Revel Performa3 B112 Powered Subwoofer

1000-watt 12" Powered Subwoofer

This new unit maintains a precise engineering balance between the voice coil, spider and surround that produces linear motion of all three for lower distortion by incorporating CAD/FEA optimized high-linearity motor geometry:

The extremely long (50mm) two-layer copper voice coil gives this transducer a very high Xmax, dramatically increasing output. A fiberglass voice coil former helps the voice coil withstand high temperatures, reducing power compression and helping increase output. A cardboard spacer added at the top of the voice coil former maintains motor geometry, creates a solid attachment joint and prevents deformation of the voice coil at high outputs.

The spacer also eliminates the typical single fulcrum point between the spider and cone on the voice coil former, minimizing voice coil rocking modes during hi-power operation.
