Got an email from Marc early last week saying my cab (BL212) had shipped that day. Had it in 2 days! Great shipping service and the cab sounds great tone wise but there's what appears to be a build flaw that's resulting in what sounds like an air leak between the drivers and the baffle (very noticeable "flutter" on lower notes). I've got comms out to Mark about it so we'll see how it gets resolved. I'll reserve my full review and comments until I've spoken to Marc about the problem...
