I think @MrBoat has used some of the ebay PCBs on his work.\n\n\nYes. I got a set from ebay for the C-note speakers. Also, when I built the fusion-12, diysoundgroup had not only the pcb, but offered to build it for a ridiculously small fee, so I splurged there too. I really dislike the perfboard, of all the possible alternatives. \n\nI dunno, I reckon if I built the drivers from scratch, and everything about it was my own design, I might have kept it all 'self' made. I build a lot of things as a day job. After awhile, just knowing you can do it is enough.\n\nI am currently sitting on a Paul Carmody Speedster kit. It has the mdf xover boards. I may saturate them with epoxy to plasticize them enough to drill halfway decently, and so that they look a bit more like I cared, at least.
