REW has the required measurement capabilities but the problem is to be able to play each individual drivers at the same time. Do you have 3 pairs of binding posts at the back? Otherwise it may still be feasible but more complicated. Please report back and we'll see.Is it possible to use measure with REW,
in order to find what the crossover frequencies of a Passive 3-Way speaker are?
I get what your saying. Will attempt tomorrow. Not sure how accurate it will be.You can do this by placing the mic very close to the speaker ie about an inch away and run the sweeps.
It may not be perfect but should allow you to determine the crossover points.
+1The absolute best way to measure would be to disconnect two of the drivers at a time.
Agree that the blue curve should logically be the midrange but you also get a lot of the tweeter’s response in the blue curve since the tweeter is omnidirectional at these frequencies (ka < 2 at 4kHz). This is likely why both curves are parallel in that range, too. All levels being equal, the upper frequency driver will always “leak” more into the lower frequency driver’s measurement than the opposite (since the larger driver starts to “beam” at some frequency). My guess is the crossover is minimal.That said, assuming the blue trace is the midrange, it’s curious and unusual that the midrange and tweeter overlap across a one-octave range between 4-8 kHz.
