So here they sit, fresh cones, weak magnets. What to do with them?
I can not honestly sell them knowing the magnets are shot. Or may I can list them on eBay cheap with full disclosure? Really don't know what to do with them. Would like to get a little money back out of them, but do not want to cheat the next owner. Right now they're just taking up shelf space.

So both 416-8a(s) have weak magnets according to Bills measurements and can't hold a charge .

Some conjecture ; perhaps some 416s from the LTV era just had less magnet to begin with . That wouldn't be that far fetched IMO .

Remember, this is the same management team that thought it was a brilliant idea ( not ! ) to create the 804/806 by removing alnico ( surplus really ???? ) from the 802 to then foist upon the unsuspecting buying public ( who by & large at the time, had little measurement capacity to understand the consequences ).

- What to do ? DIY forum has a lot of guys in love with the OB concept ( usually using high Qtc drivers ) . Your Qtc figures show your woofers are now closer to that OP standard .
- Market your woofers to them as a compromise solution ( some guys want their cake & the ability to eat it also / ie ; want Altec with its historical low Qtc(s) but then implement them in OBs which require high Qtc ) .
