Free air resonance?


What is free air resonance and does it make a big difference if one tweeter's free air resonance is high or low? Would 1500 be better than 600 or vice versa? I am thinking of changing my Vifa's which came with my Hales T5's which have a free air resonance of 1500 or so to the Seas Millenium which has a free air resonance of 600.
Any explanation or advice would be greatly appreciated.

That was my intent.

I'm unfamiliar with your level of expertise - which is why
I stated it was not an "amateur's mod".

If you are a seasoned "speaker-mod" expert - then be my guest.

In the original design of the speaker, avoiding resonances is
desired for the reasons Sean, Greg, and Joe... have stated.

However, Tkwolek has a point here.

If you are going to replace drivers with drivers of a different
design - then you effectively have to re-engineer the entire
speaker system. If you are up to that task...

However, the original designer certainly took the resonance
characteristics of the original drivers into consideration
when the speaker was originally designed and made provision
for same.

Substituting drivers into a pre-existing speaker system is
probably an "iffy" proposition - unless you know an awful
lot about speaker design. It's not an "amateur's mod".
