Advent Pearl bracket mount speakers

[hpp3]

Hey folks,
I just picked up a pair of Advent Pearls that are missing the bracket mounts and the face covers.
Found them at a thrift shop for 8 bucks apiece, so I didnt complain much.
They don't need the brackets, and some hardware cloth and tin snips will get me some decent covers, and I can say they're the best sounding speakers I've ever owned (not saying much, I'm not a very rich man).

What I really miss is the specs for these particular models.
There is nothing printed on the back, like the usual ohms and watts, but there's not even a model number or anything; just 'Advent Pearl' and some 'Tested by' and 'Inspected by' initials.
The speakers inside don't have anything but manufacturer markings printed on them, and my multimeter tells me 5 ohms.
There's a crossover inside, so that may skew the mm a bit, but what I'm after is hard info.

Anybody have any specs on these, like dB/W, power handling, frequency response, etc.?
There is absolutely nothing on the 'net about these things, which is rather unusual.

You might have a more recent model of an Advent 5" mini-speaker.
Here some reading of the bigger 9" vintage brother.

Your Advents are from the Jensen period and have nothing to do with the "real" Advents, as in "smaller". They are good, though the foam surrounds are most likely shot. Trapezoidal enclosures! Audax tweeters! Enjoy!

Yes, these are the 5.25" woofer models, and the foams look almost brand new.
Lots of replacement kits going around, so maybe they've been done already.
I kinda figured they were Jensen period, but either way some good info on how they handle would be nice.
