SICA 4 Inches : 20mm Voice coil : Ferrite Magnet : 4 Ohms : 70 watts Dual Cone Professional Speaker 4 D 0,8 CS

The SICA 4 D 0,8 CS is a compact 4-inch dual cone professional speaker designed for clear and efficient audio reproduction in PA systems, custom speaker cabinets, studio monitors and other sound reinforcement applications. With a 20mm (0.8-inch) voice coil, ferrite magnet and 70W power handling, it offers a practical combination of compact size, dependable output and broad frequency coverage. The 4-ohm impedance makes it suitable for compatible amplifier and speaker designs.

Compact Design with Wide Frequency Coverage

The 4-inch dual cone speaker is designed to provide balanced reproduction across a stated 140 Hz to 20,000 Hz frequency range. Its compact format makes it useful where installation space is limited while still requiring clear midrange and high-frequency performance.

The dual cone construction supports broad sound dispersion, making the driver suitable for vocals, speech, background music and general-purpose audio applications.

70W Power Handling

With 70W power handling, the SICA 4 D 0,8 CS is suitable for compact and medium-power audio systems. Its 20mm voice coil uses an Epotex former, designed to provide thermal stability during operation and support consistent performance when the speaker is used within its recommended specifications.

The 87.5 dB sensitivity enables efficient conversion of amplifier power into acoustic output, making the speaker a useful option for systems where efficient sound reproduction is required.

Ferrite Magnet and Dual Cone Construction

The ferrite magnet circuit provides stable magnetic performance and dependable operation. Combined with the dual cone structure, it helps deliver consistent sound across the driver’s operating range.

A water-resistant cone treatment adds protection against moisture and humidity, making the speaker suitable for applications where environmental exposure may be a consideration. Proper enclosure design and installation are still recommended for long-term outdoor use.

Versatile Audio Applications

This SICA 4-inch professional speaker can be integrated into compatible PA systems, compact sound reinforcement cabinets, studio monitors, custom speaker enclosures, commercial audio installations and general-purpose sound systems. Its 4-ohm impedance should be matched correctly with the amplifier and overall system design.
