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. 120 °C temperature resistant.
Typical applications:
- Outdoor sound reinforcement systems
- Speaker systems for saunas
- Weatherproof network column speakers
- Boats, ships and open vehicles
Attributes:
- 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)
- ball-resistant
