Phrased like that it appears you know a lot about crossovers ...

Wayne,

Looks can be deceiving!!! I know a tiny fractrion of all there is to know about crossovers. The chart you posted is great, it illustates my point perfectly. In order to sum flat both the 12 and 24 db per octave slopes should be -6 db at the crossover frequency and the 12 db per octave slope should start to roll off further away from the crossover point that the 24 db per octave slope.

If you were to cheat and adjust the crossover frequency of the 12 db per octave slope in REW until you reached - 6db at the crossover frequency the initial roll off may be correct for the intended crossover frequency.

I hope it doesn't seem like I am nit picking, REW is an awesome tool. I couldn't imagine trying to set up the BFD without it!

Thanks,

Jason
