Some numbers are readily available and some are more problematic. The LS3/5A was liscensed to a number of manufacturers, Chartwell, Rogers, Spendor, etc. So numbers are going to be hard to come by, but they are pretty common speakers.
But take the JBL Paragon, for example. A genuine classic. It is documented that the speaker was in production for 27 years. Approximate output was three pairs per month. It is safe to say that total production was in the area of 1000 units.
There are very few pieces of audio gear that were made in really small numbers like this. Certainly the Beveridge electrostatics and Roger Modjeski designed Beveridge preamp fall into the category, as well as The Rappaport AMP1. But Quad ESL57s and most Mac and Marantz consumer audio products were certainly made in much greater numbers.
