any speakers using all Scanspeak Classic drivers?

Actually, I believe the Lynbrooks use Seas drivers, not Scanspeak.

@thecarpathian  is right, the Linbrook used Seas drivers. Tyler's newer Highland series use all Scanspeak, but they are Revelator series. The older Meadowlark Shearwater, while only a 2 way used Scanspeak classic series for woofer and tweeter. The Meadowlark Blue Heron 2 used Scanspeak classic series woofers and revelator series mid range and tweeters.

The old YG Anat, although the woofer is partially a revelator is my understanding

i think some proac use these althougj most proac use seas and scanspeak
