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.

Yes I would bypass the crossover's completely.Hoping theres somebody out there thats done it that can help.+Pluses+,extra power,24db slope verses 6&12 db slope.I have everything to do it,if it's going to improve I want to do it.

then why the heck are you asking - just do it! your system, your ears & your satisfaction.
do it & ascertain for yourself if it's an improvement or not.
why are you asking others for approval?
study the present x-over & figure out if there is a phase reversal or not & figure out how your new x-overs will plug into the speaker seemlessly. Also figure out how you will reverse the whole thing & bring it back to factory spec.
(BTW, I've noted your user-name so that I don't buy your specific Maggie 1.6s ;-) )

The woofer and tweeter crossover slopes are different (as you mention) but the break frequencies are also different. If you use a L/R crossover the break frequencies will be the same. Who knows how the speakers will sound.

Do a search over at the "Asylums". Some suggest asymmetric slopes or xover points. With the Rane, or other 'pro' analog xovers, steeper curves than 12dB/octave are cascaded and introduce more noise.

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.
