Way to Go Zaph!!

That little RS52 looks pretty sweet..

The HiVi makes me wonder what a modified rear chamber could do for it..

I read his new tests over the weekend - I am very impressed with the new layout he uses and the rating system - very informative and user-friendly.

I am even more convinced than ever that he has one of the best DIY sites out there, and I hope he continues this type of service to the community for years to come. I have made virtually all of my driver buying decisions based on his tests.

Another first-rate job John - thanks a million and keep up the good work!

P.S. - any idea when the RS90 will be out? Looks like it has some decent potential.

I am interested with the what the faraday ring does to the driver. Listening to two wide range drivers with faraday ring it seems the sound is a bit soothed. Violins don't sound that real. It does seem to reduce distortion in the lower frequency range and the bass is notibly cleaner.

Another interesting thing about drivers with faraday rings is that the impedance curve seems flatter, and the impedance phase seems close to zero ant the higer frequencies.

Unvaluable work for others, mr. Zaph

I think you mean "invaluable" Methman.

I second that. Great work.

From driver sweep distortion tests to a loudspeaker there is a long way though.
Valuable for knowing the real specs instead of those claimed nontheless.

The test results posted by John on his site are very useful in several ways , and I thank him for sharing this information with us.

I would phrase that as :-
"valuable for knowing the real specs of a production sample instead of those claimed nontheless"

Even from the quality- conscious manufacturers there have been significant variations in some parameters from one production-run , or batch , than another , and particually when the company relies on other suppliers for production-ready materials . For the lesser-quality brands , there has been significant variations between samples all from the same batch , often owing to less than meticulous assembly of the lesser visible and hidden components . Despite this , knowing a sample's measured data provides a good start point for further evaluation .

Well yes of course, but these tests provide excellent starting points! And Zaph has some great designs too.
