The Tumult. Since its inception it has been the pinnacle of subwoofers. And the latest incarnation continues that heritage. Simply put, nothing compares to the Tumult. Available in 12", 15", and 18" sizes with dual 4 and dual 2 Ohm voice coil options. The highest performance, world-class sound quality with our patent-pending XBL2 TM motor, amazing build quality. The ultimate subwoofer.

Each Tumult subwoofer features a cast 12 spoke aluminum basket. Dual stacked magnet slugs. All steel cut from ultra-low carbon 1008 grade (not 1012 or 12L14 like most other manufacturers use). Custom wound 3" diameter 4 layer copper voice coil using an aluminum former. Treated thick paper cone with matching dustcap. Heavy foam surround. Rubber mounting gasket. And legendary Adire engineering throughout.

If you want the best, look no further. Tumult.
