I have this old pair of Technics SB-3130, they are three way speakers. Both of the super tweeters are dead (infinite resistance) and I’m not sure if this impact the range of frequency feeded to the tweeter. Given the schematic diagram, if I remove the super tweeter, should I modify something to have all the high frequencied to the tweeter?

      Thanks. I haven’t told the whole story. In fact one of the tweeter is also dead. As I don’t plan to invest for such an old piece of hardware (I’m not even sure they are particularly good to begin with), I had the idea to replace both tweeters with a pair of Visaton FR8JS who are cheap, have convincing specs and will fit perfectly in the hole of the previous tweeters. I did not find a match for super tweeters ( and I don’t want to modify the cabinet). The crossover circuit is easily accessible (solderer on the other side of the connectors plate) so il would try to bypass the crossover.
