American Bass VFL Comp Signature Series 18" Subwoofer

Delivering 5,000W RMS (10,000W max) from a single 18-inch driver, the American Bass VFL Comp Signature Series Subwoofer is built for SPL-focused builds where loud, precise bass matters.

• RMS POWER: 5,000W — continuous power handling defines how long the sub can sustain high output without thermal limiting, important for steady competition-style bass passages.
• MAX POWER: 10,000W — peak power capability used during transient bass hits, contributing to dynamic slam without overdriving the voice coil.
• IMPEDANCE (OHMS): DVC 1/2 Ohm — dual voice coils configured for a low-impedance load, enabling high-current amplifier pairing in demanding setups.
• MOUNTING DEPTH (IN): 11” — total depth of the driver requires a correspondingly deep mounting location in the vehicle or enclosure.
• CUTOUT SIZE (IN): 17” — opening diameter needed for installation, guiding enclosure fabrication.
• MAGNET SIZE (OZ): 500oz — large magnet provides strong control over voice-coil motion and helps manage heat during extended high-output play.
• VOICE COIL SIZE: 4” — a large-diameter coil supports higher power handling and improved cooling for sustained performance.
• CONE: carbon fiber paperback cone — rigid construction enhances transient response and reduces cone deformation under high excursion.
• SIZE: 18” — indicates the driver diameter, contributing to bass output through increased surface area.

In a real car audio build, this subwoofer is designed for high-current, low-impedance systems that demand serious SPL. The combination of a 500oz magnet, 4" voice coil, and carbon fiber cone supports strong control and linear response under extreme power, while the 11" mounting depth and 17" cutout define a need for substantial enclosure fabrication. This driver is suited to competition-grade installations where maximizing output and maintaining clarity at high levels are priorities.
