Help with crossover capacitors

Bill/Grannyring- I was just looking at those resistors and it's definitely worth giving it a shot at replacing.  I will include those when I do the work.  I am currently looking at either Clarity CSA caps or Mundorf Evo oil caps.  Each one will cost me about $150 total to re-cap at the same values.  I think I've got the idea, I just have to go back and check the resistors on those speakers and make sure I get the correct ratings.  I appreciate everybody's comments and ideas.  It is very helpful and is making this all fun.

HCouple of things to consider. The Evo caps have a sound signature that is more hot in the presence area. They sound a tad tipped up in the highs and upper mids and not as full bodied as the Clarity. The Clarity CSAs are more even handed in the highs and upper mids and sound more natural based on my experience. If you are looking for more sizzle and energy in the upper mids and highs the Evo would be a good choice.

Parts Connexion is having a 25% off sale and the Clarity caps are included. Perhaps even the Mundorf? You should be able to recap within your budget. The 3uf caps are $6.75 each and the 5.6uf caps are only $8. 

I would prefer to not have anything hyped but realistically it's all going to be a proper upgrade.  I will check the sale.  I thought the CSA's were more expensive than that, but I will order them now if they aren't.

The 5.6uf caps are not available.  Could I just use 2x 3uf caps in parallel to replace the 6uf caps?  Then I just order all caps of the same size.

And another question:  The resistors are 30ohm 15watt and 15ohm 10watt.  Mills makes both of these in 12 watt versions.  Will this work?
