VIBE 12" BANDPASS ACTIVE ENCLOSURE The BlackAir Vented enclosure is loaded with the BlackAir 10” or BlackAir 12” Subwoofer, an engineering masterpiece of subwoofer design known for it’s perfect balance of power and precision. a) The front gasket is made from high quality machined aluminum for a high-end aesthetic to complement the bold yellow fiberglass cone design. b) The BlackAir’s striking yellow cone was designed using FEA (Finite Element Analysis) for optimum rigidity to weight ratio, the hybrid woofer cone is made from an absorbing polypropelyne and fiberglass. The result is increased depth and clarity of bass. c) The BlackAir’s dual progressive poly-glass spiders provide control and stability of the woofer cone whilst minimizing weight. d) Whilst traditional rubber surrounds will have different suspension characteristics at the extreme ends of excursion; The BlackAir features a specially developed foam rubber multi-roll surround allowing much better linearity throughout the subwoofers excursion range. e) The angular torsion basket provides rigidity and support for the motor and moving parts of the subwoofer. The 5 vented arms of the torsion basket cradle the coil and allow it to breathe cool air when in motion. f) The subwoofer motor was designed using FEMM (Finite Element Method Magnetics) giving linear flux saturation and low distortion, to ensure great sound quality. Using FEMM we can use the maximum magnetic force of the magnet to drive the cone.
