The usual tests are on the main page and in the tidbits section, but more recent results that haven't been posted in the main section yet are here:

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.)

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.
