Free air resonance?

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.

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.

Hello Dr,
Would you then reccommend that I leave well enough alone? I should note that an amp designer (the one who designed my amp in fact) replaced his Hales T5's Vifa's with the same Millenium tweeter that I am going to get. He did remove the .33 ohm resistance from the crossovers tweeter section however but he was extremely pleased with the results. What I am saying is that I am not doing this blind but following the experience of a proffesional who had success with exactly the same upgrade. The only difference is that I redid my crossovers(with success) and he did not upgrade the crossovers. I did keep the Hales T5's crossover's design and kept all the origional values.

Mitch, I am not sure what the doctor has to say, but I emphatically feel that with all of the money you have invested in upgrading the crossover and wiring, considering the pretty high level of the Hales woofer and cabinetry, the weak point of your speakers at this point is clearly, Clearly, CLEARLY the tweeter.

Tweeters are the drivers that have possibly come the furthest in the past 10 years. And, they sure had far to come. At that time, the Dynaudio Esotar, Esotec, Morel MDT33, and ScanSpeak Revelator were the best you could get. Outside of the Esotec and Morel, none could really be considered reasonably priced, but all were MUCH (orders of magnitude) more expensive than the everyday Vifa/Seas/whatever metal domes in most speakers.

In your case, unfortunately, you were on the cusp of the arrival of the better affordable tweeters, but fell on the bad side of the fence.

JUST UPGRADE THE DAMN TWEETER!!!!!!!!!!!!!!!!!!!!!!!!!!!!! You'll love it! But, as I also told you before, please give it 50 hours before you really judge it.

I think you should go for it! Those tweets will surely out perform the stock tweets in your speakers. There's just some things charts and graphs cannot explain. If you use those things the good lord gave you on both sides of your head..I think you will be alright!

Or put the other way JUST UPGRADE THE DAMN THINGS!!! LOL

Good Listening!
