Ultra-slim dual-cone stereo speakers – pair in a 4″ size and black finish are designed for built-in marine audio where space behind the mounting surface is limited. The set consists of two round stereo speakers with 2 × 10 W RMS power and 2 × 20 W peak power.
The dual-cone design uses a double cone and should not be confused with a separate 2-way speaker with a dedicated tweeter unit. The speakers have a frequency range of 90–18,000 Hz and a sensitivity of 90 dB.
The housing is made of ABS, while the speaker cone is made of polypropylene. The construction is waterproof and UV-resistant for use in exposed maritime environments. No numerical IP rating is specified.
Each speaker has an outer front diameter of 133 mm and requires a round cutout of Ø95 mm. The total depth is 38 mm, while the necessary mounting depth behind the surface is only 23 mm. During installation, the distance to a magnetic compass must be at least 0.80 m.
