“Their best speakers are still the A series speakers they did back in the day. Those had a super wide baffle, had to be placed in close proximity to the wall. Had paper coned mids and low end. And a seas tweeter...”
I read a review of the a400 in stereo review and it claimed that for the a400, it was the first BA speaker to get an in-house made tweeter.
We’re they wrong in saying that?
IIRC, yes, I think that the A400 was the first Boston product to get the CFT type tweeter, built in-house at Boston. It then was used in the Series 2 version of most of the A-series products, and in many models after that until the late 1980s/early 1990s, when they started developing the AMD (later VR-HO and such) tweeters.
