Can I replace a 24uF capacitor with 22uF?

I am planning on replacing the Bennic caps on my Tannoy Turnberry SE low frequency crossovers with either Mundorf Supreme or ClarityCap MR, depending on how many caps I need to buy. Currently there are two 12uF caps in parallel. Can I just replace these with one 22uF cap without hearing any significant shift in frequency balance?

24uf of Clarity MR is quite expensive. I'd suggest using a 20uf Clarity ESA 630v and parallel a 4uf Clarity MR for the final value. That'll give you 95% of the benefit of using the MR for full value.

Possibly not "significant" but it depends on the type of xover.
Tannoy usually voice their products very carefully and I would urge you to just replace the caps with the exact same values.

Vapor1, I am intrigued by this idea. Can the 4uF cap really have that much influence even though it is only roughly 16% of the total capacitance?

Clarity can make whatever value you need, they are very very good caps.

The Clarity MR are large caps btw.. I would be inclined to parallel 2x12uf, as the circuit was designed with that esr in mind i would have thought.
