Speaker Fabrication
Posted by Anonymous on Monday, September 20, 2004 9:41 PM
Hi there. I view modeling as a way of creating something that otherwise I couldn't have...it is my curb to wanting every sweet car I see go down the street, fully customized, and the way I want it: that is how I am approaching this new sport. My question is to you; a see a few speakers and speaker grills for sale as interior details...but the more I think about it, I'm sure some better ones could be made, with some of those cool ways of mounting them that they do in 1:1 cars (Is that the correct terminology) with their fiberglass showcases pretty much. So...of course I'm going to approach it with time, but I figured I'd ask now; anyone have better ideas of making speakers yourself? Maybe out of that styrene stuff or something?
Whatever comes to your mind, I thank you in advance.

this i havent tried yet but have given some thought too as well the only thing that i can figure is to make the fiberglass box or showcase outa bondo... thi is not the best thing for that and it will probably be very difficult to do ... thus in my lazyness i havent tried.. in any matter that is the only rout that i can come up with however all ideas as u suggest will be entertained

Try using Styrofoam; the first that comes to my mind is the hard green stuff that florists use to create flower arrangements from fake flowers… It’s green and hard. This can be cut, sanded and filed smooth. There are other types of foam that could be substituted.

As an alternative, how about Balsa wood... It is cheap enough and can be shaped to suit

Those are some great ideas for creating the odd speaker boxes that they make. but I was also wondering how one could make some speakers (with or without a grill - some of those wild new ones are protected with a few coat hangers; otherwise I'd just use some mesh or something). As far as the box conversation goes, how would you prepare the box to be painted? put a coat of some putty on or something?

I'd coat the box with putty or spray sealer before painting. For making a speaker I’d decide what type I want, there are so many shapes and sizes it's not even funny...

For a round speaker you could try hitting a hobby shop or dollar store and looking for things like stick on google eyes, take them apart and flip the “dome” upside down so that it looks like a bowl, then get a smaller eye and stick it in the "bowl" but right side up. That would make the general shape of a speaker. Mind you, that's just off the top of my head, im sure there are WAY better ideas and way better items that you could use.

You could use a lathe to spin your own speakers from balsa, or use a drill as a make-sift lathe. Once you get the shape right you could learn how to make molds with it.

Seems to me for the actual speakers it would be just as easy and possibly as cheap to order something like this

or this


from http://www.bestresin.com/index.html

As far as the unusual shaped boxes go. The 1:1 guys make a wooden form with supports and so on and then laying fiberglas cloth over them.
It never hurts to search the internet and get info in how the 1:1 is made

The 1:1 guys don't use fiberglas cloth on the free-form boxes and doorpanels they make. Instead, they use a type of clothing material that stretches because fiberglas cloth doesn't stretch. I learned about this technique by watching OVERHAULING on Cable TV.Smile

Fibergalss cloth does have some stretch to it, and it is used. Cabe TV is not the only source for info. The cloth is then covered in polyester resin ( fiberglass)

Here's a trick I have used for speakers. I use speakers. Real speakers. I use the little speakers from dollar store headphones. I just tare them apart any ues them. You can even make them work and get real 1/25th scale sounds.

Another product that may be used is polymer clay. I have never used it for this purpose yet, but plan to try it out. If anyone else does before me let me know how it works.

Polymer clay is easy to work with and hardens when you bake it. (Dont bake it with any plastic parts though) Once it is baked it can be sanded, cut, glued painted, anything you need to do with it. It is very light weight too.

I think it would work well because you can shape a chunk of it and fit it in the car where you want it to go so that it takes the shape of the area it will be glued. Remove it from the car then bake it so that it retains the shape.

for the fiberglass box you could actually duplicate the same process on a smaller scale pretty easily.

Radioshack stocks grill mesh in the speaker section...It's thin enough to keep the bulk down. When i make the 1:1 size i either use grill mesh,old cotton t shirts or fleece from a fabric store... If you'd like some other tips or just need some help with it email me

x0_scorch_0x@hotmail.com

I might try one for myself on my next project..

My way of making scale speakers for cars etc…
Watch the pictures in sequence…

First work out what size speaker you would like, I made mine 1cm across.
1st .Coil the wire around a knife handle of appropriate size.

Take it off and snip into individual circles.

Glue the circle together.

Set your compass for a 12mm diameter circle and mark your foil

Then cut out the circles. The foil I used was from a tomato puree tube.
Take your knife and from the middle to one edge make a cut.

Form into a cone and glue.

Now glue the wire circle to the top of the cone.



While glue sets up, take a piece of round sprue and gently melt one end into a small dome.
Snip it off just underneath it.

Now take the cones and clean up the edges with a small file.

Glue the sprue dome into the middle of the cone.

Paint and either leave open or cover, I used an old pop sock like a stocking from the wife to cover mine.

Voila sit back and enjoy the sound.
I used Tamiya Nato black xf69 and x11 chrome silver paint.

i don't know if anyone thought of it, or if it would work because i never tried. but i thought of taking the bubble part of those wiggly eye things you can get at the craft store and taking the back off, and using a larger one for the speaker, and a smaller one for the center cone thing or whatever. if that is a good idea let me know because i was thinking of trying it.

Don't know how it is over at your side of the pond, but here 20-packs of headache pills (and other too) comes with the pills packed separately on a vacuum-formed plastic board with small domes for each pill, each board covered with a thin alu foil. These small domes, or cups, could be a starting point for speakers. Don't know if this meant any sense to you, but....

um is it just me or is anyone else having trouble seeing hawkone's pics? i don't even see red Xs, just white. Anyhow, on the topic of speakers, i'd have to agree with dag, just get em from BestResin. I haven't purchased anything from them, but it looks like there is some real high quality stuff there. to make the boxes, I would probably use the florist foam and coat it with a layer of putty, sand it, and paint it

Hawkone's post is only a day old. I suspect there should be a link to the page with the photos.

For what these resin casters are charging for a set of speakers (even the Pegasus stuff, which is the most expensive I have see), I would save myself the trouble of making them. It seems like an awful lot of work to get them looking realistic.

LOL! yeah I was looking at the join date. DUH!

I have to agree about the time and effort of making realistic units vs. just buying them

That's the very site I was thinking of when I mentioned the low cost of speakers. If anybody has used these guys, what did you think of the quality and the company?

For speaker cones, use a compass and cut progressively larger "washers", then stack and glue them; paint 'em flat black

BTW, if you're dealing in 1/25th scale, a 1 cm speaker would be 25.4" in 1:1 and that seems a tad large.

There is another place that sells them. http://www.hoppinhydros.com They have speakers, speaker boxes, boomer tubes and speakers, and amps batteries and stuff like that.

Hope this will help

Um, are you sure? I thought 1/25 was 1 scale inch for every 25 real inches, that would mean a 1 inch diameter speaker is about 25 inches across. What is the largest you can get speakers real speakers? I've seen up to 16"

1mm = approximately 1" in scale, so a 1cm speaker would be 10" in full scale. daklunk you are correct, 1" (or 25-ish mm) would be 25 inches across.

good idea, you could also create a negative shape and then using rasin casting and made multipul resin casts
