Built-In Power. Full-Spectrum Punch. Meet the TUBE12VA.

For those who demand more than bass — who crave total control, clean output, and built-in power — the TUBE12VA is your new low-end weapon. This active bass tube fuses high-performance audio engineering with Cadence’s signature bold design, bringing immersive sound and seamless integration to any vehicle.

• Amplified Precision, Ready to Rock: Engineered with a Class D amplifier built right in, the TUBE12VA delivers 300 watts RMS of pure bass energy, eliminating the need for an external amp while ensuring efficient, low-distortion output.
• 12″ Driver with Serious Muscle: At its core sits a 12-inch subwoofer with a 2” high-temperature voice coil, capable of handling up to 700 watts peak — pushing rich, commanding lows that rumble through your entire cabin.
• Tuned Ported Tube Design: The cylindrical, bass-reflex enclosure is acoustically optimized to maximize airflow and deliver smooth, powerful response across the 32Hz–500Hz range.
• Premium Sound Components: The sub features a laminated black paper cone paired with a resilient butyl rubber surround — combining warmth, accuracy, and long-term reliability under pressure.
• Control at Your Fingertips: The integrated amp panel includes a 30–150Hz low pass filter, RCA inputs, and a 25A fuse, giving you control over crossover tuning and clean signal input from any aftermarket source unit.
• Signature Tube Series Styling: Wrapped in black automotive-grade carpet with high-contrast Cadence orange embroidery, the TUBE12VA stands out with rugged elegance. A metal mesh grille guards the sub, while the vibrant orange port bezel frames the rear amp panel like a badge of power.
• Compact Yet Commanding: Sized at 26″ wide and 13.1″ deep and high (660mm x 333mm x 333mm), the enclosure is easy to install in tight spaces — but once it’s in, you’ll hear (and feel) the difference immediately.

With the TUBE12VA, you get more than bass — you get a fully integrated performance machine that hits hard, looks bold, and installs with ease. From the first beat to the final drop, it’s all in the tube.
