Fitting Trim on DLS R4

First some test fit shots.. -held on by tape for pictures only.
Not sure how this can be secured maybe some sort of EPOXY?


Now the measurement shots.

From top to bottom

From Back of trim ring to bottom of magnet ( UNDER 50MM )

Same as above but measured from a diff spot ( STILL UNDER 50MM )

( 9/16 ) 14.2mm into the door

From reading this thread - We may have up to 15mm
so this would work. That thread is an E93 which is shallower but same grill.

I dont have a spare door panel to test fit yet. If anyone knows how much room we have inside the grill that would be great.

From the looks of it were under 50mm at the back so we could even shave a little off the front lip and move the speaker back more into the door itself if we needed too.

If people are just looking for another way to make a trim ring by sacrificing your stock speaker speakers this maybe your way, If people are interested in something being made
like this in aluminum and we can secure enough people maybe that can be done as well. Not sure how we would secure the speaker to the adaptor maybe EPOXY?
