TEMPEST SUB WOOFERS


The Tempest expands.  Ever popular, the Tempest is now a complete line of drivers.  Available in 10", 12", and 15" sizes with dual 4 and dual 8 Ohm voice coil options, perfectly suited for home audio applications.  Very high performance and great quality at an affordable price.

Each Tempest subwoofer features a heavy gauge stamped basket.  Double stacked magnet slugs.  All steel cut from ultra-low carbon 1008 grade (not 1012 or 12L14 like most other manufacturers use).  Custom wound 2.5" 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.

Tempest - the perfect driver for low cost, high performance home theater applications.
