Chadwick Modifications used to advertise in the classified sections of audio magazines. He offered an upgrade service for Thorens turntables.
Steven Chadwick Grant died on January 18, 1999 and Chadwick Modifications is no more. Steven had documented none of the features he employed in his Thorens turntables and cartridge modifications. In his prime he could make those things really sing. Sadly, Steven and all of his knowledge are now gone.
We have listed a few dynamic speakers that we think are made by Chadwick. We found no further reference on these speakers.
