Altec 421 woofer

[artlab]

Replace the shiny dustcap with a vented paper one, slap a piece of duct tape over the vent on the back of the magnet, and 95% of the population(audiophools included) won't have a clue they're not listening to a genuine alnico 416 or 515. In fact, i'd be very surprised if many of the altec experts could pick the 421 in a blind test without the aluminum dome in place.

Just my .02.........................

I got offered a pair of 1233 PA speakers cheap. They have 421-8 LF's with 811 horns and 808 drivers. The cabinet volume is about 10.25 cubic ft. Is it possible to do a DIY conversion and have some home stereo speakers that would be acceptable to my relatively untrained ear?
