B&C 4 NDS 34 8 Ohms

high sensitivity thanks to a strong magnet.

unfortunately it suffers from a spike in distortion at around 2.3 - 3.3khz caused by what i assume is some kind of breakup hence the 2 khz recomended xover
i ended up crossing it at 2.4khz third order with distortion at an acceptable lvl
you should try to not cross it above 2khz but you need to be careful with your choice of tweeter.

all things considered it is still a good little driver, good sound and high sensitivity is not easy to come by at this size and price range and for that you pay a price
