Mounting two EVM12L in my 4x12.
If anyone here has done that before, tell me what kind of washer do you use between the back of the rim and the baffle?
Contrarily to most speakers the (the older anyway like Black shadow or EOM) EVM12L has a hollow space in the back of the rim which would make it hard to just stick some thin foam like on most front-loaded speakers.
I thought about using some thin strip of hard insulation foam and stick it in the gaps with 1/8" sticking out so it can compress against the baffle and keep it tight, but there might be better stuff out there, so I'm all ears.
Example of the gap I'm talking about, check the rim:
