Passive Crossover Build Help

"The question is whether we can make a crossover at all without measurements - and the answer is NO.
It cannot be done, and crossovers cannot be calculated."

Without measurements it's like working in the dark.
At the crossover point you need to see how the drivers interact to get the phase and FR good.
Here are 4 measurements of the mid and tweeter of my latest project, the yellow graph is with the tweeter wiring inverted to check the phase.
Impossible to do this without measurements.

@danny that looks nice, what did you measure that with?

 

[danny_66]

I measured those with the following setup:
- calibrated Monacor ECM-40 microphone
- Behringer UMC204HD AD/DA
- inroom measurement at 1.10m distance, height between mid and ribbon driver
- REW with frequency dependent window of 8 cycles, no smoothing

Very cool!

Thx, in a few weeks the crossover will be finalized and I'll create a new thread with some info and pics.

Yeah please do. My DSP is coming soon so I plan to get some measurements soon.
