Default Revision to JBL C.N. 270637 for BSC

Some help here please.

http://www.jblproservice.com/pdf/Sou...ries/I710P.pdf

I'm building them from scratch - different shaped box (same volume). BUT, they will be used for surrounds and installed 'in-wall' with the speaker baffle exactly flush with the wall.

What components on the crossover network should I try swapping/experimenting with to get rid of or reduce the BSC.?

I can do measurements in the final analysis but need some idea around the component(s) I should look at before I construct the crossover. This will help me make allowances for swapping in/out before the final board make up is settled on and soldered.

Appreciate your help....

Most likely if this design has BSC it has been done with an oversize bass in inductor in combination with a capacitor that doesnt turn over till the crossover region.
