I heard that the tweeters are fragile and can be damaged if a lower power than needed amp is driven into amp clipping with them.
There do seem to be exceptions coming back to market, albeit not sealed:

I've never heard nor seen either one of these in person.
Just for fun. Some 25+ years ago, I heard the 801s at Danish Radio's studios, and at Radio France and thought the 801s were the best sound I'd ever heard. However, I was also wedded to the concept of active 'speakers, so when I fancied a project, thought I'd look for some early sealed-box 801s, before they went to vented bass, and make them active. Very enjoyable project and have no desire to change them now.That looks amazing.
Was the crossover degraded and thus the reason to move to DSP, or was it just for fun?
I used ARTA and REW to derive the pseudo-anechoic on axis response, then equalised it flat to +-1dB above 200Hz with a Behringer DEQ2496, and left the bass to take care of itself, as the in-room response was fine.The B&W's looking great was thinking to buy a pair here in holland. Did you measur them using room correction?.

I've never understand why those big horizontal JBLs have so many ports / holes....what's going on there?
Sometimes I read about old, big speakers, especially horn designs, using Alnico magnets.
Some advocates seem to believe they're superior to anything being currently made (unless it also uses Alnico).
Is there any truth to that?
I thought neodymium was the top tier of magnets used in drivers these days....

One advantage of AlNiCo is that it can be easily cast into shape.
I second Yamaha NS1000s, especially when triamped with active crossovers!
I did that with my B&W 801f loudspeakers. Bought a pair of fairly scruffy ones, but they were complete, working, and with grilles and hoods. Took out the passive crossover and replaced it with a DSP crossover and equaliser. Once working properly, had the cabinets reveneered by a local furniture restorer. Definitely keepers, and at a total cost of around £2250 including the reveneering, less than I could buy anything comparable, even used.

Yes, the first 801 Model 80 and the "Mk2" model called the 801f (f for Fibrecrete, which was a lightweight concrete the midrange head was made of) were sealed box bass. They then had the "Mk3" called 801M, which had the matrix construction bass unit which was vented. All subsequent versions of the 801 were vented.Am I reading that right...there was a sealed-bass 801?
"Alnico is commonly thought to produce the most “Vintage” tone and has a reputation for sounding compressed."
Huh....
I tend to think of "driver compression" (not compression drivers) as a bad thing, and representing either thermal overload or loss of linearity in the driver material.
I didn't think a different magnet type could do that?
