Why don’t bubbles have corners?

Simple, really. It’s all about the best way of

enveloping a given volume of gas. Bubbles always

adopt the form with the least possible surface area

- which is always a sphere (and never a cube or 

a pyramid or anything else with corners). It’s the

most stable form there is, too. The air pressure

inside a bubble pushes outwards, equally in all

directions, but surface tension balances the air

pressure out and holds the bubble together evenly,

all the way around. No corners, no straight lines.

Just a lovely, round bubble. Beautiful.

When we decided to create a new, powerful, com-

pact subwoofer for use in home theatre or two-

channel set-ups, we weren’t going to contradict

nature. We wanted to deliver big bass from a small

speaker, as purely and naturally as possible. We

needed something that could withstand the huge

variations in air pressure that very low frequency

sound generates. We needed to design a pressure

vessel that wouldn’t do a wobbly at high volumes. 

So instead of making a box, we made a bubble.
