Invisible Integration: The Sonance IS4 C speaker is designed to be fully concealed within walls or ceilings, offering an entirely invisible installation. This makes it an ideal choice for spaces where aesthetics are a priority and where traditional speakers would disrupt the visual flow.

Wide Frequency Response: The speaker delivers a broad frequency response of 40Hz to 20kHz ±3dB. This wide range ensures a rich, full sound with crisp highs and deep lows, providing a balanced audio experience across various types of media.

170º Hemispherical Dispersion: With its 170º hemispherical dispersion, the Sonance IS4 C ensures even sound coverage across larger spaces. This wide dispersion reduces the need for multiple speakers, providing a more efficient audio solution for expansive rooms.

Customizable Finish Options: The speaker features a paper surface that can be customized with up to 1/8” of flexible material, such as joint compound, plaster, wallpaper, or even wood veneer. This allows the speaker to blend seamlessly into different types of interior designs.

Voltage Flexibility: With 70V, 100V, and 8-ohm bypass capabilities, the Sonance IS4 C offers flexible impedance options. It features 6 different voltage tap settings, allowing for optimal performance in both residential and commercial environments.

Built-In Enclosure: To prevent sound leakage into adjacent spaces, the speaker is equipped with a built-in enclosure. This ensures that the sound remains confined to the intended area, preventing audio disturbance in nearby rooms.

Trusted by Luxury Brands: The Sonance IS4 C is used in high-end environments, including luxury retail spaces like Louis Vuitton, Gucci, Prada, and Miu Miu, due to its combination of sleek design and exceptional sound performance.

Overload Protection: The speaker includes three independent self-resetting gel switches for low, mid, and high frequencies. This overload protection ensures long-term reliability and durability.

UL Safety Certification: For peace of mind, the Sonance IS4 C speaker is UL rated for safety (UL 2043 and UL 1480), meeting industry standards for performance and safety.
