One thing that seems to be a bit misleading is "[i]2 parallel speaker outputs - to use with 2x 8 ohms bass cabinets or 1x 4 ohms bass cabinet[/i]". I believe this would only be the case if you are to disconnect the internal speaker (which is probably 8Ω) as I don't think the amp will run at 2Ω. So when you are adding a cab, do check in the manual what it will take to save overheating.

XGSJX - Wow, bit too techy for me! When I spoke to Ashdown they did say that I could add a cab but I have absolutely idea about the other stuff you've added.

Misleading indeed. My guess is that that text comes from the description of the separate head.
With these combos however, there's no worrying. They work just as separates.
The internal 8Ω speaker is not internally connected, but just connected to one of the two sockets on the back of the amp. Normally one would just plug one extra 8Ω cab into the other socket, and run at 4Ω that way.
Deb, if you do decide to add a cab, just make sure it's rated 8Ω. Ashdown build both 4Ω and 8Ω, and they are clearly marked as such.
best,
