First, my apologies for lighting this forum a fire this afternoon with all this very specific tweeter talk.
As the subject line suggests, I'm curious if the JBL 053TI and 053TIS are interchangeable from the perspective of installing them into a JBL LSR28P. Does anyone know? Has anyone tried this? Obviously i'm most interested if the dimensions of the tweeter are the same, and if the screw holes will line up??? Does anyone know?
