The REL S/812 forms part of the pretentiously titled Serie S range of subwoofers, but never a company to do things by half, the latest additions are a total transformation of REL’s mid-sized class of subs. As a result, unlike the previously released 212/SE, the new S/812 represents a complete revision of the line-up that adds new upgrades and design features.
For a start, the cabinet has been revised, and the feet replaced with rails. The NextGen5 amplifier has also been upgraded to deliver more power, and the ultra-lightweight ContinuousCast alloy cone redesigned to handle the increase in slam. Improved filters tailor the LFE channel to deliver twice the output between 19 and 35Hz, while the high-level and low-level inputs use a new PerfectFilter. Finally, these redesigned subwoofers can also be stacked up to three units high.
The REL S/812 has a completely redesigned cabinet that is lower, wider and deeper, using dimensions based on the company’s Reference Series. The build quality is superb, and despite essentially being a cube, the S/812 is unusually attractive for a subwoofer. This is the kind of sub you wouldn’t mind having on display, rather than hidden away in a dedicated home cinema.
