I would agree.
However, I think the "70's/80's" bit is key - i.e. an era when 'speakers were speakers', and not some of the pish purporting to be speakers that are made these days....
Hey, even Briks and Kans were made during that era!
Perhaps Colin is referring to post-1980s Castles? If so, I can see where he's coming from - they're not the same company now :)
