what part of "minimum recommended crossover frequency 2000Hz./12dB octave" is unclear?
I would imagine results at 950 Hz. WOULD suck. This driver has a huge z peak at 2 kHz., and a 4 dB rise from 2 kHz. to 4 or 5kHz. shown on the PE site's spec sheet. Looked decent at first glance for use in a 3 way system, although I did not look closely at the upper end response. Not sure what advantage they would have over the venerable psd-2002 in this price range:) Sam8 ohm, 3rd order HP, the online calculator showed 14uF series input cap, 1.0 mH shunt inductor, and 42uF series output cap to the lpad/driver for a desired Fc of 950Hz, btw.
