Earthquake - SLAPS-15-V2 - 15" Passive Subwoofer Radiator (Single)

Built for custom subwoofer systems and demanding low-frequency applications, the Earthquake SLAPS-15-V2 15" Passive Subwoofer Radiator offers a powerful solution for extending bass depth and output in sealed or compact enclosures. Ideal for home theater builders, high-performance subwoofer upgrades, and OEM replacements, the SLAPS-15-V2 delivers greater excursion and more accurate bass than traditional passive radiators. It enables deep, tight, and controlled low-end performance without the need for a bulky port, making it a go-to choice for space-conscious designs that don't compromise on sound.

The SLAPS (Symmetrically Loaded Audio Passive System) design features a dual-suspension, dual-movement configuration that allows the diaphragm to respond symmetrically to the driver's energy. This results in significantly improved control, increased air displacement, and extended low-frequency reach, all while reducing port-related noise and distortion. The V2 version brings upgraded materials and enhanced compliance, allowing it to pair seamlessly with modern high-excursion subwoofer drivers. Its massive surface area and free-moving mass are tuned for maximum output and efficiency when integrated into sealed or slot-loaded cabinets.

For builders and audio pros seeking maximum bass performance in a refined form, the SLAPS-15-V2 delivers serious low-frequency impact. It supports cinematic LFE demands and musical precision alike, offering visceral bass that feels clean and immediate—without the footprint or drawbacks of traditional ported designs.
