Tweeter harshness
 

Why is it that when I turn up the volume the tweeters don't sound very good? It mostly happens when someone is singing and they make an 's' sound. Is this normal for most tweeters? Could it be my amp? Please help this is startingto irritate me

is this a comp set? do you have the ability to change settings for the tweeter? might need to look at an L-pad

Yes it's a jbl gti608. I've got the tweeter setting on the crossover at -3db and have turned down the highs on the eq. What's an L pad?

its a device used by some SQ guys to tone down the tweeters in a system. i dont know the technical side, but it greatly decrease the volume of the tweeter

I've had those comps up front, and still have them in the rear. The tweeter is excellent (very detailed and very clean), but with certain source material, particularly poorly recorded or low quality tracks, the sibilance (harsh "S" sound) you're hearing can be pronounced. They are titanium dome tweeters (which tend to be bright, metallic sounding), but have a rubber surround to dampen those types of resonances which makes them much smoother sounding. Try different tracks of cd quality or first gen mp3 of 128 kps or higher, and experiment with different mounting angles for the tweeters. Unfortunately, there are certain tracks that just don't sound good with certain equipment or with any high resolution speakers (the speakers tend to bring out the track's limitations that may not have been noticed using lesser equipment such as oem systems or cheaper speakers). I don't have this problem at all, and mine were/are pointing right at my ears and getting 50 watts rms each....however, i use active crossovers and processing...and I've never used the passive cross overs that came with the set (that may be a factor); I also, only listen to high quality first generation rips at high bit rates and or cd quality tracks.

How about a list of the gear you are using and what you are listening to on what media? The problem you describe can have many sources including but not limited to:
- tweeter breakup
- Amp clipping
- Passive crossover saturation
- Bad source material
etc..

Well all the stuff I have is as follows
components: jbl 608gtimk2
amp: mtx thunder tc4004
headunit: jvc kwnt3-hdt
and I'm using a USB flash drive for music.
most of the music I have is 192 kb or over so I don't think that's the problem.
I'm using the passive crossovers that come with the component set.
My amp however is only 65 wrms whereas the speakers are 150wrms a side

There is a very different sound between metal and non. Sounds like you should have went for a component set with silk tweeters... they are much easier on the ears.

Are those tweeters on axis?

I'm not sure what u mean by axis.
As for the silk tweeters the last component set I had was a jl set with soft tweeters but they did the same thing. Is there any way of finding out whether my music is messed up in the higher frequencies?
