18-Inch Subwoofers — Built for Serious Output

An 18-inch subwoofer isn't for the faint of heart — it's for builders who want to feel bass as much as hear it. With massive cone area and long-excursion motor assemblies, 18" drivers are engineered to produce extreme low-frequency output in large ported or bandpass enclosures. If you're building a wall, a van, or a dedicated SPL vehicle, this is your size.

• Massive cone area for extreme low-frequency displacement
• Designed for large ported and bandpass enclosures
• High power handling for amplifier-heavy builds
• Single and dual voice coil options available
• Brands include American Bass, B2 Audio, DC Audio, Resilient Sounds, and more
