I may have asked this years ago. Anyone know anything about the HF1400? I have some in my B&W DM3's and a spare pair. They have bigger magnets than the HF1300, and are used in a BBC speaker, can't remember which.

I'm thinking, the HF1400, with suitable component adjustment, might be better in a BC1 or LS3/6? In the LS3/6 I can easily adjust for tweeter sensitivity with the taps on the autotransformer.
