More German Horns: the Avantgarde Duo Grosso
By John Atkinson Posted: Jan 12, 2011
Avantgarde's Armin Kraus stands next to the new version of the three-way Duo speaker, the Grosso ($36,000/pair). Finished in "Lamborghini Orange," the Grosso substitutes two 12" woofers for the Duo's 10-inchers, and drives them with twice the amplifier power. The midrange and treble horn units are the same, but the speaker is now supported by a sturdier space-frame with spikes that are adjustable from above. And again, this is a horn speaker that offers the advantages of hornshigh dynamic range, sensitivity, and "jump factor"without the disadvantages, such as midrange coloration.
