High-performance active subwoofer with 30 cm long-throw woofer and class D amplifier

DEEP, POWERFUL BASS FOR CINEMA-QUALITY PERFORMANCE

Whether spectacular movie effects or a noticeable expansion of musical depth - the RS 12 adds raw power, impressive clarity and precise control to your sound system.

Experience bass the way it's meant to be heard - powerful, rich and deeply immersive. Equipped with a powerful 12″ / 30 cm woofer, the Alpha RS 12 is capable of reproducing frequencies down to 20 Hz – for bass that you not only hear, but feel.

The integrated Class D amplifier delivers up to 240 watts of peak power and ensures precise control even at high volumes. Whether it's the thundering rumble of an explosion in a movie or the subtle pulse of a bass line, this subwoofer impressively brings your home theater or music system to life.

The Alpha RS 12 can be easily integrated into almost any system - whether modern or classic. It has both RCA inputs (low-level) and high-level speaker inputs, making it possible to connect it to AV receivers, stereo amplifiers and even vintage setups without a subwoofer pre-out.

An adjustable crossover frequency (50–150 Hz), a switchable phase switch and the automatic standby function (< 0.5 W) ensure easy setup and energy-efficient operation.

Whether used in a 5.1, 7.2 or stereo system, the RS 12 adds crucial low-frequency energy to the sound and transforms the entire soundstage. By relieving the main speakers of reproducing low frequencies, it improves detail resolution, expands dynamics and gives films, music and gaming an impressively realistic presence.

From massive cinema explosions to the finest bass nuances - this subwoofer completes your system with immersive authenticity.

UNSERE TECHNOLOGIEN

ENGINEERED FOR POWERFUL BASS

The Alpha subwoofer delivers deep and precise bass thanks to a carefully engineered combination of components. Its advanced magnet system keeps the woofer movement stable and accurate, reducing distortion even at high volumes. A ventilated voice coil helps prevent overheating, ensuring reliable performance during long listening sessions. The rigid, coated paper cone is designed to move smoothly and respond quickly to changes in the audio signal, resulting in clean, powerful low-end sound that adds real impact to your music and movies.

FRONT-FIRING SUBWOOFER WITH AIRFLEX PORT TECHNOLOGY

The Alpha RS subwoofers feature a front-firing design coupled with a dual reflex port configuration, engineered for maximum acoustic efficiency. The twin Airflex ports are precisely tuned to minimize air turbulence and port noise, even at high output levels, ensuring clean and distortion-free bass performance. This front-facing layout enhances low-frequency dispersion and makes room placement more flexible, delivering consistent, punchy bass response across a wide listening area.

EFFICIENT CLASS-D AMPLIFICATION WITH FLEXIBLE TUNING OPTIONS

The Magnat RS 12 features a powerful and efficient Class D amplifier, delivering precise, dynamic bass with minimal heat generation. Designed for seamless integration into any AV setup, it includes active frequency response equalization (LPC circuit) up to 150 Hz, ensuring smooth transitions between subwoofer and main speakers. The amplifier offers flexible tuning options with adjustable volume, crossover frequency, and a phase switchable from 0° to 180°. Connectivity is equally versatile, with stereo high-level inputs via screw terminals. For added convenience and energy efficiency, the RS 12 includes an automatic standby function with ultra-low power consumption under 0.5 watts, and supports universal mains voltage from 110V to 240V at 50/60 Hz.

ROBUST LOW-RESONANCE CABINET WITH ACOUSTIC DECOUPLING

The Magnat RS 8 features a robust, low-resonance MDF cabinet designed for both performance and versatility. 

Large feet with resonance-absorbing rubber inserts ensure optimal decoupling from the floor, reducing vibration and enhancing clarity. A removable front grille offers flexibility in appearance and protection, making the RS 12 a seamless addition to any home theater or hi-fi environment.
