Pair 10 inch Altec Lansing 406 8c Woofer Speakers Vintage 3 inch Voice Coil | eBay

I have yet to hear or test out one of these drivers, but from the specs that I've been able to find, it looks like these would be a pretty good deal at the minimum bid.
I compare them to the AC 250 although the AC goes a bit higher and of course has way more power handling.

I would bet with that big motor and 3" VC, the 406-8C is a pretty impressive smallish driver. Anyone here have/heard one?
