TR12P Truck Box with 12" SLAPS Passive Radiator and 12" Shallow Subwoofer Enclosure

Designed for truck owners who refuse to sacrifice bass for cargo space, this prefab enclosure combines Earthquake Sound's SWS-12X shallow-mount subwoofer with our SLAPS-M12 V3 passive radiator to deliver deep, powerful low-frequency performance from an ultra-compact footprint. The SWS-12X’s patented shallow design produces impressive excursion and output while requiring minimal mounting depth, making it ideal for under-seat and space-constrained truck applications. Paired with the tunable SLAPS-M12 V3 passive radiator, the system extends low-frequency response and increases bass output without requiring a larger enclosure or additional amplifier power. The result is clean, hard-hitting bass with exceptional efficiency, musical accuracy, and low-end extension that outperforms traditional sealed truck boxes. Built for modern pickups and daily drivers, this enclosure offers premium sound quality, maximum space savings, and the legendary performance Earthquake Sound is known for.
