Is there a way to reduce brightness of a speaker

[thermonuclear]

I have a set of Soundstream 6x9's I just installed running off an MTX 4244 4 channel amp bridged stereo. They are 120w speakers. They are just too bright for my tastes. Is there anything I can do to tame the tweeters a little bit? They are extremly lound and sound good just too bright and I already have the tone control down a little from 0. I don't want to just turn down the tone because it affects the front separates as well and they sound good where they are. Can I put a cap or something just on the tweeters of the 6x9's? Or fatten the drivers up some to counter the brightness.

thanks

If the tweeter has a cap on it already, you may be able to replace it with a smaller cap. This may not be the technically perfect answer but I think it would achieve what you are asking. This could also be done by adding a small resistor in series but try the capacitor first IMO.... the effect is different.

If the tweeter does not have a cap, it may be a piezo tweeter. Adding a cap will also work but in a different way. You would want to measure the tweeter with a capacitance meter first, then add a capacitance in series that is (for starters) maybe twice that value.

Have you tried using a non-polar capacitor in parallel with your speaker?

the higher you go in capacitor value the less harsh it will be

try 4.7uf, 5.5 uf, 6.7uf non polar...those yellow ones...that look like they have wax on the ends

Turn the darkness up!

Really, is it possible to disconnect the tweaters leads that connect to the woofer leads and go bi-amp? I used a 4 channel amp to do this, it helps when dialing in a xover frequency also gains can be upped or downed to blend better. If your going to mess with the caps maybe going bi-amped would be preferable.

L-pads could be installed if your going to take a soldering iron to them. Might be a better bet than taking away the xover set by the caps???

Go with speakers that have silk dome tweeters

Some people just don't like metal domes...I'm one of them - my Memphis MYSNCs have metal domes that are manageable with EQing, but there's nothing quite like a smooth silk dome...

Hi spsfahy,

A tweeter series resistor is a must with this one, otherwise the impedance will drop near zero at high frequencies.

The capacitor should not be put across the amp.

As mentioned above this is not the way to go, things need to be done properly.....

 

[Clipped]

just change the capacitor or cut the wire too it...there will be no drastic effects...ive been doing it for years...

just make sure its atleats 50volts...

or just put a piece of cloth over it...

 

[junglejuice]

All that does is change the xover frequency of the tweeter so unless the harshness occurs at the lower end of the frequency range of the tweeter I doubt that this would change much.....

 

[Clipped]

yes, that is where the harshness usually occurs.

ive never met a tweeter that was harsh at extremely high frequencies,

commercial tweeters in 6x9s simply cant play those frequencies well.
