The big driver gets better. The mighty Maelstrom is now a complete line of subs. Available in 12", 15", and 18" sizes with dual 4 and dual 2 Ohm voice coil options. Massive output with deep extension. But plenty of finesse and resolution for delicate performance.

Each Maelstrom subwoofer features a cast 4 spoke (6 spoke on the 18" driver) aluminum basket. Massive triple 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.
