Bill Fitzmaurice Omni 10, built around 2009 from 22mm ply by a BFM franchised and ex BassChat builder, so it's solid as the proverbial outhouse.  I've long forgotten what driver is in this, and the messages between myself and the builder disappeared in the migration from the old Basschat site, but it's a decent one. These are great for double bass and also work well as tops for a small PA - but you'd need to find a second one!   The cab has mostly been sat in the rehearsal studio
