Helix P 10W 10" subwoofer

P 10W

10“ / 250 mm subwoofer with aluminum diecast basket and extremely stiff Kevlar / paper sandwich cone, optimized for use in a compact vented enclosure

There are only a few manufacturers who understand the art of improving an already excellent basis. HELIX has optimized the new woofer with loving attention to detail and included elements of the legendary SPXL 12 in the high-precision series. The rubber surround is not only sewn to the cone, it is also firmly screwed to the basket using the machined mounting ring. The cone itself – a Kevlar / paper-sandwich design – is also new and stiffer than before to withstand even the strongest impulses without warping.

  • Extremely stiff Kevlar / paper sandwich cone
  • Oversized voice coils with an impressive winding height for maximum electrical power handling and high linear excursion
  • Large magnet systems for low Qts, ideal for compact bass-reflex enclosures
  • Double-vented voice long-stroke coils for minimized compression effects
  • Aluminum diecast basket with diamond cut surround mounting ring
