I did a quick search for specs, and found this. I also found a comment from Bill, on TB, that this driver is a better driver than a Delta, for bass guitar. And, to add, an inexpensive way to get in the game.

I don't recall anyone saying they tried them in the O10. Actually, it's been a while since anyone said they used them for anything. The specs don't seem too bad, but there is no chart. You could try them and if they suck you won't be out much cash.

Product Details:
10" Professional Woofer
Perfect for musical instrument, PA and sound reinforcement use. This driver exhibits characteristics typical of drivers at over twice the price. It is an ideal upgrade for the Eminence Alpha Series, and a drop in replacement for the Carvin PS10.
