Versatile Wiring, Tight Bass, Maximum Performance

Dual 4-ohm voice coils provide flexible wiring options, making it easy to match your amplifier for maximum power output and efficiency—ideal for bridging or parallel setups. Wrap-around gasketing ensures a secure, airtight fit in any enclosure, reducing unwanted air leaks for consistent, accurate bass. Patented ribbed corners in the unique square sub design minimize distortion at high excursions, keeping your bass clean, tight, and powerful even at maximum output.

Engineered for Precision and Power

The injection-molded SoloKon woofer cone combines strength and lightness to minimize flex and deliver punchy, accurate low frequencies. 360° SoloKon back bracing reinforces the entire cone structure, preventing distortion and deformation even under high power. The UniPlate back plate and pole piece, paired with a bumped back plate, create a robust motor system that optimizes heat dissipation, ensuring consistent, reliable performance under heavy loads.

Durable, Powerful, and Precise Bass

Thick tinsel leads are extra-strong and heat-resistant, maintaining signal integrity even under high excursion and extended use. The large ceramic magnet generates a powerful magnetic field, driving the cone for strong, deep, and responsive bass. Housed in a steel basket with a spoke design, this subwoofer remains rigid and vibration-resistant, delivering tighter, cleaner bass and long-term durability.
