Speaker crossover mod. Your advice?

I'm considering modding the crossovers of my Focal 1027s. Specifically, I am thinking about replacing the capacitor associated with the tweeter. I have received some helpful advice from another A'gon member who has done a similar mod to his crossovers (on a different model speaker from the same manufacturer).

I would greatly appreciate any suggestions from folks who have experience with this sort of thing. In particular, what sort of improvements can be achieved with this kind of mod? Any thoughts on which caps to use? Any common mistakes I should avoid? Is the whole thing a bad idea?

Thanks for your input.

Hi Bryon,

yes, midrange driver. Here is a photo of mine: http://img855.imageshack.us/img855/4416/mid6w4361back1.jpg.
If you like, you may look on the second mid driver, whether the label is there better readable.
I would assume, that your 1027 BE was later produced an may have been improved a bit. On the crossover C1 changed from 3.9uF to 3.6 on your board.

The other midrange was too faint to read as well. Judging from your picture of the rear of your driver, I'd say our midrange drivers are the same. So I don't know what to attribute the difference to.

Hi Bryon,

thanks for your help. In the meanwhile I could get in contact with someone of the Focal service. He told me, that the mid drives of the S and BE are the same but the casing box construction and the crossover board differs. The S is softer tuned. The S doesn't have the beryllium tweeter.

I hate to break the news to you BUT the best crossovers is NO crossovers AT ALL ! Crossovers just degrade the sound !
