I'm with Wayne on this one. I really respect the work Martin King has done and have built his Fostex FE208 Sigma project, with excellent results. One of these days . . . months . . . years . . . I'm going to get some Lowthers DX3 or DX4 drivers and put them in a MK cab. Indeed, if you go to Martin's site you'll see that his latest project is a "virtual" project using Fostex drivers in his Lowther cabinet. So you can build the cabinet now and use them with a pair of Fostexes while you save up for those Lowthers!
