My RSDs are for sale for $55 shipped, thats with Power Acoustik NB-1 tweeters, not the RSD tweets. just throwin that out there. I might try the CDT Pro's when i sell these.
There is no such thing as "CDT Pro's" I'd be interested to know which made up set from woofersetc you're looking into. Chances are it's not up to spec for crossovers, etc. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
Looking at the specs on the CDT's don't expect much midbass with a 100Hz xover and the silk tweets will probably be pretty mellow compared to a metal tweeter.
