Thanks, FL!
Okay.
So my stock is 8 ohms and so is the Celestino in the link so it would be an appropriate (though expensive) fix and I theoretically should not lose any volume.
Where could I find the specs on the stock speaker such as weight?
It’s not in the BA manual.
By the way, everybody:
@bhendrix
The audition went great!
It was really one of those things that was like we had played together before!
They offered me the position and gave me the option to think about it.
I accepted on the spot!
AH, a hearty congrats for making the band! Oh, the fun you’ll have...make sure to drop us an update in between gigs.
No deep specs on the BA speaker, but you might find an appreciation thread where they take things like that apart. As far as volume goes with each speaker, it’ll depend on each speaker’s SPL (sound pressure level) rating. The Celestion maybe more efficient and thus get you more volume. On the other hand, it could be less efficient and not play as loud.
I can tell you this without hearing them, they’re gonna sound very different from each other. The Celestion brand has a distinct sound to them and I haven’t a clue if you’d like it in an American Ampeg. If it’s a cheap replacement, go ahead and experiment (my fave thing to do with my $), but if it’s gonna cost you some coin, I wouldn’t do it if I already like the tone. Buyer beware!
Great news on the board that was fun to read. My news: I bought a new Furman power strip tonight for me low-budget studio. That’s it. I’ll be putting it together over break which will be happening in exactly two weeks!
Continue on, CC crew!

At the very least, you'll wind up with an extra speaker in case one blows.
