When I worked with the home audio group (Advent and AR) developing speakers, they would get sample speakers from our German sister company that were already in production. However, we had to change the crossover every time because the sample speakers had the "European sound", which in contrast to the West coast sound, was too much treble and bass shy. "Sound" is definitely regional.
I bought two JBL D-130 drivers awhile back and re-coned them. They are close spec wise to the originals. I built a ported enclosure with mid-range horn and horn tweeter (and a custom home-made cross-over) basically emulating the JBL 4331 monitors. The one speaker sounds awesome. It is like a Cornwall, but the bass is so much more articulate due to the D-130 woofer (with it's 4 inch voice coil and super strong magnetic field).
The classic JBL drivers were truly exceptional. You don't see too much engineering like that nowadays.
