Capital AudioFest 2011

Classic Audio Loudspeakers' John Wolff, along with his red shirt, the parrots that perch on his speakers, and the reproductions of Nipper he offers for sale, is a fixture at regional audio shows. When I asked him about this, he responded that he believes regional shows are the future of this industry. John was using Atma-Sphere tube electronics, including M-60 monoblocks, to drive his 4'-tall T-3.4 speaker, which uses a wood radial Tractrix midrange horn fitted with a 4" beryllium-diaphragm compression driver firing into a 2" throat, coupled with twin 15" woofers—one firing forward, the other to the floor—and a supertweeter. The midrange unit and woofers all use field-coil–energized magnets.
