Magnepan 1.6 active 24db slop better than stock?

I'm bi- amping my magnepan 1.6's with Rane 22b,s.I have gobs of class A and triode power so that no problem.Do I go from my 22b's(to use gain control for each amps plus crossover for my subs) to my passive crossovers or bypass them and go 100% active Linkworth Riley 24db.If I do go active with 24db slope do I have to change polarity on my quasi tweeters.Can changing polarity(low to quasi)(and if I make a mistake)at any time one way or another hurt the speakers?Any opinions or expertize which way will sound better will be appreciated.

Sounds like a good plan Swordshield. Please report back your findings. That QR tweeter can go WAY lower than the standard passive xover, I think I went as low as 900 Hz with interesting results.

Had the 1.6 and did exactly what you are considering - biamped with 24 db slopes. This was a few years ago and I can't remember the xover frequency but I am guessing it was around 1.5k. It was much more transparent with tighter bass. I played with the phase of the tweeter and I think I preferred normal phase. It's pretty easy to try this yourself. The speaker also becomes much more efficient.
