Visaton FR10WP

The Visaton FR10WP is a 4-inch marine speaker specifically designed to withstand harsh conditions, including saltwater environments. With its robust design and specifications, it is ideal for use on boats, ships, and other marine applications where the speaker may be exposed to moisture and corrosion.

The speaker has a nominal power handling of 20 W with a maximum of 30 W, and a nominal impedance of 4 Ohms. Its frequency range spans from 80 Hz to 16,000 Hz, providing good coverage across the audio spectrum. With a mean sound pressure level of 85 dB at 1 W/1 m distance, it delivers solid audio performance.

The Visaton FR10WP features a dispersion angle of 76° at -6 dB at 4000 Hz and has a mechanical excursion limit of +/- 2 mm. Its resonance frequency is 120 Hz, with a magnetic induction of 0.85 T and a magnetic flux density of 290 µWb.

The speaker has a frame height of 4 mm and a voice coil with a diameter of 20 mm and a height of 5 mm. The recommended mounting hole diameter is 101 mm, and the speaker weighs only 0.275 kg.

The Visaton FR10WP has a DC resistance (Rdc) of 3.8 Ohms and mechanical and electrical Q-factors (Qms and Qes) of 3.13 and 2.14, respectively. The total Q-factor (Qts) is 1.27. The equivalent volume (Vas) is 2.1 liters, and the effective piston area (Sd) is 50 cm². The moving mass (Mms) is 5 g, and the force factor (Bxl) is 2.75 Tm. The voice coil inductance (L) is 0.3 mH.

The speaker comes in white and features terminals for 4.8 x 0.8 mm (+) and 2.8 x 0.8 mm (-). It also has an IP66-rated protective system, meaning it is shielded against dust and powerful water jets from any direction. The operating temperature range spans from -40 °C to 80 °C, making it suitable for various climate conditions.
