There are many other factors, which need to be considered. How about Seas efficiency? If it's different from Vifa, you may change the balance of your speaker. I wouldn't change the drivers of high performance speaker. The maker definitely was matching the units or spec. ordered the units. The crossover was most likely balanced to match the particular drivers.
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.

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".

Like i said in my second post in this thread...... Sean > |
While your point is well taken, Dr., with all due respect, I have upgraded tweeters many times, including this spring. Never with less than terrific results. Replacing my Vifa D27 with the Scan Speak Revelators was a tremendous improvement in air, detail, not having the sound become irritating when the volume goes up, etc. Other than the money, there is not one facet of this changeover that took me a step backwards. But, again, you raise a caveat. |
