Having listened to a pair of KEF 104aBs in a junk shop recently,
which use the B200 and a BD139 passive radiator in a ~40l box,
I wonder why I've never heard of anyone using a B139 and a BD139
instead of a transmission line or reflex enclosure.
Has anyone seen such a design?

Believe me, in TL speakers a single B139 is more than enough - they
will rattle windows at 10 paces!

Where was the junk shop - I'd buy the 104's if the price was right!

Kings Road Bazaar, St Leonards.
They would have to be really cheap as they were really tatty,
and it's pushing things to cross over a B200 at 3kHz.
