Invisible Upgrades to S/812’s Bass Engine
Pure Carbon Fiber Backing
S/812 required upgrades to its ContinuousCast™ Alloy Cone to allow it to survive the massive power upgrades. To permit its thin, aluminum cone to survive 800 watts and incredibly long stroke, we added an ultra-lightweight backing of pure carbon fibre, strategically placed over portions of the rear surface of the cone. This produces two benefits; it strengthens and stiffens the cone and also eliminates reversion, wherein the backwave inside the cabinet is now prevented from interfering with the main launch of bass into the room. The result is more accurate and far louder deep bass.
There is Nothing Passive About These:
Carbon Passive Radiator
Our uniquely tuned passive radiators use special suspensions, now with an additional 30mm of linear travel, to produce performance far beyond conventional subwoofers. Our new SuperProgressive™ passive radiator produces extremely long travel allowing for very loud output while retaining the variable stiffness of its suspension. This allows it to act like a sealed box compact 12” design at low volume and a high output 14” design at its limit.
Warning: Power Amplifier on Steroids
800 watts and Counting
At 800 watts the NextGen5 amplifier is borrowed from our reference models and rocks huge reservoirs of power and current. The 45% increase in power (previous version was 500 watts) is needed to deliver both the profound output levels needed for modern theatre, as well as to produce the deepest bass in a high end 2-channel system. This increase in power is necessitated by our development on the musical front of an all-new circuit termed PerfectFilter™ that balance both frequency extremes.
PerfectFilter performs two seemingly disparate qualities; extending the strong, even response of the extreme low end of bass frequencies while simultaneously opening up air and delicacy in the middle and high frequencies of one’s system. Additionally, we applied customized PureTheatre™ filters to allow S/812 to deliver the most awe-inspiring theatre effects ever offered in a classic REL.
Serie S Line Array
Stacked for Ultimate Performance
In the real world, bass occurs with width, depth and height. By stacking up to three units per side (stereo or theatre main L-R speakers) the proper perspective and height of sonic events are illuminated. This elevates reproduction from conventional stereo or theatre to a floor-to-ceiling panoramic, full scale perspective of each sonic event. Reviewers are lining up to marvel at the transformation of music and film into the full-scale representation that REL Line Arrays uniquely deliver.
I have always loved REL subwoofers and always will. I recently moved to a larger single family home and my older S3 was too small for the family room. After watching 1 movie, I knew it was time to upgrade the S3. I received my new S812 yesterday and set it up last night. I only sampled some scenes from Rocketman last night and I'm simply blown away by the improvement! This was money well spent. If you like high end audio, you will LOVE this subwoofer!
S/812: Great packing on shipment. Black gloss is beautiful.
Easy installation. Sounds perfect. Placement tuning gave about +5db, rotation +0db, the crossover was difficult for me to hear a major change.
I have lots of tube traps which smooths out the room. I used an iPhone app to create a live FFT
waveform and then compared different positions and watch the change in the low-frequency response.
I used tracks 4 and 5 of the CD Best of Food for Woofers by Bass Mekanik. Room is 16x37x12 to the ceiling.
Traps in corners and across the front of the room over fireplace what is not used in Arizona.
I bought two S/5’s 6 months ago for my 2.2 system. After falling in love with them I decided to move the S5’s to the 5,2 theatre system and buy two new S812’s for my 2.2 system.
There is a noticeable improvement in the lower range bass with the 812. Other than that, they are both awesome units.
I did notice the owners manual says they are rated 700W with a NexGen3 amp. Not 800W and NexGen5 as advertised. They should correct this. It’s still a good upgrade of the line.
First I must say thanks to the entire Rel team who spent A LOT of time helping me understand their products and choose my new sub. I have Focal Sepora No.3 front speakers and needed a powerful sub to play with them. John helped my choose the S-812 and I could not be happier. The speed, accuracy, and definition make this an incredible find. I purchased 2 for a stereo sound, but had to return one secondary to damage and decided that I did not have the room for 2. John and Rachel were very helpful in first helping my decide if I should keep the 2nd sub and then the return process. I was going to place the 2nd across the room and use wireless technology, but Justin helped me understand the sound field would not be stereo and not what I was looking for. Please watch all the videos John put together and if you still have questions the support team, including John, will answer any and all your questions. Excellent company and excellent products.
Reviews + Awards
There are plenty of cheaper subs, and some can even go nearly as deep as the S/812, but they’re unable to mine such depths while remaining so composed. Good bass shouldn’t dominate, it should be an integral part ofyour cinema soundstage, adding low-frequency impact where needed. This is what the REL S/812 achieves so well – it goes deep with control, shows effortless speed and agility, and can seamlessly blend with your other speakers to enhancing whatever you’re watching.
