The PUMP-12 was designed to add more bass output to subwoofer systems without additional amplifier power or enclosure volume. This passive radiator module features a horn loaded neck and an anti-rocking dual suspension system. They increase your subwoofer’s SPL up to +6dB compared to typical sealed/ported enclosures and will compliment all good quality long-throw woofers on the market today. They can also be integrated into virtually any customized enclosure/cabinet combination if you prefer to build your own PUMPed enclosure.
