Designed to fit in tight spaces, its slim profile with a mounting depth of just 2.625 inches is perfect for under-seat or behind-seat installations in various vehicles. The subwoofer's Glass-Fiber & Mica Reinforced IMPP cone adds rigidity and strength, enhancing sound quality with deep bass that remains clear and dynamic.

With a nominal power of 250 watts and an impedance of 2 ohms, it efficiently pairs with compatible amplifiers, delivering reliable performance. The sensitivity rating of 83 dB is somewhat lower than some competitors, meaning it may require more power to achieve higher volume levels. The single voice coil design simplifies wiring, making installation straightforward.

While the recommended 0.5 cu. ft. sealed enclosure means it’s best suited for specific setups, this might limit flexibility for custom installations. Users who value space efficiency, strong bass performance, and compatibility with Pioneer’s A-series speakers will find this subwoofer a highly suitable choice.
