I have a 70's guitar combo amp which I use with my basses - an FBT Jumbo 100. I bought it thinking it's a 100W unit, especially because it's kind of enormous. Turns out, it's a 10W amp. When I open it, I see it has a 12" speaker.. I'm planning to replace the PSU and amp circuitry in it, so I can get about 30W out of this. However, should I keep the speaker? The text on the speaker doesn't give any hint on what is its power. rating. All I could find online is that it's an old Philips unit, and that it has a nominal impedance of 4 ohm, which I could confirm myself, but no firm info on power.
So the question is: what is the lowest power 12" cabinet speaker's power output? I would be surprised if it were only 10W.

They were rated at 15Watts RMS. Here is some data on them;
Philips part number; 2422 (Denotes finished product) 257 (factory ID) and 51001 (item stock code). Designed for Public Address employment and mid range applications.

Thank you kindly!
Just for clarification: on the 3rd page they list "power handling capacity" at 25W. Is that different from RMS power, in some way? I think it isn't.
RMS does not apply to power, power is just power. So yes, it is supposed to mean 25W unless otherwise specified.
wattage wise there equivalent to a celestion greenback....
interesting that in the spec's they state that the driver is tested/measured unmounted.

Yup, thanks! With 25W I can actually use it. I'll start making plans for a new PSU and power amp. I'll leave the preamp in place - which means, physically the oroginal board will stay in and I'll just add my own power output section. There's plenty of room, there.
