The Harmony Audio Kicker L7T12 bundle is designed for car audio enthusiasts who want deep bass from a shallow-mount 12-inch subwoofer setup. It includes two square-shaped subwoofers and a powerful 1600-watt Class D amplifier, making it suitable for users seeking strong bass performance without needing a very deep enclosure space. Its frequency response starts at 25 Hz, which means it can reproduce very low bass notes effectively.
