Effects of Acoustic Center Position in Subwoofers

[Zero D]

This looks like one to watch out for. Should be interesting

As explained by J.Vanderkooy [1] the acoustic center of a direct radiating subwoofer unit is placed ahead respect to the driver membrane, at a distance depending on driver and cabinet dimensions. This has effects on acoustic simulations and it deserves some attention to avoid errors. Measurements are shown which confirm acoustic center position theoretical calculation and a discussion is made about its effect on the definition of models for accurate simulations.

I placed it in here, but it applies to ALL speakers

Interesting, but I'm not sure this matters to my process.

Using interferometry, the result is always the effective acoustic distances. Perhaps this applies to those who build 3D models in advance?

Best,
