Well this is weird, my ST:TNG tweeter was blown, so i changed it.
Changed the speaker, the cap, resoldered wires from the mid speaker, tested continuity, the other speaker hooked to same wires works fine (the mid speaker), any idea ?
Can the high frequencies be filtered from the sound board somehow ?

You also could take a DVM multimeter and measure the continuity / ohms across the tweeter directly on its two connectors (e.g. bypass the cap), once disconnected from the machine. You should read a certain resistance value. If you read open, then the tweeter is burned. (True for most types of tweeters).
Given it is only a tweeter, you also can plug it with its capacitor, in parallel to one side of a stereo sound system speaker in your house, at low volume setting, and see if you hear any high frequencies from it; if not, the cap and/or the tweeter is/are bad.
The following are reasons why a tweeter can burn: - too high power too long for the unit; internal small coil overheats and quits; - broken lead wire from lug to inside the unit; - presence of low frequencies (e.g. capacitor in-series 'leaking', or too large cap value) - presence of high-frequency noise from the amp, possibly not hearable (higher than 20KHz) - DC voltage/current across the tweeter (bad cap and bad amp).
