Jerrycans are beautiful. Their shape is functional and iconic.
With the price of the fuel being so high, you can't afford to have a leak in your container. If it's the case, here is a simple idea that could interest you. Walking home a few days ago, I found an old set of speakers in my neighboor's trash can. (You know, these brown boxes that nobody uses anymore because today's technology offers much better sound quality.) I didn't know if they worked but I still took them. I smashed the case with a hammer (NOT the best way to get inside), and I unscrewed the speakers from the box.
Warning for music purists: The sound coming out from these speakers won't be HD quality... Jerrycans sound like Jerrycans. It's more a kind of party accessory.

Also my dad has a metal jerrycan that he won't use because it's not easy to pour gas out of it. I'll see if I can have it to make a speaker.
but i searhed on net that there are proper calculations for bass hole and the base pipe length?
so we cant change the size of the nozel have u calculated it ??
if yes then what is the name of your software any link to its download?
The sound isn't amazing but their is not as much vibration that I tought there would be. The use of jerrycan is more for the style than for the sound quality. I usually plug them with an other set of speakers (more compact).
(They're the yellow ones. Red is for gasoline and blue for kerosene.)
I have built several pairs. The last pair of metal, a former Army 20L gas cans. Worn, rusty and stamped with the Swedish military's "three crowns".
You can get the can significantly stiffer with metal bands and lots of heat glue on the inside. The band will stand on end, like a beam. The trick is to preheat the container before you glue, with a real heat gun.
My friends who are audiophiles believe the sound is really good and the girls likes the rough design. Cost 300usd.
There is a trick to get deeper bass. Only deeper bass, no more sound. But deep bass is also the thing that says "come here now it's party!" If you choose the elements well and assembles them as "airtight serial connected" you can create the real "club sound". You feel it in your stomach.
To get good volume outdoors you need to actually get a lot of power. It surprised me a lot. Often its enough with 3-5 watts indoors to get evicted from the apartment, but out on a field you often need a lot more lika 30-50 watts.
Lead-acid batteries are heavy. Lipo is expensive and difficult to monitor. If you do not monitor lipo it is easy to be deep discharged them and it is NOT GOOD!

«Speakers sound surprisingly great too!»
