Recapped my crossovers and the speakers still function - one hurdle down. Many thanks to F1nut for the excellent topic explaining the details.
Now, I purchased a pair of RDO-198s off of eBay to replace the SL2000s, and have run into a bit of a snafu. I guess I actually have a couple of questions:
Any way to verify these are actually RDO-198s? They have no identifying markings of any kind, and they look just like this picture of the RDO-194s I found, although it comes captioned that the two are very similar looking.
The SL2000s are connected with two identical sort of spade adapters to the end of the wires. The new tweeters have one larger than the other. I take this as a possible sign that these are indeed RDO-198s, as the RDO-194s are supposedly "hot swappable", but I figured I should make sure before I go soldering wires to them.
One last question: one post is red and the other uncolored; am I correct in assuming the red is hot and the uncolored ground? Does it make any difference if they are connected backwards, as long as the two tweeters are connected in the same manner?
I appreciate the help.
