The Powerful 212/SE

Quality Meets Quantity

We believe in quality first, not simply power and boom. We believe that 1,000 watts is only desirable if it’s conveyed with speed and control. Which is why the 212/SE was engineered to not only make your heart pound and walls shake, but restore midrange warmth and harmonic structure, while providing a powerful, rich low-end. This combination of speed, power and grace driving multiple room modes (forward, down and rear) makes it ideally suited for high end 2-channel, grand rooms and dedicated theaters, allowing larger state of the art speakers to spring to full voice.

Double Down

Twin Continuous Cast™ Alloy Bass Engines

To produce our highest output single-box solution, we doubled up on the Continuous CastTM Alloy Bass Engines that bring critical acclaim to Serie S, altering them slightly for this twin front-firing configuration. These twin actives are responsible for 212/SE’s incredible speed and tactility. Our Continuous CastTM Alloy Cones reduce moving mass while maintaining rigidity, producing far more speed and precision than prior designs. These twin long-stroke 12″ bass engines, partnered with (2) matching 12″ passives provide the speed quality of a REL with a power never felt before. This combination offers the driven surface area of twin 17” drivers in a cabinet just 16” wide.

driver

Sound Beyond Its Size

Dual Continuous Cast Alloy Passive Radiator

The 212/SE uses two matching Continuous Cast Alloy passives that are stiff, lightweight and incredibly well behaved. Our approach to passive design results in performance more akin to a variable ratio driver size – as more power and deeper bass is demanded, the passive comes to life, gradually expanding the capabilities of the active engines. The down firing passive produces deep, floor-crawling bass that makes a room shudder. Mounted above the amplifier panel on the rear is the second passive. This unit produces wrap around “atmospheric” bass that adds air and shimmer to the sound. Coupling with either the rear wall or the rear corner of a room allows for bass to develop exceedingly long wavefronts and adds an ease and effortless quality unique to single-box designs.

amplifier

Command and Control

NextGen3 1,000w Digital Amplifier

Beyond our proprietary drivers, the performance of a REL is determined by our unique input filters and amplifiers. 212/SE harnesses a simple filter-type that is very fast—about 8 milliseconds in group delay– to cross out unwanted higher frequencies to our driver. This speed and gentle crossover slopes allow for seamless blending of RELs with the main speakers. RELs do not include a high pass filter to cross out bass from the main speaker because to do so would generally produce more unwanted effects than the minor benefits such a design confers. 212/SE’s power amplifier is a powerful NextGen3 1,000W (1,700 peak) digital amplifier. Our Herculean design allows each driver to output over 110 dB with ease–power enough to drive very large rooms to very high output.

wireless

Total Freedom

LongBow Zero-Compression Wireless

LongBow permits very fast, uncompressed bass to be sent wirelessly within the same room approximately 45 feet (somewhat dependent upon room clutter). We have selected an uncompressed format as it results in natural, quick delivery compared with conventional wi-fi or Bluetooth systems. LongBow also offers both high level (or low level with crossover intact) AND .1 channel delivery so that REL Theatre Reference performance can be maintained even when using our wireless delivery system.

Truly loving my twin 212SE's

I added two REL 212 SE's as subs for my main music room using a pair of Revel Salon 2 speakers. It is a two channel system in a very large space, 24'x45' . Power comes from 2 Jeff Rowland 625 SE amps, Rowland Chorus Preamp w/ PCU, Berkeley Audio Alpha Reference 2 DAC, Esoteric Transport, all top tier Cardas, Shunyata cables & Shunyata Power conditioning. The REL's are pretty straight forward to set up and w/ about one month of adjusting placement & dialing in user control variables (all by ear w/ a diversity of source material.)
Main Take aways: Very fast, seamless, essentially neutral and very very low bass capabilities. The real surprise is how much air, atmosphere, depth, acoustic/spatial information and all around musicality they add. Even on recordings that are not specifically rich in low bass, the REL 212SE make the entire system feel effortless, relaxed and capable. It is transformative in nature and beyond question exceeded what I had imagined a pair of subs might do to an otherwise very good system. I have enclosed a picture and want to advise that I ended up w/ this unorthodox placement only after experimenting w/ dozens of placement options (the conventional outside flanking position did not work best In my room.) This inside position gave the most balanced results and supplemented the lower mid's w/ an authority and rich musicality that is simple stunning. Great job REL.

Just wow!

One word AWESOME! Holy amazing. Superb! Low end and pressurization! Watching Interseller at the 1 hour mark is unbelievable! There are a few other spots in the film as well....I felt like I was in the spaceship. I replaced a great sub from Paradigm (prestige 1000) but the 212/SE is in a whole other universe.

My 212/SE (running high level and .1) is paired up with:

- Totem tribe IIIs for LCR powered by a Parasound A31
- Totem tribes for the surrounds, Totem KINs for the 4 Atmos channels all powered by an NAD Masters M27 Amp
- An Anthem MXR720 runs the show
- also have a T/9i paired up with the center (awesome as well)

All the *oomph* I needed

I've added a 212/SE to my hifi setup (NAD Masters + Totem Wind speakers). While the Winds already have an excellent bass output, the REL 212/SE delivers a crisp, substantial low level layer. When the bass (drum) kicks in, this excellent sub yields not only the sound but also the feel. Amazing. Oh - it's across the room, Longbow connectivity is a miracle.

Superb performance and looks

Well, I am
Probably the most vocal on how happy I am about selecting a pair of 212SEs when I designed my HT last fall. They met all my requirements from their capability to provide a controlled, clean, crisp and the ability to blend extremely well with my B&W 803 D3 Mains. Best decision I have ever met. Thank you Rel Acoustics.

"In a word, the REL 212/SEs are sublime. Like a linebacker who loves to paint, they have the ability to hit hard when called for, but their more gentle side allows delicate brush strokes that infuse the midrange and upper frequencies with three-dimensional body and sheer presence"
