Default tweeter tweeting to high.....

As the title says ,i have boston acoustic speakers (front) and tweeters. The problem ive always had even with my old alpine type r speakers is that when i raise the treble up, It EXTREMELY EAR PIERCING! Like when your in any other car when you raise the volume usually you get a higher sounding music but the HIGHS arnt to High to the point were you going to get your ears Pierced. So what i have done to get around the problem is put my treble into the negatives so when i raise up the volume it wont hurt but only a tad. I have tried messing with the amp to see if that could help the problem im having with no success. The only thing i can think of doing now is relocating the tweeter on the column to facing the window, but i dont want to spend any money if i can fix the problem on the stock location.


I know this maybe weird but would how high your sit in the seat effect wether you have a more direct line to get what im getting??

I get what your saying. Of course, if the tweeter is facing directly towards you it will be louder try facing them away or down if possible.

Don't they have an adjustment control on the crossover?

This is called having "harsh" tweeters, jfyi.

Tweeters typically have silk or other domes -- silk being the least harsh when playing at high volumes.

You can counter this by locating the hardware crossover (whoever installed them may've put them in the doors or kick panels, or even around the amp. The crossover crontols the DB output to your tweeters and mids. You can set the output to your tweeters there, and turn them down a bit.

The other option is if your setup is "bi-amped", your tweeter could be on a separate channel on your amp, giving you the control to adjust the Frequency/gain there. It's more likely on the same channel on your amp as your mids (if one speaker line goes to each tweeter/mid, they're on the same channel) which would require you to locate the crossover and adjust the volume there.

Good luck

Well, funny you say that because when i got the new bostons to replace the alphine type R they had a option for that. it wasnt till i had the new ones in i noticed that :/. So i checked the new ones and i honestly dont see any were you can adjust them at. Also, there no direct line from the tweeter to the amp it goes to the cross over. So maybe it inside the cross over box??

If I understand your question correctly, my advice is relocating the tweeter and placing the tweeter component inside the A-Pillar. A high-quality tweeter will sound too harsh when mounted in the Sail Panel, and this location is impossible to balance properly for listening by the driver and the passenger.

I have my tweeter inside the A-Pillar, and the sound is very good. Actually, I point the tweeter towards the windshield so it bounces off the glass and the very directional sound from the tweeter is returned so it appears to be coming from in front of the listener. If you direct the tweeter correctly, you maintain left and right, and the driver and passenger hear the channel separation so they perceive distinct sounds.

Here is a picture of my tweeter mount in the A-Pillar.




This is a diagram showing the concept (bouncing high direction sound from the windshield so it comes from in front of the listener bu still has two distinct channels – left and right).



What I am really doing is simply implementing the concept of a bandshell. A bandshell is a large, outdoor performing venue typically used by orchestras. The roof and the back half of the shell reflect sound through the open side and out towards the audience.

I hope I did not misunderstand your question and that this advice is useful.

That statement is only true if one chooses not to utilize a DSP. Over on DIYMA (I think you are familiar with that board), the guys at Harmon Kardon/JBL who were behind the designing of the JBL MS-8 processor which is currently the king of all digital sound processors have stated that they suggest mounting the tweeters in the sail panel over any other option.

You have more experience and expertise than I do, so I default to your advice.

My comments are based in my attempts using the Sail Panel to mount a tweeter, and I have not been able to accomplish a forward delivery and good channel separation with any method or configuration when mounting the tweeter in the Z’s Sail Panel. I also notice that using the Z’s Sail Panel’s small and confined space makes it a poor choice for a better tweeter.

I have had good results mounting the tweeter in the A-Pillar or a floor-kick. I really do not like the poor results and all the extra effort it takes when using the Z’s Sail Panel for mounting tweeters.

I agree mounting most aftermarket tweeters in the stock sails can be a royal p.i.t.a. If you are able to achieve sound that you are satisified with then that is all that matters.

so basically for me to fix this problem i must spend money?? I dont mind spending money but sense i rather do more performance then audio, it takes a lil back seat. So which is the cheaper way to go but get what im looking for? the relocation or what kwame said?

^^ Relocating the tweeters does not cost anything if you do this yourself. If you decide to hire a professional installer, figure about 2 hours of labor. The cost for parts is negligible.

HellSoldier,

My suggestion to you is to locate the crossover box. There will be a adjustment available. Play with that 1st.

I currently have the Alpine type R components, the tweeters are in the sail panels. At the factory 0 db setting the tweeters were really harsh. By experimenting I finally decided on -7db. At this setting it was better but still a little dissapointed.

Using my headunit's built in DSP (AVH-P4200DVD) and buying a mic (placement is extremly important), the sound IMO is great. I did add CDT speakers in the back and a Basslink behind the driver's seat, to fill in the sound, but the DSP made a big difference.

If you do decide on moving your tweeters, try taping a dixie cup with a portion of the side cutout to help direct the sound of the tweeter it will give you an idea of what you will get by moving the tweeters, it may save you a lot of cutting and modifying or another idea of a way of redirecting the tweeter sound. Also try different materials over the tweeter it may help smooth out the harshness.

So you've confirmed you know where the crossover is...

But you aren't sure how to adjust the tweeter db...

Okay. At this point you're lost my friend.

Here, I'll do all the work for you since what I recommended wasn't quite enough. I've found the manual using Google!
