Nice & Congrats!, Post pictures of your step by step progress.
I hope you opened up your 2b's and checked the values on the existing caps & resistors. Just a precaution I know but you never know for sure with vintage polk's till you see first hand.
Do you have RDO's yet?
We can't wait for your future posts saying WHY DIDNT I DO THIS SOONER. Have fun with the upgrade.

Don't forget the 5.8uf's and RD0-198's if you have P/B 2B's.
Ive had the xovers out before as I had to resolder an inductor that the leads had broken off on.No RDOs...YET. Ill get those when I switch over to silver sonic revalation speaker cables and ICs.(And a custom interconnect cable too of course.)Im still debating the 12uF caps though.Im kinda wanting to use the V-caps for the high pass.There VERY expensive (like mundorf.)
It's kinda cool to do upgrades in stages so it feels you have "new" speakers all the time and you can actualy hear what each upgrade has accomplished.
Yo face..What are P/B 2B's. Ive visited this forum every day since I joined and I have never heard of those.
Yo! :D
P/B=Pin Blade.
If you have pin blade 2B's, you can do the 4.1TL upgrade which several others here and I have completed.
Here's a example on a pair of CRS's: http://www.polkaudio.com/forums/atta...0&d=1186358580
OH!...I have b/b... That sucks.Whats the difference between the two.Do they use different crossovers? As I understand it only one blade in my setup carries a signal..the smaller blade.
