Hi all, thanks for all the reply. Let me describe what happened until today since I got my super tweeter (ST).
All these while I have been connecting my super tweeter like the picture below. (I connected the ST raw, no box no enclosure or anything)
1) I started off with a 2.2µf capacitor only. I find the sound too sharp with a lot of 'sstt sstt' sound.
2) I assume I din get enough µf and I got a 3.3µf cap and results were more or less similar. Then I combined 2.2 and 3.3 and sound still quite sharp.
3) One day, I went to buy a 0.8µf and 1.2µf capacitor (i got a range of caps now) to experiment.
4) I find the sound of the ST very quite affected by the volume from my receiver. Soft sounds ok but once I turn up the volume, sound is very sharp with a lot of 'sstt sstt' sound no matter what µf I used.
5) I am using Belden 1307A cables for the ST and my mains are JBL studios S310ii 8ohms if you guys need to know.
6) I admit the vocals are much better now but the sharpness and 'sstt.. sstt..' sounds are quite irritating and I can't really volume up.
-Is the lower the µf the higher the pitch or the higher the µf the higher the pitch?
-Will adding resistors to the ST help? If yes around what value I should be looking at and how to connect them?
-Will using thinner tin cables help? The Belden 1307A is the thinnest cables I could get for pure copper as I think pure copper will produce warmer sound.
