Re: Can you paint speakers?

I'm sure an audio purist would shudder with horror.

After all, a layer of paint would add to the mass of the speaker cone. This makes it harder for the electromagnet to move it. This distorts the sound, since the design of the speaker and crossover take into account how the speaker sounds with its current mass.

On the other hand, the mass of a very thin layer of sprayed-on paint is miniscule.

I wouldn't suggest applying a layer of latex with a paintbrush, though.

I could not have said it any better..

Crossover-----Switching sides...lol
Distortion-----Something the wife does...lol
Miniscule.........Does size really matter?...lol ;>)

Hope the Easter Bunny lays golder eggs for all...

Have A Great Day!!

Re: Can you paint speakers?

I think there is a huge potential for disaster.. besides the added weight, the paint is going to affect the rigidity of the cone and therefore the way it moves.

Of course, I've never done it, so maybe it'd be fine, but I would be more than just a little squemish doing this to anything but my junk speakers.

Re: Can you paint speakers?

I have seen airbrushing on subwoofers a lot in car audio and i would not hesitate to paint a subwoofer driver where the mms is more often than not fairly high to begin with but i would not be painting the cones of midrange speakers or a tweeter

You are "The man".....

An airbrush would supply such a light coat that it would not effect any movement one could hear without puting a scope on the speaker being played....but I guess one could over air brush to an extreme if so desired..

Have A Great Day!!

Re: Can you paint speakers?

Your taking a chance of changing the sound, as the paint will also dampen the driver and alter its mass. It may work out in your favor but it's a gamble...and not advisable on a high-end speaker.

Re: Can you paint speakers?

When you paint the cone of a speaker, you will add mass to it and affect the resonant frequency, Q, sensitivity, and upper-frequency rolloffs. If you look at the TS parameters, many of them are changed by mass. Most speaker cones are black, and it will take a lot of paint to cover the surface. The mass increase may be more than you think. If you are building a speaker enclosure you should measure the TS parameters before and after painting and before you design the enclosure. If you already have the enclosure designed, or this is a commercial speaker, I can only warn you that you may de-tune the speaker and spoil the bass response and crossover phasing.

Re: Can you paint speakers?

I'd say if you haven't allready done it then before you do use a cheap driver. I'm not sore if they still do but PE used to carry a product called "wetlook" wich was basically a clear coat for paper based drivers.
On a polypropylene cone i would worry about the paint sticking to it more then it severly changing the parameters so long as you don't spray a whole can on it.

Re: Can you paint speakers?

A ported enclosure has high sensitivity to TS parameter shift. Paint on the cone will cause significant shift. A sealed enclosureis less sensitive, and may tolerate this without noticeable shift of audible performance.

Re: Can you paint speakers?

Thanks for all the replies guy's. I don't intend to paint any speakers but it just was something I had not seen anyone do since back in the day when we would find old speakers in the junk that we would shoot at after painting them red.....I don't think they sounded to good after that. The air brush idea sounds like it would be the best way if anyone ever wanted to try it.
