Here’s a little snippet I’ve just remembered from way back when . . .

Q: Did you know the reason for Raymond Cooke (KEF’s founder) designing the B139 the way he did?
A: To avoid paying Purchase Tax on the finished speaker!

At the time, Purchase Tax was exempt on all drive units over 12” diameter or over 12” on their major axis. You see, the B139 is effectively only a 10" diameter unit, but squashing it into the now familiar shape makes the major axis in excess of 12" and hence exempt. Also tax free were any enclosures having 3 drive units or more – hence the ‘trend’ at the time for supertweeters.

Anyone want a mint pair of Coles Supertweeters?

If they are K's yes, as for G's I've at least a dozen, so no thanks Very Happy . Why? Well an ill-mannered switch on thump from an amplifier will kill them in about a week.

Wasn't the other fiddle to do with "kits" specifically Heathkit, where the home builder's act of screwing things together provided some form of exemption?

Absolutely, all kits were tax free too. In the automotive field, even Citroen shipped over crates of 2CV parts for a while in the 1960's for home assembly - £199 I recall.

Many an electronics novice warmed up their soldering iron for the first time on a Heathkit - the firm is still about today, although not making kits.
