Where can I get mid range/tweeter combo for Snell XA-60?

Love my Snell XA speakers but have now got 2 defective mid range drivers. Since Snell has been acquired I cannot find a source.
How are they defective, if the problem is that the cones have deteriorated you can refoam them and that is a fairly easy process. The refoam kits can be purchased different places, I got mine for a pair of Snell J IIs on eBay.
Dead. One in an XA tower and  one in the center speaker. Not sure if it's a crossover or driver problem. 
Thanks. I found them a few minutes ago!
