Fostex FT17H - hurts my ears. Hi, I have build some time ago speakers with fostex ft17H tweeters. With low volume they are ok, But on louder volumes they tend to hurt my ears, especialy if there's is for example a triangle in the music.
Very sharp, resonanting sound. It isn't the amplifier or cd player. Are there people who have the same tweeter and had the same problem?
Mabey the 6db cuttof isn't sharp enough and the driver hase brake up problems? First I thought it were my ears, but a friend experienced the same. Regards, Anne. I do not know this tweeter but it might be running out of excursion? Try increasing the order of the network and see if that helps.
Every five minutes there's a bomb or somethin'! I'm leavin! Now with website! Can you describe your speaker in more detail? What is the other driver? It sounds to me like the supertweeter is crossed to low. Using a 1. A crossover at 10kHz will probably require a steeper crossover. I suspect that it isn't, especially after the baffle step. Only measurement can tell for sure. The FT17H's Fs is apparently 5kHz, if so it wouldn't be the first tweeter to have problems driven at a reasonable level at its fundamental frequency.

IMO, the supertweeter should be padded down even more, like 10db. Besides, if this is out in the room rather than flush against a wall, there will be some additional apparent treble 'gain' from the baffle step. I finally gave up on my 12LT - or more accurately - tweaked it to death. It finally ended up with no whizzer and a piezo for the highs. Besides the bass being punchier and more effortless than a bass reflex, the midrange seemed clearer and more natural.

No problems such as described by the original post. It isn't possible to increase the crossover frequency since the 12lt get's to 9 - 10Khz.
