Interdyn speakers were made in Melbourne by Acousticoncepts in
Braeside by John Woodhead. They were made by Acousticoncepts for
International Dynamics and soud through Encel HiFi. Most models of
the Interdyn speakers use SEAS drivers and were designed locally.
The P33 was an earlier model which used a 10 inch bass driver, a mid
and a metal domed tweeter. The bass driver still sells today at over
$150 each. There was a two way version of this model, a pair of
which recently sold on ebay for over $120 and they were in very
average condition. The P33 had a nicely made real wood vereer
cabinet which would come up very nice with sanding and a respray.
The P33 would still be one of the more sought after Interdyn speakers
along with the later BT2's. Acousticoncepts still have design
records of most if not all of the Interdyn range of speakers and is
still the importer of SEAS drivers.
