Regarding a forum topic (Dutch sorry for those from elsewhere)   Leave a comment

First a link to the topic .

Topic

So this is the response @ the processor fictional (generator bank out of RBV2-9) .

proc.rsp bp hp filters

The response @ the processor fictional with delay (generator bank out of RBV2-9) .

proc.rsp bp hp filters small delay

The response @ the processor fictional with delay and polarity inverted (generator bank out of RBV2-9) .

proc.rsp bp hp filters small delay high pol inv

The response @ the processor fictional (generator bank out of RBV2-9) shows a dip @ the x-over point . The polarity inversion might be needed because of the relative polarity of the high driver compared to the low driver . All depends of the real live situation so it’s a measurement thing .

Blue trace = 3rd order BTW. high-pass @100Hz 3rd order low-pass @ 1K6

red trace = 4rt order LR High-pass @1K6

Black = sum of blue and red trace . All depends on the real world situation so it needs to be measured to get a clear view of this set-up .

Screenshot of a idea from somebody on that forum . Look at the delay settings ! This is a virtual world so i can give delay negative values in order to get a flat phase response @ the X-over zone . The phase trace starts to go up further up the frequency scale witch you can correct with 2nd order all-pass filters .

Houdt er rekening mee dit is op processor outputs niet op acoustische respons van het systeem en het is een simulatie not the real world .
