With a peak power of 1200W and an RMS of 400W, these subwoofers are capable of delivering strong and consistent sound. The 2-ohm impedance and single 2-inch voice coils contribute to efficient power handling and deeper bass output.

The frequency range of 37-150 Hz, while not the broadest, covers the essential low-end frequencies for most music genres, providing a satisfying audio experience for everyday listeners.

The inclusion of rubber surrounds and polypropylene cones further enhances the longevity and sound quality by reducing distortion and allowing for better woofer control.

However, the 13.5-inch mounting depth may require careful consideration of space during installation in certain vehicles. Being wired subwoofers, they require proper connectivity setup, which might be a bit complex for users unfamiliar with car audio installations. Additionally, the product is on the heavier side at 30 pounds, which could be a factor for some users considering ease of handling and installation. Despite these minor drawbacks, the MTX Terminator Dual 12-Inch Subwoofers offer significant power and quality for car audio enthusiasts looking for a substantial bass boost in their vehicle sound systems.

This is complemented by the sensitivity rating of 97 dB, which means it can produce loud sounds efficiently. The frequency range of 15Hz to 20kHz ensures that it covers a wide range of bass frequencies, capturing both very low and high ends effectively.

The 4-ohm impedance makes it compatible with most car audio systems, and the dual voice coils provide flexibility in wiring options. The quasi transmission line cabinet design and 15% angled enclosure are designed to optimize bass alignment within the vehicle, enhancing sound quality. Additionally, the package includes a matching mono block amplifier and a comprehensive amp kit, making the installation more straightforward and convenient.

However, there are a few drawbacks to consider. At 53 pounds, the unit is quite heavy, which might pose challenges for some installations. Despite its robust build, it lacks waterproofing, so it’s not ideal for vehicles exposed to outdoor elements. Also, the product dimensions (5"D x 16"W x 5"H) should be checked against the available space in the car to ensure a proper fit. The subwoofer does not include an MP3 player, but it is compatible with smartphones and other devices via RCA connectivity. In summary, the Rockville RV12.2B is a powerful and efficient subwoofer system suitable for users seeking to significantly improve their car audio experience with strong bass performance.
