Auna SBC-4121 Pair of 800W 4" Audio Car Speakers

Powerful performance from 4" car speakers in a 3-way coaxial design and a maximum of 400W power.

Eye-catching metallic-red membranes. High-quality materials and an elegant design.

The Auna SBC-4121 is a pair of bass-heavy, 3-way coaxial designed speakers with a maximum of 400W of power.

The membrane materials of the Auna SBC-4121 were carefully considered to ensure clarity of sound, particularly in the midrange, and to push sounds to their limits without distortion. In addition, the comparatively large ASV voice coils are used to improve performance.

The neodymium tweeter creates a very strong magnetic field, which increases the sensitivity of the voice coil to further optimize the sound quality.

The Auna SBC-4121 are also aesthetically pleasing, standing out from other plain speakers with eye-catching metallic-red membranes.
