Yup; done this sort of thing often, most recently in a pair of Audio Physic Avanti IIIs. In those, the 2 caps in series with the tweeter were a 6.8uF and a 15uF. I replaced both with the highest-quality-composite cap I chose to afford, and this time I wasn't cheap. Altho the highest-value SoniCap Platinum (Teflon-film) cap Sonic Craft lists on the site is a 4uF, Glowacki had a pair of preproduction 6.8s, so I bought and installed them, and the 15uF turned into a 12uF SoniCap Gen.1 'propylene plus a 3uF Platinum. (Claity Caps were original.) Altho I'm no golden-eared audiofile the way some of my friends are, I heard MUCH-cleaner and less-edgy treble, so much so that I was able to increase the average level of listenable treble several dB. I suggest a combination such as I used or perhaps with as high a value of MultiCap RTX you choose to afford with a SoniCap Gen.1 to fill the value to the original.
What is/are the value(s) of the tweeter cap(s)?
BTW, then it's the midrange's turn. :-)
