Extra Info:

These drivers are very high quality low-distortion mid/woofers that have very high sensitivity and a smooth frequency response that allows them to be used successfully in a high quality 2 way design. They are designed and manufactured in Scandinavia from woven glass-fibre and have a high quality voice coil and motor system.

Think of them as perhaps the successor to the P17WJ poly conde from Vifa. Easy to design with but in this case without the tubby bass (Sorry, I did design with the P17's and that was my experience!)
The speakers have been used in designs by some very respected speaker designers to good effect - http://www.troelsgravesen.dk/DiscoveryW18.htm

Points to note - the speaker has a very good sensitivity at about 93db @ 2.84 volts. They can go down to -3db @ 45hz in an 18 litre box (would be actually lower in room).

I have not done Klippel testing on these speakers but MarkK tested them and thought their performance reflected that of an under-hung VC rather than a conventional design. http://www.zaphaudio.com/blog.html
A good combination of solid bass and good efficiency with good power handling. Would also be good for car applications.

I got these for a project that didn't take off. I am selling them at a loss as they are new - never used.
