Doing a lot of reading on this forum about Altec model 19's and i was reading a thread that was mentioning BMS drivers to replace the 802 G in model 19's because of their high frequency extension. So i was reading about the BMS drivers they seem to spec out very good it was interesting to read they lighten the diaphragm by flattening it out instead of making it a dome this reduced the surface area and therefore made it lighter and they it made out of polyester. The first time i heard a diaphragm that was not made of metal was in a 15" G 610 Jensen triaxle the tweeter on that speaker has a linen diaphgram and i remember it to be one of the best tweeters i had ever heard.
So have any model 19 owners in the forum used this driver? and if so how do you like it?
