Rel 12″ Subwoofer
$8,499AUD inc. GST
The REL 212/SX is a statement‑level subwoofer engineered for listeners who demand both immense low‑frequency power and audiophile‑grade precision. Designed as the evolution of REL’s acclaimed 212/SE, the 212/SX brings together advanced driver technology, a massively capable amplifier, and REL’s signature high‑level integration to create one of the most dynamic and articulate subwoofers available.
At its core, the 212/SX uses a quad‑driver array:
- Two 12″ active Continuous CastAlloy™ drivers mounted on the front
- One 12″ down‑firing passive radiator
- One 12″ rear‑firing passive radiator
This multi‑driver configuration allows the subwoofer to energize a room in multiple acoustic modes simultaneously, producing bass that is not only deep and powerful but also evenly distributed and richly textured. The active drivers deliver fast, controlled punch, while the passive radiators extend low‑frequency reach and add atmospheric depth without introducing port noise.
Driving this system is a 1000‑watt NextGen5 Class‑D amplifier, providing enormous headroom and instantaneous current delivery. This ensures the 212/SX can reproduce everything from explosive home‑theatre effects to the subtle low‑end nuances of acoustic recordings with equal authority. REL’s ultra‑fast filtering and updated driver suspensions further enhance transient speed, clarity, and micro‑detail.
The cabinet is tall, slim, and beautifully finished in piano‑black lacquer, giving the subwoofer a refined, architectural presence. Heavy internal bracing and precision‑machined feet maintain stability and reduce resonance, allowing the drivers to operate with maximum accuracy. Despite its size, the 212/SX integrates seamlessly into both high‑end stereo systems and large‑scale home‑theatre environments.
Connectivity includes REL’s renowned high‑level Speakon input, low‑level RCA, and LFE RCA/XLR options, ensuring compatibility with everything from integrated amplifiers to AV processors. The subwoofer is also compatible with REL’s wireless systems for flexible placement.
The REL 212/SX is built for large rooms and demanding listeners who want deep, room‑shaking bass without sacrificing speed, musicality, or refinement. It stands as one of REL’s most capable designs—powerful, elegant, and engineered to elevate any premium audio system.
