Jabberwock,
The lenses I described are thin pieces of metal or plastic that disperse the mid frequencies more than the highs (at least that is my theory), The ones I have came from pair of Sansui SP-9X something or other that I bought while overseas in the Navy back in the 70's and 80's, They are plastic but I think they do help tame the bright peizo sound some. Maybe someone on the forum here can find old JBL speaker system with the lenses and post link, I have sore throut and sinus problems today, so somewhat braindead.
Regards, Ron
