Classic Audio at RMAF
John Wolff's Classic Audio company has been a fixture at audio shows the past few years, always showing his beautifully made speakers, combining hornloaded midrange and highs with big paper-cone woofers, most recently using field-coilenergized drivers. This year John was demming the T-3.4, which combines a field-coilenergized midrange unit, with a 4" beryllium diaphragm loaded by a wooden horn horn with a 2" throat, with a pair of 15" woofers operating below 500Hz, one firing forward, the other at the floor, and a "Ultra-High-Frequency" supertweeter operating above 12.5kHz.
Driven by Atma-Sphere OTL monoblocks via Purist Audio Design cables, with the source a Stahltek Ariaa DAC, the 350 lb T-3.4s sounded better than I was expecting. On the Japanese album Hands from solo bass virtuoso Brian Bromberg, playing "Stella By Starlight," there was something very right about the presentation, perhaps because two pairs of 15" drivers get very close to reproducing the correct intensitysound pressure per unit areaof the original instrument as well as the overall sound pressure level. Yet the system also excelled on a live two acoustic-guitar arrangement of "Stairway to Heaven," from Rodrigo y Gabriela, which didn't have any lows to speak of.
