Rare wooden midrange horn made in small quantities by YL Acoustic. This was reportedly Yoshimura San’s personal favorite horn, but production was limited because of how labor intensive it was to construct. When used with YL, GoTo, Ale or Western Electric midrange drivers it produces a warm, naturally dynamic sound YL is known for. The (single) horn is shown pictured next to my speaker using the more common MB150 for size reference. The 555 driver is sold separately, but I will consider offers for a package deal. There is another identical horn currently listed on eBay (with a 555 driver).
