Trying to do a similar frequency distribution between drivers as in a full size cinema and have been toying with the idea of a 12" prosound driver for 80-500hz and use a mid size full range above. In a true cinema, above 12k is usually rolled of a little, sometimes deliberately but...
Forgive me if it's covered somplace, but I was wondering if REW will place filters above what looks like a 500hz limit? I know the BFD will make them higher... and that for sub use, you never want to go that high.
I was thinking more in regards to mains speaker rolling off and flattening.
