BSC, sloped baffle?

[PeteMcK]

BSC freq for a square box is easy to calculate, but how about for the box attached (top view). I assume baffle step will commence at the freq determined by the box width at front of the driver, but the fall off will only be gradual until the freq determined by the width at the rear of the sloping pieces, where the full step will occur…???

Hi
Depending on the driver and actual baffle angles/dimensions, I think what you said is correct for smaller sizes, But for larger sizes it will be further out a little on the angled side. You could DL the edge program and play with it. Use a 4" and 10" driver to check.
