The most compact model in the renewed S Series from one of the undisputed world leaders in high-quality subwoofers, the S / 510 offers a unique concentrate of technological and aesthetic refinements that make it a perfect choice to complete bass response of all kinds. of High Fidelity and Home Theater systems. There are numerous enhancements to be found inside and outside of the S / 510, starting with a beautifully newly developed enclosure topped off by a subtle bronze trim that streamlines its visual appeal. On the other hand, the replacement of the feet by ultra-stable rails slightly advances the main enclosure to the point of giving the sensation of floating in space. If we go inside, we find both qualitative and quantitative improvements, the first being an amplifier that constitutes an improvement of the NextGen3 used previously in REL Acoustics reference models, its continuous output power being 500 watts. This power is necessary to handle with authority the special filters responsible for adapting the .1 / LFE channel, which allow the output level to be almost doubled below 40 Hz. Regarding the High Level and Low Level inputs , highlights the inclusion of a new filter called PerfectFilter designed specifically for Hi-Fi applications in which High Level inputs are used. To conclude, let us note the use of an improved version of the ultralight transducer incorporated for the first time in the original S Series, which increases the rigidity of the cone by 60%, thus obtaining superior response speed, delicacy and precision. .
