Earthquake SLAPS are Tunable Passive Radiators that provide additional bass, without additional amplifier power or enclosure volume.

Designed to perfectly complement all good quality long-throw woofers on the market. SLAPS add up to +6dB of bass compared to regular sealed and ported enclosures. The benefit of them being user tunable is they can be integrated into virtually any sub/ cabinet combination.

Key Installation Benefits:

• Installs just like a subwoofer
• Slim-mount design is only 3-inches deep
• No increase over existing sealed subwoofer enclosure sizes
• Easy tuning for quick adjustments
