external speaker options

[burntumbers]

I have a rare amp that I know very little about, it has a jack for an external speaker, just curious on what my options are.

the amp is an Ibanez IBZ 60 TE

all I know is that it's from the 1980s, MIJ, tube amp with a 12inch 8ohm speaker. it's a copy of some Mesa Boogie amp, with a built in 6band EQ

so for the EX.SP. I'm looking for 1x12 or 2x12...maybe 2x10


I'm a newb at amps, be gentle.

Does the external speaker jack have anything written under it, such as an impedance rating?
