Bigger Volume
Maximum Airflow Port Tube - unique flared design at both ends optimizes airflow to generate maximum sound. 

Deeper Bass
Balanced Dual Air Chambers - tuned specifically for its Bandpass enclosure and properly balanced to enhance performance of 10” injected poly driver for deep, rumbling bass. 

Greater Sound Dispersion 
Exclusive Soft Curve Cap - projects sound throughout the surrounding area rather than sending it back into the ground like other underground subs. 2,500+ square foot omnidirectional sound. 

Smaller Footprint 
Less Than 19” Long - Enjoy big, booming sound with the smallest landscape footprint in the industry.


Tech Tip: Before burying the sub, put gravel at the bottom of the hole for drainage, leveling and to help prevent freezing.
