B&W CDM- bad crossover????

I have a pair of B&W CDMs that I bought on ebay a year ago.  I tend to buy speakers I don't need and felt I got a good deal.  After about 6 months or so, I finally got around to hooking them up.  There is hardly any high frequency output.  At first I thought the tweeters were fried, so I found some replacements from Madisound or PartsExpress.

It was a relatively simple job, but they sound exactly the same.  So now I'm thinking both the crossovers have issues.  Any advice on how to proceed would be helpful.

Of course the seller stated they worked perfectly when he had them.  He used them as surround speakers and wanted to sell them after he torched them or they stopped functioning properly.
