Mon Graci John!

(What "caught my eye": -that Tangband mid-dome seems interesting (1st order on the upper end), as does the Be Usher tweeter (though with some consistency issues). I find it also interesting that the Visaton Al driver has lower non-linear distortion than the Dayton reference sub driver and even a "hair" less than the Scan Speak sub.)

Nice.

Zaph's site is an incredible resource.

Thanks!

Yeah. Someone is going to have to take the helm if he stops testing drivers!

The low harmonic distortion of Scanspeak 22W8851, all the way to mid-high frequency, really surprise me. I originally though it was only a long throw mini sub... No wonder Wilson Audio could use it in 2way.

What caught my eye:

Usher 8137A: Good competition for Peerless 830884, however with slightly higher HD and lower sensitivity.

Visation AL200: Excellent distortion results considering the impedance plot.

Aurum Cantus AC200 MKII: I really expected more from this driver. HD is a bit out of control.

Vifa BC18SG49-08: Excellent overall considering the $13 price tag.

Seas U16RCY/P: Would be an absolutely excellent driver if it weren't for the big bump in 2nd harmonic between 1kHz and 1.5kHz. Beautiful looking driver.

Fountek FR88-EX: Excellent driver, could be used in tweeter-less systems. I'd imagine using this driver with an 8" or 10" driver for bass duty.

Tang Band 75-1558SE: Extremely good midrange, however visually a bit ugly IMO.
