W 165 A - 2 Ohm

Art. No. 9046

16.5 cm (6.5“) woofer with black glass fibre cone, metal basket and robust rubber surround. Thanks to a perfected selection of materials and adhesives, the loudspeaker can also be used under extreme environmental conditions, like in extreme heat or coldness and provide the necessary bass foundation.The computer-optimized suspension geometry, focused on a very high excursion but a small installation space at the same time, allows enormous sound pressure levels without fear of a sudden limitation. This makes the W 165 A the perfect game partner, especially when it comes to high robustness.

Typical applications

  • Outdoor PA systems
  • Speaker systems for saunas
  • Loudspeaker for solariums and damp
  • Loudspeaker for boats and ships
  • Sound modules in auto motive area for noise simulation
  • Exhaust systems
  • ANC systems for noise reduction


  • weather-resistant
  • Suitable for outdoor applications
  • IP 64
*Gross price for private customers. Industrial prices are available on request.
