The Atrium Sat30 is aesthetically versatile – you can plant it on the ground, or hang it from its wires. They’re also pretty tough – Polk Audio claims that they can withstand “blows from weed whackers, mowers and other lawn equipment”, thanks to their shock-absorbing gasket.

The Atrium Sat30 can be used without the Sub10, but this big fella is really the one which makes the system shine. It’s a 200-watt subwoofer with a 10″ “Long Throw” Driver.

You can even use it as a stand, as it’s able to support objects up to 200 lbs. The Sub10′s surface is also paintable, so you can easily replace the chestnut brown color.

You can order the Polk Audio Atrium Garden Speaker System at Amazon for $600 (USD). The bundle includes one Sub10 and two Sat30s. You can also buy them separately – the Sat30 sells for $150, while the Sub10 sells for $300.
