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.

Hi Ngjockey,I went to Asylums and all over the web and found nothing on the subject of high slopes and noise.Do you know any other sites or pacific treads at Asylums dealing with noise.I thank all the plus factors outweigh the asymmetric slope but noise and how much?Quite a few people have gone active.I just want to try and get info before taking apart my Magnepans.Have you dealt with this before or heard any systems done active 24db? Chris at Rane nothing but++++ on active 24db.Any help or info appreciated.
Don't have an issue with op-amps but doesn't it make sense. in general, that two in series will be twice as noisy as one? Whether that's noticeable depends on the implementation.
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.

Thanks Grege,I'm going to hook up one channel passive,straight shot right out of my preamp to one amp to passive crossover.No other sub, Magnepans only.Then on the other side I'm going to hook up two way active, Magnepans only no other sub.Back and forth with balance.May the best crossover win.
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.
