Loudspeaker information sought

[Barry]

I have sent Geoff (Walpurgis) a message describing your woofer enclosure project using an EMI elliptical drive unit. Geoff is the only one I know of who has some experience with these units.

He won't be able to test or measure the finished speaker, but he may be able to offer some advice. When the enclosure is finished, post some photos of it here, and try if possible to evaluate the internal dimensions, and hence volume.

I've had problems for about 4 days now, and yesterday couldn't get on at all. Dunno why.

I also had no access for a while yesterday.

Probably over forty years since I built my EMI based speakers. I don't recall that much, but they were around 70 litre reflex boxes.
