Hi All,

Something that I've been thinking about for a while with
the design of
speaker crossovers, but don't have the necessary knowledge
to calculate
or figure out, is this:

If you were to take, for example, an 18dB/oct Butterworth
high pass/low
pass crossover for a two way system, could you synthesize
the same
summed electrical response (and therefore the on axis
response) in
terms of amplitude and phase response if you were to lower
the Q of the
high pass section, and raise the Q of the low pass section
from their
standard 0.707, without changing anything else ?

No. While you can play with Q's to get small areas of the
response curve with similar slopes, over the ranges
required, the basic properties of the filters come to the
forefront.
