Subwoofers are essential for cinematic sound, providing the deep, physical impact that brings on-screen action to life. MAG Theatron continues to innovate and proudly presents the SBV21, setting a new standard in home cinema subwoofers. This latest creation is a masterpiece of design by our engineers.

The MAG Theatron SBV21 is a high-performance subwoofer crafted to provide powerful, immersive sound experiences in your home theater. Thanks to cutting-edge technologies, it redefines expectations with a frequency response that reaches a convincing infra-low 19 Hz, delivering a nominal power of 1000 W and a maximum continuous sound pressure level of 128 dB — offering an unparalleled experience that surpasses the capabilities of even full-scale commercial cinemas. 

At the heart of this powerful subwoofer is a state-of-the-art 21-inch low-frequency driver, featuring a massive 4.5-inch voice coil that eliminates thermal compression, always ensuring consistently high sound quality. Advanced technologies, including dual demodulation rings and a triple cooling system for the voice coil, significantly reduce distortion, guarantee parameter stability and increase reliability.

Our innovative Woofer Invisible Vent Technology (WIVT) integrates concealed bass reflex ports that guarantee silent operation, preventing any screen disturbances caused by airflow. This allows you to focus solely on your cinematic experience. The SBV21 also offers versatile installation options with its antishock mounting system and a compact cabinet depth of just 500 mm (15 3/4 inches), saving valuable space behind the screen and making it easy to integrate into any home theater setup.

In summary, the MAG Theatron SBV21 redefines the standard for powerful behind-screen subwoofers. It effortlessly handles infrasonic frequencies, delivering a palpable impact that physically immerses viewers in the cinematic experience, even in larger rooms. It’s the ideal companion for any high-end home cinema setup.
