I have my M10 up and running. I am interested in replacing the tweeters, then possibly doing the x-over upgrades. How do I tell which tweeter this?

    Really? That is very interesting. Looks like the crossovers are up next :)

    No, those are most likely SL2500s. Pull one and check the label on the back.
    The replacement for them is the RDO-198-1.
    Looks like someone replaced one of the woofers, and didn't notch the rubber surround.

    My mistake. Should have seen that since that's what I had in my 2.3TL's.

    Can you explain this? Even if I could see it in the pic, I'm not sure of the significance.
    To the OP: I replaced my SL2500's with RDO-194's (198's require changes to the XO) and re-built the XO's and am very happy.

    Look at the first picture. Notice the rubber around the screw on the right midwoofer compared to the left.

    OK: I think I see the "pinching" going on with the right side. So what's the (sonic) significance?

    Not a sonic problem, it's a installation and lifespan problem. The rubber surround has been stretched, possibly torn, and the adhesive bonding the surround to the frame may be compromised.
    The correct replacement for the SL2500 is the RDO-198-1, not the RDO-194-1.

    Oops...I must have had SL2000's, because I know the 194 was the replacement. I should edit my other post.

    I did replace that woofer. DId not even think about notching it. Just very carefully cut a triangle with a sharp hobby knife?

    Either copy the notch like the originals, or cut a half circle. I use a bolt and nut as a guide, and carefully cut around the head, leaving a minimum 3/16" of rubber still attached.
    Round is better than sharp corners, less stress, and less chance of splitting as the rubber ages.
