Hi, if nothing else helps, follow VituixCAD REW measurement manual very closely and you are fine. In short
- measure each driver 0-axis maintaining mic distance from baffle plane (any common plane, baffle makes most sense) using timing reference
- process all data with same windowing
- leave z = 0 in vituixCAD drivers. Use y coordinate to move driver up / down where it is in reality, relative to intended listening axis (height).
An impulse is dependent on phase. Phase will not lead you to a clean impulse with an arbitrary response.take an impulse measurement at the frequencies of where I plan to cross them,
The varied baffle arrangement won't be without it's own effect..then I can mechanically align them
This is how I know it, even for the simpler method for far-field measurements, in which all drivers are measured from one axis - e.g. that of the tweeter. All the time information that VituixCAD or similar programs needs for simulation is contained in the measurements if a time reference (electrical or acoustic) is used. Changes to the Z values are then even harmful.leave z = 0 in vituixCAD drivers. Use y coordinate to move driver up / down where it is in reality, relative to intended listening axis (height).
To be honest, I don't really understand the intention of the question. Should the acoustic offset of the drivers be corrected mechanically? I would prefer a pure phase adjustment, because steps and edges on the baffle are not exactly advantageous from an acoustic point of view.
Or you could develop an active crossover and then adjust the offset using delay.
