The shallower one is ~13 inchs deep, the deeper one is ~18inchs deep (from memory).
Also from memory, 14 inches deep and the "deeper" one was 19 inches. I had the shallow one, and it was my main cabinet for years, under a tube MMHD150. I wish I had that combination again. Crystal clear yet deep and gawdawful LOUD!!! From what I recall, it was about the same weight as a 4x10 cabinet, but easier for one person to move around.
