chockstarfish@hotmail.com Posted January 27, 2002 Share Posted January 27, 2002 I know this is off the "klipsch" subject and not even about home audio but if you could help me in finding the answer it would be alot of help. On tuesday i bought and 1991 Lincoln Continental. and it has these jbl pro speakers and i took the cover off to examine them and found that the "bass" speaker was made out of a material that i was not used to. it was more like a plastic than a paper? it was almost like a flattend out peice of plastic. now i know im not much about this stuff but it didn't seem to be the typical material that speakers are made out of..... and ideas as to what this is? if anyone knows please let me know so that my curiosity doesn't kill me thanx alot Rob ------------------ ------------------------ LaScala (industrial) Main Radio Shack ssm-1200 mixer Carver 400 Amp Pioneer pd-4700 cd player Quote Link to comment Share on other sites More sharing options...

WMcD Posted January 28, 2002 Share Posted January 28, 2002 My guess is that auto manufacturers have turned away from the pulp type material because of the frailty of paper pulp. It doesn't stand up to rain. Looking at some home and industrial bass drivers, plastics and coatings are used for "high tech" eye appeal. And perhaps for stiffness. In the automotive field, though, plastics might well be an environment choice. Gil Quote Link to comment Share on other sites More sharing options...
