Help with crossover capacitors

I am re-capping some Altec Lansing 890C Bolero speakers.  They have 6uf/50volt and 3uf/25 volt caps.  What will change if I use 5.6uf and 3.2 caps?  I can't find the exact 6uf and 3uf values.  Should I go a little bit higher on those values or lower?  Any suggestions?  I'm looking at Dayton, Mundorf or Jantzen caps but I'm open to suggestions.

Great.  I think it will be fine as I really don't push them too much. Thanks for commenting.  Everyone on this thread has been so helpful.

And another question:  The resistors are 30ohm 15watt and 15ohm 10watt.  Mills makes both of these in 12 watt versions.  Will this work?
Two 15ohm 12watt resistor in series will give you a 30ohm 24watt.

I get that, but does that actually deliver more wattage to the speaker? Or does it give headroom to the circuit?

The resistor power rating is the maximum amount of power that the resistor can withstand. It won't give your speaker more power, I believe the designer use a 15watt resistor for a reason.
