I have been eyeing this set as well and the ms subs.

However, I plan to use them passive. Im assuming you are active since you have the pioneer deck. How are the passives built regarding quality of components?

You say the titanium dome has sharpness equivalent to a soft dome? Since you were coming from a pointsource kef, where did you install the tweeters ?

Have you considered trying the passives just to see hear how it sounds?
