The Polk Audio Atrium SUB100: Grey Sub offers a way to add deep bass to your outdoor audio setup. It uses a 10-inch driver, which is a big speaker part that moves air to create the low sounds. This driver is designed for a long throw, meaning it can move a lot of air. This helps produce richer, more powerful bass. The subwoofer is down-firing, so the sound comes out the bottom. This design can help spread the bass evenly. It’s built to handle outdoor conditions, so rain or sun shouldn’t cause problems. This is important for outdoor equipment. It helps reduce clutter because you can place it out of the way. It is a good choice for people who want more bass in their outdoor listening experience.
When thinking about sound quality, the Polk Atrium SUB100: Grey Sub performs well for its intended use. It adds a noticeable depth to music and movies. The bass isn’t overpowering, but it is definitely present. The all-weather durability is a key feature. It means you don’t have to worry about it getting damaged by the elements. The grey color blends in with many outdoor settings. The construção feels solid, suggesting it will last. While I can’t speak to the long term sustainability of all the products used in the subwoofer’s build, the materials used for the exterior are clearly made to last. The treatment given to the outer casing is effective.
For those considering adding a subwoofer to their outdoor sound system, the Polk Atrium SUB100: Grey Sub is a solid option. It provides good bass without being too expensive. It’s designed to withstand the outdoors, which is a big plus. It’s easy to set up and use. It helps clean up the outdoor audio setup by taking away the need for large speakers.
