After seeing a stock speaker ( L7 cause its what I had on hand ) It had a stepped lip that measured 8mm ( 5/16 ) Then there was a rubber lip after that. HMMM ..

My brain started spinning and I started to think, what If I gut this stock speaker as a template for an adaptor and see what we can do...

And we begin : Below is some pics and measurements from the hollowed out bracket trimmed off the speaker.









Details =
  • L7 Driver w/ rubber lip = 1/2 inch ( 12.7mm )
  • Raised lip without rubber lip = 5/16 ( 8mm )

The rubber lip is removed when the speaker is gutted so we are left with a lip of 12.7mm.
