When looking at their previous generation, REL found a way to upgrade nearly every aspect of their S series. Looking for stronger and deeper bass, REL turned to an incredible 800 Watt “NextGen5” amplifier, then applied filters, films, and upgraded the modularity of the sub.
The active woofer of the S/812 has now been backed up with a film of pure carbon fiber, in order to strengthen the cone and eliminate bass reversion. These upgrades were necessary due to the increased amplifier power and the thinness of the S/812’s cone.
The passive radiator on the bottom of the S/812 now has a longer throw and contains special suspensions that allow it to remain stiff while active. This new radiator system also allows the S/510 to “act like a sealed box compact 12” design at low volumes and a high output 14” design at its limit”.
A 45% increase in power means large power reservoirs and stronger bass extension, while also delicately opening up the mids and highs in your system. The extra power also greatly helps these subs in a home theatre use case.
Taking a reference level feature and bringing it to the S series, REL has now allowed for the 4/6-fold stacking of subs in this series, so you can feel the bass and its true 3-dimensional impact.
