'Exchange' re-conditioned parts were once very common. If the old part
wasn't suitable for re-conditioning a surcharge was made.

Indeed they were, particularly with car-parts. Almost all the major
mechanical parts: engines, gearboxes, back axles and larger electrical
parts: dynamos, starter motors etc. were available as reconditioned items
with the old part being returned to the factory as part of the deal. Or you
could buy a brand new part, without having to return your old one, at a much
higher price.

It could be the makers of these speakers are very short of units suitable
for re-conditioning, so only offer this service where yours is.

Sounds like the retailer made a mistake.

Indeed. There's nothing wrong with exchange units, so long as everyone knows
what the deal is. The error here is that the dealer promised to return the
old driver to Rob, then failed to live up to that promise. So he's in breach
of his contract.
