Re: Are TAD transducers worth the premium costs?

What you are mostly paying for is the sputtered Be diaphragm. This gets you pistonic motion to a higher frequency than the same diaphragm in titanium or aluminum. There is a nice surface velocity scan in a JBL AES preprint that showing the difference between one of their Be 3" domes and a Ti dome. Can you hear this - I don't know.

I would add that all the comments below about tone, etc. are very possibly attributable to non-flat frequency response and proper system / crossover design would correct this. There could also be issues with the horn used, etc. My point is really that to answer this question you need to do the comparison yourself so you know what all the variables are and filter it all through your own hearing mechanism.

I think if it was me, I'd try the JBL Be drivers first (which I am, in fact). They're a bit cheaper, maybe due to using Be foil instead of sputtering. I have the suspicion that their phase plugs are better and take better advantage of the high end of the Be, but all I have for response curves are 2" PWT plots, so it's hard to really tell.
