A speaker in a coke can - could it be? (1 Viewer)

[Javier_Huerta]

As I was looking at this Coke can, I realized I could built a pretty weird speaker out of it (don't ask me how I came to realize this fact - I guess the meeting I was in was too boring).

What do you think? Is it possible? I have looked for little woofers in Parts Express (I guess I'd need a 2" driver) but I can't find any.

It'd look very cool. Now imagine it with a small tweeter on top.

Would the coke can make it sound incredibly harsh and tiny, as the thin aluminum would reflect and boucne alot of the sound. A coke can isn't exactly a dead enclosure. But what do I know.

 

[TimForman]

Maybe if you could get hold of the aluminum cone driver that
Sharper Image uses in some of their devices.

 

[Javier_Huerta]

Cam, what if the inside of the Coke can was sprayed with sound deadener, or had foam in it?

The reasion I'm asking is, Sonotubes are often used for subwoofers. A Coke can seems to be an excellent enclosure for a small speaker. I can imagine it, with a couple of small stands, painted with a metallic lacquer and and clearcoat, with a small tweeter on top.

I guess I'll have to find a small enough driver for my tests.

 

[Mark Fitzsimmons]

Why even mess with a tweeter? I'm sure you could get a full range 2" driver.

 

[Javier_Huerta]

A tweeter would make the thing like an R. Crumb cartoon of a B&W Nautilus, I think

I'll try it. I mean, how much can a decent 2" driver cost?

Crush a coke can in your hand. Now try crushing a sonotube. I think it should be obvious why a coke can would be a waste of effort.

Well, yeah... but the Coke can wouldn't be dealing with a Tempest, or a Maelstrom. It'd be home to a nice little 2" driver...

How cute. I could build mini-subs and sell them with a note saying "My dad is a Tumult"

 

[Brian Bunge]

If you want to play around with them you could always try some of these 2" drivers on clearance at Parts Express.

I wouldn't expect too much from them though. And definitely not in a Coke can.

 

[StevieP]

I guess you could put a Bose driver in it (probably sound about the same )

That isn't the point. The point was that one creates a rigid enclosure that is not likely to add coloration to the sound produced. The other does not do this. I'd much rather use PVC pipe like these.

I would just use a piece of 2" PVC and cut out a 2" piece
of 3/4" MDF and hot glue it inside the tube on the backside
add some binding posts and put a deflex pad inside and a
simple lowpass capacitor and run a decent full range driver
and woolah bose killer.. (It doesn't take much to kill bose)

How about a coffee can...

Started on a pair using sewer pipe but haven't finished.

I'm still thinking aluminum can, aluminum driver. Say it with me, "aluminum can, aluminum driver".

 

[MichaelAngelo]

Save up those cardboard liners in the TP for an array

 

[Frank Carter]

Would you like peanut butter with your "subwoofer"?

 

[JoelTW]

hahaha

 

[Brett DiMichele]

I say someone should make a sub out of one of those Phart
Pipes you see on all the Hondas these days.. Heck most of em
are at least 7" OD.....

 

[Randall Duncan]

Ooh!! Creative audio! I think I'm gonna get me some PVC pipe
and put together some speakers using those little 2'' speakers
from Parts Express... Because I have 24 of them!
