I have thought of trying the nd13 just never got around to it. Then I remember seeing all the good words about the ND20FB-4 and I start looking into that. The back flange to front distance is 12mm. I figure you could still use 3/4" material by cutting a recess in the back of the panel to flush the front of the little waveguide.

I have a pair of those SD215A-88 drivers I'll sell. They are lightly used but never abused. I'd take $20 each plus shipping.
That's actually $0.02 more expensive than normally 🤔
Yeah, I won't be surprised when they get back in stock they will have "new pricing"
Truth.
