Polk Audio Atrium Sub100 - 200W Outdoor Garden Subwoofer - Grey

The Polk Audio Atrium Sub100 is a compact yet powerful outdoor-rated subwoofer, designed to add a level of depth and bass to your outdoors sound system. Perfect for summer get-togethers and BBQs, or for a relaxing afternoon chill in the garden.

Sound Quality

The Polk Audio Atrium Sub100 features a powerful 200W downward-firing woofer, capable of delivering chest-pounding bass perfect for any outdoor party. At lower volumes, it offers a nice warm depth which complements existing satellite or garden speakers for a well-rounded, full-range audio listening experience.

Dual 2-inch voice coil design reproduces bass from both stereo channels, producing more power in the lower frequencies with the help of Capacitive Coupling Technology.

The Sub100 is also acoustically matched with the SAT300 series. When paired with these, you get a highly detailed great-sounding garden audio system to make any neighbour jealous.

Build & Weather Resistance

The Atrium Sub100 is built to withstand any weather condition, thanks to a hard-wearing resin enclosure and IPX66 rating. The grille is made from aluminium and is coated to eliminate the chance of rust.

Included with the Sub100 is an IP68 junction box used to connect the subwoofer cable to the amplifier or other speakers, and can be buried in the ground for a cleaner install. 

Also included is 1 metre Cl3 rated 4-core direct burial pigtail cable, and an eye-bolt security anchor & screw-down points for added stability and security.

The Sub100 enclosure may be painted to match your landscape design, the colour-impregnated resin will never fade and naturally blends in with your outdoor seating - even use it as a plant stand or pedestal table
