FRS 10 WP - 8 Ohm (white)

Art. No. 2103

Saltwater resistant 10 cm (4") full-range driver with glas fibre cone, plastic basket and grille. Balanced frequency response, high efficiency and good high-midrange reproduction. Long time weather proved and therefore especially suited for out-door sound reinforcement systems, swimming pools, sauna and speaker for boats, ships and open vehicles. Also suitable for model boat applications.

*) IP protection class for front side when built into a sealed enclosure

Typical applications

  • Outdoor sound reinforcement systems
  • Speaker systems for saunas
  • Weatherproof network column speakers
  • Boats, ships and open vehicles


  • suitable for outdoor applications, seawater proof
  • functionally at low temperature according to EN 60068-2-1 (-40 °C; 96 h)
  • up to the standards of the Germanischer Lloyd (requirements for electrical equipment/low temperature)
  • Plastic: PC (UL 94: V-0)
  • temperature resistance 120 °C
  • ball-resistant
