Features and installation details

Bass Xtreme Series 12" DVC Subwoofer

Built for Aggressive Bass, Precision Performance, and Versatility

The Soundstream BXW-124 subwoofer is your go-to solution for hard-hitting bass that doesn’t compromise on precision or durability. Designed to complement Bass Xtreme amplifiers, this 12-inch subwoofer blends affordability with high-performance features typically found in much pricier models.

Engineered with a 4-layer dual 4-ohm voice coil, the BXW-124 delivers flexible wiring configurations to suit various system setups. Whether you're aiming for a 2-ohm or 8-ohm final load, the dual voice coil (DVC) structure gives you the freedom to customize your system while maximizing power handling.

Durable Components for Heavy Hitting Audio

The spruce paper cone is lightweight yet rigid, allowing it to produce clean, accurate bass even during aggressive playback. Paired with a polyether foam surround, the cone remains centered and controlled, maintaining excursion stability during deep hits. The extra-long cone excursion enhances low-frequency depth and allows the sub to hit those crucial bass notes without distortion.

The 2.5-inch 4-layer high-temperature voice coil handles thermal stress under prolonged use, maintaining structural integrity during high SPL sessions. Built for both sealed enclosures and ported boxes, the BXW-124 adapts to a wide range of installation needs, from factory upgrades to full-scale custom builds.

Seamless Integration with Existing Systems

With 87.5 dB efficiency, this subwoofer is tuned for optimal output without requiring massive power to perform. It works excellently in moderate setups, making it a reliable replacement subwoofer or a solid addition to your current configuration. The sub's mechanical structure and impedance flexibility ensure it meshes well with most car audio amplifiers, especially Class D mono and multi-channel amps.

Compatibility Note

If you’re wiring x`this dual 4-ohm subwoofer for a lower impedance load (e.g., 2-ohm), be sure to verify that your amplifier is rated for that resistance. Refer to a subwoofer wiring diagram to avoid damaging your system components.
