If you're looking for distinctive-looking speakers, you shouldn't look any further than these ones. They were handmade by an audiophile and are available on Etsy for purchase. However, you could also try and make your own PVC pipe speakers.
However, you could probably try your own hand at making something like this. Although we don't recommend making your own speaker from scratch, you can graft the guts of an existing speaker into some PVC pipes to see what you'll get. This hack kind of works like the IKEA salad bowl speakers.
Still, for handmade speakers, the ones from Ikymagoo aren't that expensive. He's got a bunch of different models available in a few colors. He'll even build you a custom set if that's what you really want. All in all, it's an interesting idea.
