I've been looking around and have located two pair of of the tiny CRS models as opposed to the giants I bid on last week!

Anyway, one pair has has the single tweeter and the other pair has the twin tweeter. Is the there a general consensus as to the preference of one or two tweeters?

    I think they (polk) started with the dual tweeter -- one tweeter was for SDA effect. The general consensus (i've never heard the SDA dual tweeter design) is that there are some unexpected effects with the dual tweeter - depending on the original music source.

    i.e. - the single tweeter design is evolutionary and preferred (by most) (i haven't heard the dual tweeter)

    The CRS+ (one tweeter) are the preferred generation of CRSs. If it is one of the pin/blade run you can do a 4.1TL mod upgrade to the crossovers. This will allow you to upgrade the tweeter to an RD0198.

    I still have a pair of CRSs (two tweeter) and while fun to listen to can give you some non-musical effects like instruments/vocals flying overheard or coming from behind you. Actually these have made their rounds around the forum. Jesse did the woodworking and Mark did the binding posts with Vampires, I don't know who installed the RD0194s.

    If you buy a set of CRS+ see if it comes with the original stands. If you buy them and it doesn't come with the stands, email me and I have two pdf's that have drawings and the dimension of the stands I can send you.

    So would I assume that a blade/blade is not upgradeable to 4.1TL?

    Yes, but maybe Ben could do something about that.

    I have a 2-tweeter CRS, but never heard the 1-tweeter version. My impression is the 2-tweeter speaker is excellent. I have pushed them with a Halo A21 and paired them with a tube phono pre and preamp and Paradigm Reference 15 subwoofer. I absolutely love them. Me thinks that too much is made over "preference". Anybody heard a bad SDA loudspeaker? Relax, take either pair, feed them well and enjoy! :D
