Response from Clarity Caps mfgr
I emailed the manufacturer of Clarity Caps asking if they could specify which end was the outer foil, and they responded:
"Thanks very much for the email. Unfortunatley there is no way to tell which end of the capacitor connects to the outer and inner turns unless you unwrap the tape and the first wind or two of the film. For customers who request us to mark the capacitors as such we identify them at the winding stage of production.
Some manufacturers mark the different ends as a matter of course whilst others such as ourselves, Mundorf, Solen etc don’t. We have carried out major research into audio capacitor performance and construction over the last two years and feel that the more significant factors to performance is related to controlling the manufacturing processes to reduce sonic output caused by mechanical resonances rather than factors such as orientation. Our products concentrate on these factors. I am attaching a brief document showing the research undertaken and a synopsis of the findings. A more technical paper was recently presented at AES in Amsterdam and was very well received.
For now we would suggest that you try the capacitors both ways and adopt your preference. We would be reluctant to advise which way to orientate the capacitors within the crossover even if we had marked the outer turn end. This is open to user subjectivity and we wouldn’t assume to kow your preferences better than you.
I’m sorry that aren’t able to offer you a definitive solution to your immeadiate problem but if you want to discuss further please don’t hesitate to get in touch. Best Regards..."
