Look for the New Clarity CSA, c for Copper ends a excellrnt cap for the money and clear  you have roughly 5% you can go over tolerance wiithout issue..
I have a 68uf cap in the Leonitis crossover this way my Voxativ driver just operates from 350hz on up.  Just factor in a 15uf clarity 250v which is more thrn enough volts, a 3.3Jupiter copper, and a 2.2Arizona Blue cactus  Jupiter condenser 
Sells both caps  that is s perfect match . The Jupiter is a 100v  for Loudspeaker
You are pulling less then 15 volts on average. Good luck and slliw a minimum of 300 hours runin 

Please note ,call Jupiter condenser ahead of time,
Chris doesnot all ways have the 3.3uf 100v Jupiter Copper foil made.
If not get a date and secure them,  that extra 1uf  makes a small additional difference Worth the wait ,if you can't wait just reverse to cactus Blue 3.3uf.
Please note put a drop of hot glue on all leads where  coming out of caps a little fragile
And any bending hold with one hand at least 1inch from where lead comes out for support No one wants to ruin s $200 cap ,or any for that matter.

For a large value cap like that I think the best sounding large  value cap is the Mundorf EVO Supreme Silver, Gold, Oil.  They are expensive, but the best large value cap I have heard. Watch the size of the Jupiter line when the value gets big as they are huge! A 15uf Jupiter VT cap is 5 inches long! 

I also like the Clarity CSA as Audioman68 mentions. Not as good sounding as the Mundorf above, but still good and very affordable. 

I don’t like mixing brands ands materials of caps in speaker crossovers. I would stick with one brand/type. You can combine the same value to get your end value. Best to split evenly such as two 10 uf.  10uf and 5uf is also fine. Be sure to get them matched within 1%.  Sonic Craft will do that.  

Thank you both for the excellent suggestions!

@grannyring I've heard that as good as mundorf silver, gold, oil is - it is little on the leaner side. That gives me pause. I've some Jantzen silver zcap 22uf. Last night I put them in and the sound became detailed but lost some musicality. But this same cap sounds superb with Voxativ. Not so much with horn. Hence making sure to go with less detailed (no silver), musical, smooth and organic sounding cap.

@audioman58 Great tops about hot glue. Btw, I don't think there's enough space to fit all three caps on the crossover board. If I've to pick two caps, Clarity CSA + Blue or Clarity CSA + Jupiter?

What do you mean no room ? Is this on s munforf screw down board ? 
If space needed I put the 2 bigger ones together between dome hot glue 
,and sit the smaller one ,cactus in between. No 3. If Jupiter's available 
I was told . Go with the 3.3 Arizona Cactus Blue, and a 2.2 Jupiter Copper,
15uf Clarity Csa,250v  there will be enough room .  
Myself took 2 1ft ,1inch thick Birch and mounted Xover to it .
Had Verastarr make me s longer wire harness by a foot longer progressive per driver . If you don't have the Verastarr cables ,for sure get them .
Bigger difference thrn the cap upgrade the stock wire it comes with ok,
But not in the same League .  Greg  Weaver- Stereo times gave me the hint 
He did all power cords ,then expanded. The owner Mike Powell,
Totally stands behind his gear. $$ back if not happy Period.
