Was looking at some info today on the KEF B110, and the KEF blurb says
it should be front mounted on the baffle, recessed so the chassis is
flush with the front of the baffle. Yet on perhaps its most famous
application, the LS 3/5a, it's mounted to the back of the baffle.

Maybe because it's intended to go on a shelf above the desk in an
outside-broadcast van
so moving the B110 back 3/4" keeps it in phase with the T27 at the
crossover frequency.

Thing is the Kef blurb says mounting it behind the baffle introduces
unwanted colorations at the mid band.

How about this then?

That's the 5/8. Interesting that the later units dispensed with the square
slot over the bass unit.

The other thing that's interesting about that article is that they say the
requirement was to not use a midrange because of the cost and complexity
of the crossover, which is very true, especially with its predecessor the
5/5 which was passive. But then they used an active design.
