Earthquake - SLAPS-12 - 12" Tuned Subwoofer Radiator (Single)

Designed for system builders and subwoofer enthusiasts seeking to unlock deeper, cleaner bass from compact enclosures, the Earthquake SLAPS-12 12" Tuned Subwoofer Radiator offers an innovative solution for extending low-frequency response without the limitations of ported designs. Perfect for DIY subwoofer builds, passive radiator upgrades, or tight-space installs, the SLAPS-12 dramatically improves bass performance by enabling greater cone excursion and tighter control—delivering punch, depth, and musicality in equal measure.

The SLAPS (Symmetrically Loaded Audio Passive System) technology allows the diaphragm to move in both directions, unlike traditional passive radiators that only react to one side of the driver’s motion. This dual-movement design results in better excursion, increased output, and reduced distortion. Tuned for optimal performance in enclosures matched to Earthquake’s high-excursion drivers or other compatible woofers, the SLAPS-12 enables cabinet designs to achieve the deep bass extension of a ported system without port noise or chuffing. Its non-pressurized behavior also means it works efficiently in small or sealed enclosures.

Whether enhancing a high-end home theater build or upgrading a sealed box subwoofer, the SLAPS-12 transforms low-end dynamics—producing clean, tight, and forceful bass that’s felt as much as heard. It’s an advanced tool for those who demand more from their low-frequency systems.
