My situation is somewhat similar. I'm combining Jensen RP-302 tweeters to Altec 756Bs. There is an approx. 3 - 6db sensitivity mis-match between these drivers.About 6 or 7 years ago I started with Mundorf Silver/Oil .68uf caps and it sounded fine. A few years later I switched to Mundorf Gold/Silver/Oil .56uf caps and it sounded even better. About a year ago I switched again, this time to V-CAP TFTF .47uf caps. This sounds the best.
The RP-302s are 16 ohm, so with the .47uf caps, that puts the roll-off frequency at approx. 21,200hz. This was intentional to compensate for the sensitivity mis-match, but is it wrong? The high frequency response of this system sounds very good to me and everyone else who has heard it.
