SLAPS-M8

The SLAPS-M8 passive radiator boasts impressive performance with extended excursion capability. It also features a very rational price due to the annular stamped steel chassis. 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 that they can be integrated into virtually any sub/cabinet combination.

The SLAPS-M8 passive radiator is a patented type of passive device that significantly increases subwoofer efficiency and ability for ultra low frequency reproduction. SLAPS is short for Symmetrically Loaded Audio Passive System. As the name indicates, SLAPS is built symmetrically which distinguishes it from traditional passive devices. SLAPS technology integrates identical components in its suspension design resulting in identical stoke regardless of forwards or backwards motion. The high efficiency and performance is a result of the pneumatic coupling between SLAPS and an active driver.
