Trio, are perhaps the antithesis of the in-wall loudspeakers beloved by interior designers. These speakers do not fade into the backgroundnot visually or sonically.
