Replacement tweeters for tannoy p10

I am trying to fit a pair of audax tweeters tw025a01, to my tannoy's p20.  After breaking in the tweeters, found that they dont blend in together very well, So i tried a few things and found that a step baffle compensation of aprox  -2dbs (2ohm resistor in parallel with .56mh coil)helped a bit. i did connect the filter in serie to the woofer, before the woofer crossover. 
 My question is, Should i connect the same compensation in parallel to the tweeter, and does this make sense?

You need a ton of info to get right,  if you can get it right...if there is any pad in the original crossover that can effect the bsc.... The only Audax spec that I have is on a TW025A0... not the 01 version. Do you have a schematic from the Tannoy?  It isn't likely that the Audax is a direct drop in, you'll probably need to change a piece or two in the tweeter circuit besides BSC.
I assume that you measured DC on the tweeter and the width of your cabinet to figure BSC? 
If I can get enough info, I'll be glad to help,  Tim

Did a bit of reading on the audax tw025a0, found that the tweeter has a 6db drop after 4000hz. Think ill go with custom crossovers, not sure if i should cross them at 2200hz, or 4000hz?
  Current tannoy p20 are at 3000hz. I'am using loudspeaker design 2 on the link.

Well, the pdf I saw showed about a 4db drop at 7K.... Go here and confirm which tweeter that you have:
Go to the old Zalytron site.  www.zalytron.com
Left side, click on audax, scan to the bottom of the page, click on pictures & specs.... on the next page,  you see a French word for Archives...go into there. Find your tweeter and let me know.  Tim
