Lanzar, they any good

[p fandango]

i've been working on Bonny's stereo quite a bit & been thinking of using an active crossover. I used to have a brilliant Kenwood KEC-600 but sold it when BT went light-weight. The Lanzar OptiX 10 crossover seems to be popping up alot in Google, but are they any good?
