Performance Subwoofer provides enough air to create the thumping bass we all deserve, we’ve added a passive radiator to our all-new Performance Series of subwoofers. This passive diaphragm reacts to the changing air pressure within the cabinet, virtually doubling your woofer’s ability to create sound without drawing additional power. As a result, even smaller cabinets like these can create impactful low frequencies. Our brushed hybrid finish is durable and easy on the eyes. This thick, textured wrap looks and feels much more luxurious than the standard vinyl finishes you might see in other subwoofers at this price point.
