Can I use any ten inch speaker to replace the ones I blew out on my Acoustic B810?

I would look into buying new ones directly from Acoustic if you want a cab with matching drivers.

Of bigger concern is whether or not you'll just blow out more drivers once you replace them. What did you do that wiped out part of an 810?

No, You'll need bass guitar drivers that are a match to the cab. If I am not mistaken they are a 32 ohm 10" driver, kinda like an Ampeg 810E. The only thing is that the Acoustic 810 is a bit smaller cab, changing way that a standard replacement driver that works great in the Ampeg is gonna sound in it.

Might look at the Eminence B810, 32 Ohm.
Eminence Legend B810 10" Bass Guitar Driver 32 Ohm 290-468

These are also very popular replacements, for vintage Ampeg square back 810's but wouldn't be My first choice as they were originally designed as guitar speakers.
Jensen MOD Series speakers - Jensen MOD10-50 10" speaker model is great in 4 x 10 speaker cabinets. 4 ohm version works great in Ham Radios.

(IMO) I wouldn't spend too much money replace'n the speakers in the Acoustic cab. You'd probably be better off for the buck's You'll spend to find a used Ampeg 810E, as they can usually be found on Craigslist and the like for under $500.

If it's divided into separate chambers inside like the svt you could use different speakers replaced as a pair in the chamber that has the dead one. Can add the eminence alpha10 to those already mentioned as a more affordable alternative. I wouldn't be dumping too much money into that cab.

Well, nevermind. If it uses 32 ohmers forget the alpha.

I played a show at a reputable venue, but the sound guy seemed like he was new at the job. I tried playing straight just into the mic but He INSISTED on plugging directly into my head. Speakers blew halfway thru the set. As he was unplugging when we finished he pointed out that it was "his bad." Amateur. Idk exactly what happened and after I had it looked at my guy could only figure out I blew em and need them replaced

Wait, How did the sound guy blow your speakers? Did you let him set your volume?

I was also playing on an old acoustic 140 head, which has two input and one booster output. I figure it was just some gimmick because I had never heard of a "booster output" jack. Its a year old cab and I've never had any problems with it until he plugged something in there.

I have an old Acoustic amp with the "booster" jack. The booster out is an early primitive form of the line out, apparently it was intended for driving another power amp. The signal is tapped right off the speaker output, but reduced in level by a resistor. It should work as direct out, I'd run it through a direct box just for ground isolation purposes, but it should work. I presume that's what the sound guy did, used it as a direct out.

I don't see how connecting anything to the booster output could cause your speakers to blow. Sounds like an unfortunate coincidence to me.
