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.
