Caps in crossover for midrange question

[goodguys]

Hi Thanks for reading I'm using a single 10uf cap in series with an 8 ohm midrange unit, giving a crossover frequency of 2khz @ 6db/octave

I had bright idea of replacing the single 10uf cap with 10 x 1uf wima polypropylenes, i thought with so many caps paralled up it might give lower esr and reduce some of the other undesirables elements of caps. Now the sound is all weird, sounds wrong, i don't know what is going on.

Have you tried anything like this before, or heard anything

Measure impedance of a 10uF capacitor. Save it for comparison purposes as a .zma file.
Measure also all of the smaller capacitors connected together and save the file in the same way.
Load these two up in a simulator to inspect how they align.

Have you looked at what the ESR is for the 10 and the 1?

Thanks. I don't have the equipment to measure such low esr which should be a fraction of an ohm, i'll have to look at the manufacturer's spec sheet to learn more. The 10uf is a clarity cap esa, and the 10 x 1uf are wima mkp2

Wima specifies ESR through tan(delta). It's around 0.1 ohm at 1 kHz.
