I'm working on a 3 way WWMT, (2x10", 1x7", 1.25" sealed monopole) but encountering some challenges with the W-M crossover.
This is a dual woofer bin at the bottom of a sealed 2 way (think Wilson Watt-Puppy type arrangement)
Can anyone give me some guidance or refer me to some guidelines about to crossover in that critical 100-400Hz region properly?
So far, what i've been done is measure the woofers nearfield (mic distance- 1/2" from centre of cone). With the woofers in parallel I will assume +6dB gain in sensitivity. This give me reliable measurements up to approximately 500Hz. Then I measure the midrange/tweeter farfield, at approximately 2', which incorporates the effects of the baffle. In my room, the gate is long enough to allow measurements to be usable down to about 300Hz. What I'm stuck with now is how to use the nearfield woofer measurements with the farfield measurement of the midrange.
Am I going about this the right way, or have I gone off on a tangent?
