Warn Sound Capacitor


hi all ;)
based on your experience, i would like advice on choosing a warm sounding capacitor, its use will be in passive crossover for loudspeakers.

Hi,
@audio4pass
not necessarily as they are higher esr caps and less congested than esa. 
Glad you settled tw level.
I put ClarityCaps on my Great Heils and found them to be "duller" than the Aerovox caps that they replaced.
@ petg60
who has higher esr CSA o ESA ?, are the ESA series that has higher ESR then CSA, i tested them
higher ESR is not always a good parameter
however i’m searching a cap that sound warm and with a good airy.....does ESA to this ?
