Ampeg 120W with an 18'' cabinet combo

[mouthmw]

Anyone have any experience with these?
Ignore the 2x12 box below it.





It has an ElectroVoice 18'' speaker installed, and a twitter.
It's solid state 120W.
How good are these?
Loud, powerful?

I can't find any info on these, not even on discontinued Ampeg models page.
18'' doesn't seem to be popular anymore.
I'm probably better off getting a new amp for my 810 Ampeg cab.

Apparently it's an Ampeg B115.
I feel those would be underpowered in a hard rock setting.
