The Magnat Alpha RS 8 is an active subwoofer designed to deliver exceptional audio performance in a compact format. This subwoofer combines power, precision, and aesthetics to seamlessly integrate into your home theater or hi-fi setup.
Impressive Audio Performance
At the heart of the Magnat Alpha RS 8 is a high-power 20 cm long-throw bass driver. This woofer features a paper cone with a special coating, offering the perfect balance between lightness and rigidity. The rubber surround allows for significant excursion, essential for reproducing low frequencies with precision and power.
The speaker’s magnetic system has been optimized using Klippel technology, ensuring a strong and uniform magnetic field. This optimization results in greater responsiveness and better transient handling, crucial for precise and dynamic bass.
The high-performance voice coil is ventilated, ensuring excellent heat dissipation. This feature allows the subwoofer to maintain its performance even during prolonged use at high volumes, without the risk of thermal compression.
Advanced Amplification Technology
The Magnat Alpha RS 8 is equipped with a built-in Class D amplifier, known for its efficiency and low distortion. This amplifier delivers a continuous power output of 80 W RMS, with an impressive peak power of 160 watts. This power reserve enables the subwoofer to effortlessly reproduce the most dynamic passages while maintaining high precision.
Class D technology also offers the advantage of low power consumption and reduced heat generation, contributing to the product’s reliability and longevity. An automatic standby circuit is included, reducing power consumption to less than 0.5 W in standby mode.
Extended Frequency Response
Thanks to its meticulous design and advanced technologies, the Magnat Alpha RS 8 can reproduce frequencies as low as 25 Hz. This extension into the low-frequency range allows you to physically feel the special effects in movies and the deepest notes of musical instruments.
The frequency response extends up to 200 Hz, ensuring a smooth transition with the main speakers. The crossover frequency is adjustable between 50 and 150 Hz, allowing for optimal integration with a wide range of satellite speakers.
Flexible Installation and Adjustment
The Magnat Alpha RS 8 offers great installation flexibility thanks to its multiple connection and adjustment options. The subwoofer features low-level (RCA) and high-level (screw terminal) inputs, enabling connection to virtually all types of amplifiers and AV receivers.
The amplifier controls allow precise adjustment of volume, crossover frequency, and phase (switchable 0°/180°). These settings make it easier to acoustically integrate the subwoofer into your listening room, regardless of its configuration.
An active frequency response linearization system is integrated, optimizing the subwoofer’s performance up to the upper crossover frequency. This technology ensures more accurate reproduction and better integration with the main speakers, even if they are compact.
Compact and Elegant Design
The Magnat Alpha RS 8 stands out with its sleek design and compact dimensions. With a width of 260 mm, a height of 350 mm, and a depth of 350 mm, this subwoofer easily fits into any interior. The removable fabric grille allows you to showcase the impressive bass driver or conceal it according to your preferences.
The subwoofer is equipped with large resonance-absorbing feet, ensuring optimal stability and reducing unwanted vibrations. This attention to detail contributes to the overall sound quality and the product’s longevity.

Frequently Asked Questions
What is the difference between RMS power and peak power?
+
RMS power (80 W for the Alpha RS 8) represents the continuous power the subwoofer can handle over a long period. Peak power (160 watts) indicates the maximum power the subwoofer can handle for very short durations, typically during highly dynamic musical passages.
Is the Magnat Alpha RS 8 suitable for both home theater and stereo hi-fi use?
+
Yes, this subwoofer is versatile and adapts well to both home theater systems and stereo hi-fi setups. Its flexible settings allow it to integrate seamlessly into both types of configurations.
How do I determine the ideal crossover frequency for my setup?
+
The ideal crossover frequency depends on the characteristics of your main speakers. Generally, the smaller your speakers, the higher the crossover frequency should be. Start by setting the crossover frequency around 80 Hz, then adjust by ear to achieve a smooth transition between the subwoofer and your speakers.

Ouahid
Bass box or subwoofer can carry the name, it's the same thing. In any case this one, the active Magnat RS 8, brings me a very important advantage: the high-level inputs for connection to an amp that doesn't have a Sub output. Everything is connected at high level, speakers and subwoofer at the back of the Magnat amp, the bass response is fantastic, bass and nothing but bass, it's brilliant, the sound is rigorously modified for the better, I even find it more amplified twice over, absolutely huge. With two adjustments: volume and frequencies. I positioned it in front of me between the two MartinLogan B2 speakers, which are also fantastic and powered by a superb Magnat MR780 amp. The whole setup is extremely powerful, too powerful for my 22m2 living room, better too much than too little. In Home Cinema, boom, on films with sharp effects it's just insane, don't be fooled by the 80 watts RMS, this subwoofer can go even higher, much higher, it just needs an amp like the Magnat or equivalent in power, more than sufficient especially in a medium-sized room of 20m2 and even more. At my place I'm barely at max 40%; if I go beyond that I tear up my sofa and my TV falls off the wall, hard to push the volume knob higher, so you can see the huuuuge margin, I'll never reach a high volume but I prefer having Sonor quality to something that saturates quickly and hearing squeaking, not for me. For a very discounted price, it's a good deal. The cabinet is not too small or too big, the wood is nice and well finished, the assembly is good. Very happy with this purchase: amp, speakers, subwoofer without costing an arm and a leg. I love it. Thanks again to HomecineSolutions for their support from start to finish on the whole order and the confidential discount.

Caisson de basses ou subwoofer peut un porte l'appellation c'est la même chose.
En tout cas celui ci le Magnat RS 8 actif il m'apporte un plus très important les entrées hauts niveaux pour un branchement sur un ampli qui n'a pas de sorti Sub.
Tout est assemblé en hauts niveaux enceintes et caisson de basses à l'arrière de l'Ampli Magnat, la réaction et fantastique des basses rien que des basses c'est génial, le son est rigoureusement modifier en mieux je trouve même plus amplifier deux fois qu'une énorme.
Avec deux réglages volume et fréquences.
Je l'ai positionner en face de moi entre les deux enceintes MartinLogan B2 elles aussi sont fantastique et alimenté par un super Ampli Magnat MR780. le tout est hyper puissant trop puissant pour mon salon de 22m2 il vaut mieux du plus que du moins. En Home Cinema Pouf sur des film avec des effets tranchants c'est juste démentiel ne vous fiez pas aux 80watts RMS ce caisson peut encore monté plus haut beaucoup plus haut il lui faut juste un Ampli comme le Magnat ou équivalent en puissance, largement suffisant surtout dans une piece moyenne de 20m2 et plus encore. Chez moi je suis à peine max 40% si je dépasse ça je déchire mon canapé et ma télé tombe du mur difficile de pousser le potard du volume plus haut, donc voyez la marge enoooorme jamais j'atteindrai un volume élever mais je préfère avoir la qualité Sonor à quelque chose qui sature vite et entendre grincer non pas pour moi.
Pour un tarif bien remisé l'affaire est Bonne.
La caisse est pas trop petit ni trop grande le bois est sympa et bien fini l'assemblage est bon. Très contant de cette achat Ampli, Enceintes , Caisson de basses sans y laisser un bras. J'Adore.
Encore merci à HomecineSolutions pour leur soutien de bout en bout sur l'ensemble de la commande et la remise confidentiel.
