Anyone used B&C Speaker 320K/C-A ?

Not heared, but when i look at the specs and the graphs it does not look good. They have a very ragged response with dips and peaks over 15dB. The FS is way to high (82Hz).

For that kind of fullrange drivers i would rather go for the Fane 12-250TC (which i'm doing right now). B&C makes great speakers, but this is not one of them.
 
The HF extension is commendable, but the dip/peak combo 1-3kHz is something I'd avoid.

It might be possible to fix it with modifications to the cone(s). If I saw one cheap enough that I didn't mind taking a gamble, I might try it.
