    Should be no fiber fill below the level of the MW's. You're right - having it down there will reduce bass response.

    Is there a schematic for the older original SDA 2 ? I don't see it. If I were to have someone work on the crossovers They would need that to know the value of the induction coils. A parts list as well. I will have the coils tested before going forward.
