Yes. You remove the drive unit to access the rear terminal plate. You'll have to pull the sponge wadding about a bit to reach the securing screws. Once the plate is free, if there's enough slack in the wiring, you can either poke it through the back opening to work on or do it from the front. I doubt you'd need to undo the tweeter control panel on the front to gain some slack, but that is also easy, should you need to. If necessary, the wadding can be secured back in place with contact adhesive.
I'd opt for the first terminals shown above: http://www.ebay.co.uk/itm/2x-Amplifi...c=1&rmvSB=true
They are sturdy, fit properly, are of good quality and will accept bare wires and 4mm banana plugs.
This job is well worth doing as the original spring terminals are a real pain!
It is impossible for anything digital to sound analogue, because it isn't analogue!
