The one tweak most Focals need ...


From a lot of work done analyzing Focals, if you have one, especially an older one, and want to improve the sound and maybe learn something, try upgrading the tweeter caps.

Usually this is 1 or 2 film caps in series with the tweet. I can recommend Mundorf MKP as well as Clarity CSA as being good improvements.

Of course, you probably wouldn't want to mess with your Utopias, but for the mid to low end, highly recommended.

There are three ways for you to go I think:

1 If you want to try inexpensively, update any caps in series with the tweeter and midrange.
2 Get a miniDSP and attempt to EQ your tastes into the speaker
3 Get a brand new kit.

The hardest thing for newbies to do is take an old speaker and switch a single driver. It's a lot of work, and may not be worth it due to the quality of the parts involved in the original, the cost of the new crossover, etc.

This is totally a great learning exercise. You will learn speaker measurement and analysis, you'll get new tools, and be able to dial in exactly what you want, but .... it is ONLY worth doing if you want to invest in yourself that much. To do it to reuse the parts you have, not really worth it at all.
Hey @johnsonwu

I agree with you about the caps, but sometimes DCR in a coil is a good thing, as it can be part of a baffle step compensation.  Don't go reducing that without understanding the circuit.

Especially in shunts like Zobel or notch filters.

I guess if I could describe the Mundorf MKP by comparison to Focal/Solen it is darker but a lot smoother.

The EVO scintillates. Adds a lot of color saturation at the mid/top end which is just not natural to my ears. That + the way those inverted domes sound naturally makes it go the wrong way.
The Clarity is more smooth, and also not nearly as dark as the MKP. It _is_ a better cap in absolute terms than the MKP, but ... like the Batman, I like the darkness. :)
Hey @auxinput

I so don't like Mundorf's top end caps at all, that's why I didn't suggest them, especially not with Focal's tweeter behavior.

Then of course there is the physical size ...
Hey @audioman58

I like Clarity a great deal and the Audyn Copper line a lot also.
However in this particular case, I think you'd be amazed at how much better Mundorf MKP's are to Focal's default.

Still, yeah, Clarity and Audyn is better. Audyn, like all copper caps, are HUGE though.

I'm a little surprised! I thought CSA's ran a little larger than Mundorfs.

Do let us know!

Hey @auxinput -

Smoother is exactly the word. I find the Solen caps Focal uses to be really pretty harsh sounding. I prefer Mundorf MKP's relatively to those. though not all agree.

Clarity is less dark, but also a lot less harsh than what Focal puts in.

I suggest that experimentation here is your key to learning. Try it and come back and tell me what you found. :)

Best,
Erik
Those tweets are hard to replace.


 The Mundorf MKP’s are cheap and to me, a big improvement.

Give them 48 hours to break in.
