Upgrading Kef R100 crossovers

I just picked up some R100’s and am really liking them.  I think that I like them enough to try to squeeze every ounce of performance out of them and am thinking about upgrading ghe crossovers.  There are only a few components so I don’t think that it would cost too much $.  I am not handy with a soldering iron so I’d rather just send the crossover schdmatics to someone and have them send me back complete, new crossovers that I could just plug and play.  

Where / who could do this for me?

And while I am at it, would replacing the batting inside with some no rez be an improvement too?

Thanks ahead of time for any info on this!!

I contacted madisound and gave them the Kef R100 crossover schematics (that kef promptly emailed to me).  
Josh from madisound got back to me in a matter of 5 minutes with options and pricing.

wow!  Great service from kef and Josh from madisound 👍👍

I’m surprised you aren’t supportive if me custom tuning my speakers for my ears

Get yourself a dsp crossover and get retuning then.

Have you priced those caps? Cost prohibitive, for sure The coppers, 5uf 100v 200.00 +  20uf is over 400.00 discounted.. 100 volt cap.. There a lot of great XO caps. Danny has more than one selection, or quality of cap, I'm sure, I hope!

Maybe the band pass xo for the mids/highs.. It could cost 2k for a 4 ohm 3 way.  100 volt... man oh man..

@kenjit , do you have any recommendations regarding dsp?  And I don’t have the money really to buy extra amplifiers...

also, do I bypass the crossovers in the speakers altogether then?  I’m trying to send the signal through higher quality components...

@bryhifi , I’ve seen contradictory statements within a single response.  It was something about mdf being junk, then 4 sentences later he said it was great.

Kenjitt, like my Mom, can argue with themselves as well as we can 🤷🏼

you could get the hypex plate amp or mini dsp plate amps. You will need to find a way to mount them either into the cabinet or onto it externally. Then you start tuning the speakers. You select various slopes, crossover points and time delay. You compare the results by ear. You adjust the eq too. You will need to put in a bit of baffle step compensation and a gentle downward slope. 

Yes you bypass the passive crossovers.

Very helpful and complete reply!  Nice job - seriously!

@audiokinesis , I know, right?  I do respect the guy for not really ever stooping  to level I do with the insults. Maybe I can learn something from Kenjit after all 🙂.

@b_limo , I agree with you, and definitely respect Kenjit for the restraint he shows as far as not "replying in kind".
