Thorough maintenance was carried out, from exterior polishing to oil finishing, and from saran net cleaning to the unit network. MODEL 3401 is popular for its gorgeous construction unique to the bubble period. There is a balance between the overhang and voluminous low range that comes out of the 40cm woofer and the mid to high range with a high sense of speed at a really high level. It's a gem that makes you feel very particular about just one wooden horn. Serial 00201V/00204V (Yonejima Satoshi)
