hahahah. the rsd's aren't the best, there really is no "best" speaker. the rsd's are very good though, just good all around. just a good sounding set that happens to take an *** load of power. passive crossovers are just passive crossovers, the crossover points are preset where PG thinks they might sound acceptable in most installs. the right way is to go active and set your own points and slopes. the rsd's crossovers are nothing special, and in my car didn't work to well.
also i started a thread on
diymobileaudio.com to see if anybody over there has heard anything about the Ti mids....
