The SoundQubed HDX3-12 Series Subwoofers are the ultimate heavy-duty subwoofers designed for competition-level performance. Made in the USA, these subwoofers feature a monstrous dual voice coil that delivers a beefy sound like no other.

Available in 12 inch, 15 inch, and 18 inch sizes, the HDX3 series can handle an impressive 1500 Watts RMS power and 4500 Watts Peak power for those intense burps that will make your vehicle shake.

One of the standout features of the HDX3 subwoofers is their motor. With a thick top plate, high motor force, and a tight gap, these subwoofers are designed for high-efficiency speaker performance. The taller 4-spoke cast aluminum frame allows for a larger diameter spider, which results in lower tuning and greater accuracy. The larger diameter spider also has a new roll profile that enables low F's without sacrificing power handling or control.

The HDX3 subwoofers also feature a taller and wider surround, which allows for even more precise excursion. The new pulp-blend cones are not only stronger than previous designs but also lighter, ensuring a powerful and accurate sound.

Improvements over the HDC series subwoofers include a thicker and more robust aluminum former, as well as black anodizing for added durability. These subwoofers are designed to handle increased cooling abilities, enhanced performance, and a longer lifespan for your enjoyment.

With a 3" voice coil and a cast frame, the HDX3 subwoofers deliver exceptional sound quality and power. Whether you're looking to upgrade your car's audio system or compete in high-level competitions, the SoundQubed HDX3-12 Series Subwoofers are the perfect choice.
