View Full Version : Why the hell are the tweeters so bright?

On my last two set of components, the tweeter has been ridiculously bright (diamond hex and ID CTX165). How bright, well they almost make my ears bleed with the highs turned all the way down. And when i turn everything on flat (like a real system is supposed to be run) they are literally unlistenable. They also give off a really harsh sound on certain vocals and guitar parts. It's like the mids are only playing at half potentia because they can't catch up to the bright tweeters.

Now before i go any further, i have my crossovers all set at 80, with a 12db slope. And on my 5 band EQ i have the highs at 4k because if i go any lower or higher they give off unnatural harsh sounds. I also have a set of resistors in their to try and decrease the brightness, but like i said, they are just wayyyyyyyyyyyyyyyyyyyyyyyyyy too bright. And what riddles me is the fact that they are unlistenable at a flat EQ.

I need some help , i have to be doing something wrong.

Are you using the passive that came with them too?

What and how many xovers u got? List it for me

what do you mean you have the highs at 4k on your eq? Are you cutting or boosting that frequency? Also where are your tweets mounted? Do either component set come with a -3 or -6 switch for the tweets?

Are they metal domes?

Dont know about ID's domes, but Diamond's metal domes are known to be screamers.

focal tweeters too imo

x2 on the aiming of the tweets. if they are positioned at your head they will be stupid bright.

Also if your running active and passive and cutting its all off to start with.

You're confusing a flat response to the ear with leaving everything on "flat".

My suggestion is to choose ONE xover and see which u like more. Leave the active flat.

I agree with JimJ, EQ's are made so you can cut and boost to your liking, not to leave all settings at 0db. Good Luck!

Leaving the EQ Flat is flat level 0 gain +/-. Once it is set it should not be changed on the xover. You use a preamp or other controls to cut.

you said you are using resistors? on what? that line to the tweets? if you are using the passive xover it will not work properly any more..

What wont work properly anymore? I am using the passive crossover and i have the resistor connected to the tweeter wire in it.

You know, on the 5 band EQ, the one that goes from 2.5k, 4k, 5k, 8k, 10k, 12k?

I have that on 4k.

No frequencies are boosted.

My component crossovers say they have +3 0 and -3 but i can't tell which one it's on, and can't figure out a way to change it.

brb searching manual.

Use one OR the other. If you are using coil/caps passive that is changing the frequencys from the active crossover. You dont need to run both.

AudioDave
03-23-2010, 11:43 PM
the middle is flat usually. Remember too that you are only cut/boosing THAT specific freq. not the entire line.

Caps? You talking about the resistors im using? So should i just take them out?

did you ever answer what vehicle or how they are mounted? if they are on or off axis? I know with my id xs28s on axis they were hella bright (not the same tweeters you have) but now that they are off axis and properly tuned they sound beautiful.

hell if he had the xs the tweets would be the only thing he would have to tune.. just an hpf for the mids

Dude follow watt rating of the components. Get rid of the extra resistors. Try with only the amp - Passive xovers and speakers 1st.

Then change it to Amp - active xover NO PASSIVE Caps and speakers

Go with whichever situation you like the best. Thats it.

i have similiar problems with my HSK165.4s with stock mounting locations, the tweeter is pretty high and close to me in the door so i think it's more placement rather than faulty equipment. With a parametric HU and no external EQ, i dont have much room for adjustment. They also lack alot of mid-range detail. I ended up keeping the EQ flat and the crossovers set on -2db. I still wish for more mid-range but when i set the cross to 0db and reduce the top end, it just sounds unnatural to me. Adding more midbass in the EQ also sounds weird, that's why i'm living with just flat and -2. They're still a tad bright on certain songs, especially trance but i'll just have to learn to live with that.

well if you didn' cut or boost the value you have selected is irrelevant, your not doing anything too it lol. Try cutting each one and see which one is the worst offender. You have 5 different EQ points to pick from all in the tweet range, use it. Also the adjustment switch is usually on the front face of the crossover itself.

Maybe its the set? I heard a set of CTX and the tweeters were bright as well. Sounded fine to me, but to more discerning ears they might be a bit much.

this is not the problem! having tweets on axis is a good thing, never a bad. there is an issue with the amount of power the tweets are getting and exactly what signal they are getting.

yeah.

he's too high on bass. Home audio, cabinets, bookshelves, and monitors must be stupid bright with tweets on axis.

Keep in mind that tweets do not need very much power at all to get "loud", also you said you had it at 4000hz, if you are boosting or cutting at 4000hz the super tinny crazy loud part will be higher than that and you are doing nothing to fix that. it sounds to me like you are a little in over your head with the amount of adjustment and additional components you have at your disposal. Go back to basics. no boosting or cutting, simply one chanel of power going into your passive everything set flat, no additional caps/resistors... speaker wire going to your tweets and mids from the passive crossover that is set all flat. make sure you head unit is set flat, and that there is no processing at the head unit, the loud button is off. make sure the amp is not processing the signal any, other than low pass to protect the mids. Start with your head unit set to 50% and the gain of the amp at 0, then advance the gain to the point where the tweet is comfortable to the ear and fairly loud. At this point is it over powering the mid? if so use the cut feature of the passive and cut it 3db. is it still over powering the mid?... I can go on from here if you still have issues. but unless you have the tweet right at the top of the A pillar next to the roof and 18" from your ear, you should not be over whelmed from the tweet. You may have to detune it a bit, cut some of the higher frequencies to make it sound a bit more natural, but is should not be "killing" you
