From memory, the 421-8H Series II is the highest power handling of all the 421 units.
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.........................
Not all vegetables make good leaders.
Very interesting. I would like to be there for that comparison and I'm guessing others would as well. I think the 825/828 cabinet would be a good starting point. Too bad we don't live closer together or we could arrange that for this weekend.
Nothing like a great big pair of speakers to make your day.

I think I might be able to pick out a 421, but not because of the LF extension...there are noticeable differences in the upper bass...actually in some ways the 421 may well sound slightly better in that area.
The 421 WAS widely used as a bass guitar unit, Acoustic, Sunn and others bought them OEM. At least early, way more used that way. AFAIK only Altec used them OEM for PA, but then Altec probably sold as may as all those manufacturers put together.
I do not mean to imply the 421 is a bad unit. It isn't. There is also a later 921. I am pretty certain it is a refinement of the 421. Have been told it has slightly less LF, but have never tested a pair.
The 416 will go at least 10 Hz or so lower though. Might be an issue for some. But as bfish says, for 90%, a moot point.
And with subs, honestly the 421 may be a better mid bass. I do not like it as well in horns, at least the truncated A7. I think it would perform MUCH better in say, an 815. Now there is a mid bass system...

With the tendency toward higher crossover points the 421 may come back into favor. But for now they can be had at bargain rates for the performance.

I see the 815 cabinet was available with either driver and the specs available for the day were remarkably similar.

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?
Probably. Retune the boxes using one of the available programs, convert the 808's to 802's and recap the crossovers would do wonders.
Or new boxes from scratch, even better.

Running them active and adding an EQ also works. Doesn't hurt to extend the holes into ports and adding some socks. (aperiodic)
