I denna tråd på DIYaudioforums hittar du litegrann om Alpairelementen. Främst avses alpair 10, men det gäller nog för den mindre med.
"While the Alpair 10 might initially be considered as a clone of the Jordan JX92S driver, several differences can be discerned. First, the composite frame of the Alpair is larger and thicker than the cast metal frame of the Jordan. Next the basket of the Alpair is more massive than the Jordan driver so my past experience with a cracked frame with a Jordan driver will not be repeated with the A10. The Alpair 10 cone is attached via a concave surround versus the standard top mounted convex surround on the JX92S. Bottom line is that the two drivers are similar in their spun aluminum cones but their construction is substantially different."
