There were various speakers back in the 1950's and early 60's that
deliberately used 'flimsy' panels to fiddle about with the resonances,

will re-invent it in due course as a major new advance. :-)

Wasn't the first to do this accurately the BC1? On the principle that
you can't make a perfectly resonance free cabinet speaker, so use CAD to
assess those resonances and make them work for you?

I'm not sure when the BC1 was designed/released. However my recollection is
of a speaker called something like the 'CQ' that appeared around 1960. This
was well before the days of 'CAD' being more than a role for Terry Thomas.
:-) I'll need to dig out the relevant copy of HFN when I go to where I am
keeping them to check. I'll pass on the 'CQ' being 'accurate'. ;-

There was also a speaker similar in principle to the 'isobarik'.

Maybe I should do some pages on 'old weird speakers' as people seem to have
forgotten a lot of these. Sometimes the wheels are re-invented, sometimes
forgotten.

Slainte,

Jim
