P 6B

SKU: P821600


Midbass 6.5″ 100W


The details make the difference – don’t get mislead by the discreet visual appearance of the P 6B. This driver is definitely a perfect basis for a top-class sound system. Its unique glassfiber-paper compound cone combines minimum weight with maximum stiffness and perfect inner damping. To further reduce the moving mass an 1-inch / 25 mm voice coil has been chosen which nevertheless can easily handle up to 100 Watts RMS due to its extremely high temperature resistance. It’s not only the powerful kick bass and the uncoloured midrange response but also the exceptional low distortion which makes the P 6B a “winner”.


  • Novel glassfiber-paper compound cone for maximum stiffness combined with lowest moving mass and perfect inner damping
  • Special shaped rubber surround for long linear cone excursion
  • Gold-plated terminals
  • Individual HELIX design basket
  • Solid rubber magnet protection ring with HELIX logo
  • Grille included
