I have MB Quart speakers currently in my car, RSB 218 Seperates in front and Mobil 160.03 kx coaxials in the rear. As these speakers give out a really bad vibration at certain frequencys when played loud, I am not sure the cause of these vibrations, I was thinking of buying a set of Image Dynamics Chamelions speakers. I wanted to get input on what everyone else thinks on this. Should I keep the Quarts, or should I get the ID. The main advantage I can see from get the ID speakers is I can get them in 2 Ohms and utilize more power from my PPI PC4400 amp. Also if I do get the ID, should I just replace the front speakers or should I replace them all? I want the speakers to sound good together, but I know rear is basicallly used for fill, so I don't know if it is necessary.

 

What do you mean by "vibration"? Are parts of the car vibrating at certain frequencies? That wouldn't be the fault of the speaker.

 

When I say vibration, I mean a hum that is coming from the 6.5" speaker at certain frequencies, and can be reduced or taken away by fiddling with the EQ. When I took it to my installer, they said the speaker may be out of round or something like that. It is slowly becoming worse, which is the reason why I am considering new speakers.

 

Are you sure that it's not the interior door panels? Mine buzz at certain frequencies. It could also be the inner sheet metal panel that the speakers are mounted on.

 

I'll have to check that out. . .I don't really trust my installers all that much. . .I need to check with a place I trust. It didn't used to do it, but things can become loose it should be something I try.
