no, so they say
I think it's originally 'transformed' from Bessel filter function
this can be handled in passive crossovers
maybe why they say it's really more like 8 or 10db than it is 12db
but will you notice the difference on a graph

but active 12db 'L/R' crossover .... yes could mean trouble
has to be 'compensated', or it could have unintentional peak in xo point

but I clearly remember a very skilled man saying....'what does it matter I don't know anything about BSC when I use measurements'
I shall not tell who said that

Correct.

Now that I have definitively answered the six-year-old question, oszkar, please start your own thread.

The L/R crossover is defined as the cascading of two second order Butterworth filters. By definition, it is 4th order. Period. Now, one can use the idea of spreading the centers and higher Q to any order filter if it works for them. Technically, the crossovers I have built that try and approximate an L/R crossover by incorporating the driver natural rolloff are not L/R crossovers. One does not have the ability to control the Q. They are "inspired by" the gentlemen.
