Help with crossover capacitors

I would stick with the original values. Easy to do. Don’t accept 7-10% variance! Order your caps matched within 1% for right and left speaker. Don’t buy Dayton. If you don’t want to spend much, then get Clarity CSA 250v. They have a 3uf. For the 6uf just combine a 5.6uf with a .33uf 630v.

If you are ok with spending more look at the Jupiter VT line. Best to stick as close to the original values as possible.

Also, replace those sand cast resistors with Mills MRA12. Much better sounding!

Go with the Clarity. Yes they sound better in every way compared to the Dayton caps. No contest. When combining caps to achieve the value you want you simply parallel them. Stack them with the small one on top and simply solder the leads on each end together. 

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. 

Goodness Miller look at my feedback and the fact that I build and modify gear and cables for a living now. Been at this for years. Strange comment. Anyway, what I gave for advice is very straight forward, reasonable and smart.

Also, replacing those sand cast resistors with Mills MRA12 will also pay off nicely sonically. They cost $4 each. I would be willing to help you plan this out etc.... Done this for many A-goners.

I have upgraded so many speaker crossovers over the years that I lost count. I have vast experience with cap and resistor brands and have done the critical listening tests over and over. It is my particular passion and joy. See my virtual systems for some of my speaker and amp upgrades as well as tube amp builds 

Have fun.

Yes on the two 3uf caps.  Now you’re thinking! Yes, the Mills will work fine. 

Alex is spot on as I use the .01 Duelund tinned copper cap all the time. Only issue is they are out of your total budget unless you splurge 😊. 

Ha! Have fun.   You can improve the sound of all your gear with your skills as you learn! Every piece of gear I own has been upgraded and sounds better than stock.  Very satisfying and fun hobby.
