Question Re: C and R value/ratio on line level crossover filters

Posted by Ian L (A) on November 28, 2005 at 18:02:10

After fooling around with a friend's Behringer for a couple of weeks , it's clear that biamping is the wave of the future ! `,;^)
I've ordered a couple of Marchand XM26 boards and am wondering about parts for it. Phil Marchand usually ships the full kit with 3300pF caps for the frequency filters and you size the R's according to the chosen Crossover Frequency.
Checking out the calulator on the Marchand website, It looks to me like he chose 3300pF as the most convenient value for experimenting with a broad range of crossover frequencies, enabling use of decent loading R values anywhere across the band. My question is. . .

If you know what the crossover point is going to be , would there not be an optimum Value for C and R at that frequency?
thanks in advance!
