Just got a nice email from Acoustic Energy:
Hi David
Thanks for getting in touch, I'm sorry to hear about the loose binding post.
You would need to carefully remove the drive unit, the binding post fixing is directly behind. You should be able to access it with a spanner (or if you remove the cable then use a socket) and tighten it this way.
Please let me know if you need any further help.
All the best
Wayne
