The plan is to get these drive units sounding the way I want and then building a pair of tapered transmission line cabinets for them. The 12" drivers in my Cheviots are too big for me to build sensible sized TL enclosures for. Hence these 10" drivers. I've got a hankering for some TLs and they have to be Tannoy DC driven.

I can't believe how much difference those little paper cone stickers have made, I expect I could stick them on the reverse side of the cone out of sight and achieve similar effects.
