Polk Audio Banner


The Polk Audio Atrium SAT300 is a compact full-range speaker designed to be placed in a garden or outdoor area. It can be planted into the ground, for example, the lawn or flowerbed, and the natural brown/green colour will ensure it's as unnoticeable as can be.

It can also be hung from a ceiling, eave or beam which may be better in a patio or seating area, and if that isn't an option it can simply be placed on the included stand.


Why have an In-ground Speaker?

The benefit of this system over a traditional rock or cabinet speaker, is that all sound is directed inwards with very little lost to the surrounding area. This ensures you get the full volume and frequency range of the speakers, with very little leaking behind into the neighbour's garden. 

With a number of these speakers placed around the garden, it means there is no loss of volume and quality wherever you stand.


Build & Sound Quality

The Polk Audio Atrium SAT300 is made of high-quality materials to ensure minimal damage from weather and other sources. A shock-absorbing gasket can withstand whacks from lawnmowers and other lawn equipment, and the included 1 metre Cl3-rated direct burial pigtail cable eliminates exposed wiring. There is also a metal security plate to prevent theft as it keeps the SAT300s planted safely in your garden.

At 100W power speaker, there is plenty of power to fill your garden with sound. The SAT300 features a separate 3.5" driver and 0.75" tweeter with a built-in crossover, and thanks to Dynamic Balance Driver Technology this compact size provides a mighty punch. This is also enhanced by the built-in bass performance technology, offering extended depth.


Weather Resistance

The Polk Audio Atrium SAT300 is built to survive in the elements. With an IPX66 rating, it's comprised of a mineral-filled polypropylene housing, 1mm aluminium grille & stainless steel hardware, ensuring it will handle any weather.
