Recapping crossover, odd value series combinations?

[srdjant]

Hi there,


I'm thinking of recapping my Mordaunt-Short MS35Ti with new caps.


The originals are 4uF for the tweeter, and 7uF for the woofer.


I can't find direct replacement 4uF caps for the tweeters. The closest I can get to is to put 12uF and 6uF Alcap Low Loss non-polarised electrolytic in series. That should get me 4uF.


Is there any issue with putting different value caps in series for the crossover? Will it mess with ESR or sound quality if they are odd values?


Thanks

It's much better to use parallel capacitors instead of series. You should be able to find
two or three smaller value capacitors that add up to 4uF or 7uF when in parallel.
Certainly you can use four 1uF in parallel.

Lower ESR with parallel capacitors, smaller size, and lower cost also.

Claritycap CSA or ESA series in 3.9uf and 6.8uf would be suitable replacements.

Claritycap is polyprop, so I ordered Alcaps from Falcon Acoustics, with the 4uF being also a polyprop.
Will see how they sound, if no good, will get from Claritycap.
