It is a famous woofer that is also used in the ALTEC A7. The biggest appeal is the low range where the cone paper is lighter than the 515 series woofer and has a sense of volume. You can experience bass with excellent omission, which is particularly penetrating in JAZZ systems, etc. There are slight dents and wrinkles on the center cap. Serial 24767 25601 (Itsuro Mizushima)
