Frequently Asked Questions

Is the Magnat Alpha RS 12 suitable for use in an apartment?

Although powerful, the Magnat Alpha RS 12 features settings that allow you to adjust its sound level. It can therefore be used in an apartment, but it is recommended to set it moderately to avoid disturbing neighbors, especially since low frequencies easily travel through walls.

Can two Magnat Alpha RS 12 subwoofers be used in a stereo configuration?

Yes, it is entirely possible to use two Magnat Alpha RS 12 subwoofers in a stereo configuration. This would provide a more even distribution of bass throughout the room and potentially achieve even higher sound levels.

Does the Magnat Alpha RS 12 require a break-in period?

As with most speakers, a short break-in period can be beneficial for the Magnat Alpha RS 12. This allows the mechanical suspensions to loosen up and reach their optimal performance. Normal use over a few dozen hours is usually sufficient for this process.

The Magnat Alpha RS 12 is a perfect addition to my Magnat S70 speakers, and you can also adjust it perfectly to the speakers themselves with the volume and frequency knobs, I am very satisfied with it, the price/quality ratio is also perfect
