Michael,
Nothing yet. I'm torn between dropping the speaker altogether (no margin in it), doing my own (big learning curve), and ignoring the Seas drivers, which are grossly overpriced. It's all a bit hard.
In the meantime, I'm working on my core business, the power supplies, amp designs, Swift manufacture, and the MC Head Amp.
How about I speak with Ron, and you can call him and chat?
Cheers,
Hugh
