I spoke to Ed about this last year when Peerless discontinued the woofer/tweeter.
He seemed to leave the door open to a new EFE DIY kit, though with the thousands of designs available now, I wouldn't blame for not bothering.
I think he scans the DIY forum regularly, so perhaps moving this thread there or putting in a request would draw his attention?

I built around 20 of those things. I have 7 of my own (though I finally made an MTM derivative for a center channel) I still use in my home theater. Since they were first made, a lot of new drivers and kits have hit the market and the bar has risen considerably as the DIY speaker market experienced a boom. That said, the ar.com is still not out of place beside many of them.
