Roland Cube 60 Bass Amp, Ext Cab?

[Count Bassie]

Looking at a trade for this early 80s Roland, 60w. The report on those is good for small gigs and rehearsals.
There's is an ext speaker Jack on the back panel, what suitable cab would you use?
Just an inquiry, I've searched online and coming up light so far. Thanks for informative or thoughtful replies!

Is this the model?

Looks like the jack on the back say 8ohms.
So technically any 8ohm speaker in the 60 to 100 watt range would work AFAIK.
Adding the extra 8ohm speaker runs the amp down to 4ohm range, which would put the amp around 120watt at 4ohm range.
Personally I would go for a larger speaker like a 15”. More surface area to move air.

Edit: Another option would be to find another cube that has a good speaker and a bad amp and just use the speaker part of it.
Removing the amp module is easy and so is wiring in a jack to a single 8ohm speaker.

I think it's more likely that an extension cab is required for full power (60W). With only the internal speaker, I would expect 50-70% of rated power on the internal speaker; so between 30W and 42W. From what I have seen, Roland seems to be quite optimistic with their amp power ratings; so actual power could be much lower.

I have no experience with their 80s amps, but ones from a decade ago were very conservatively rated and pushed bigger than the higher rated counterparts from other brands. I own a cube street ex (not a bass amp tho), owned a micro cube bass rx and played the newer cube 60xl. neither of them had an external speaker jack tho.

yeah, I know the sad story with new Katana Bass that uses peak rating to mimic a powerful amp, that's surely sad.
