Classic 99

Plays louder and reaches deeper with layers of subtle textural enhancements that continuously impress.

Classic 99 extends our Classic Line to loftier heights. Richer, bolder, and more powerful? Certainly. Yet 99 is also capable of far greater nuance, air, and resolution than its lesser brethren. For those with more capable systems and larger rooms, Classic 99 delivers advances on every front, while still maintaining the same easy-going, room-filling nature all Classic offerings possess. The high-grade genuine dark walnut veneer complements a variety of decors. Classic 99 delivers this in the same simple, comforting form of Mid-Century Modern design. Perfect for those who welcomed the original, yet were waiting for the next chapter to be written, those who crave even higher performance and the ability to fill larger, grander spaces with a broad carpet of deep bass. You’ll still want to put on a record, pour a favorite drink, sink into your favorite chair, and relax into the music or movie of your choice. Classic 99, for those who waited for more.

Features

  • 450-watt Class D Amplifier
  • 12" Pulp-on-Paper Driver
  • Acoustic Suspension Cabinet Design
  • Classic Real Walnut Veneer

Nothing Continues to Say Lifestyle like Mid-Century Modern RELs

Designed to Be Superior

Classic 99 adopts the form language introduced in its model 98 stablemate. As comfortable as a pair of well-worn loafers, it features solid cabinet walls as thick as 32 mm, clad in rich, warm walnut veneer, hand fitted with care. The simplest of natural aluminum badges and softly radiused feet milled from solid billet, blacked out to allow it to seemingly float, ensure that nothing, not even a grille disturbs the vibe. Yet, as with all RELs, the styling conveys far more than simple comfort. The down-firing 12” driver, while unseen, will surely be felt. Continuing to the rear panel, one finds the period-correct detailing extends to the amplifier panel, where all controls are finished in lovely white gold. Everything that one encounters has the heft of quality switch gear, even the click made by the phase switch is near perfection. Quality abounds everywhere one looks or touches. Don’t be surprised if your children fight over it later in life.

Driven to be Louder. And Quieter.

As anyone familiar with REL will tell you, we always begin with the driver. In this case, a bespoke 12” long stroke driver that uses lightweight, stiff, hot-pressed paper to form the main body of the cone. Laid atop that is a stiff center cap made of hand-thrown paper; to randomize the fibres, ensuring that the driver has excellent self-damping. This is one of REL’s secrets. Understanding that it is the quietness, that attention to bring the driver to complete silence, that produces the most startling dynamics. Whilst Classic 99 will play shatteringly loud, it’s from the very black background that the loudest dynamics emerge to produce the sense of shock sought by great composers and directors.

More than Ample Amplification

Classic 99 is big, bold, and full of character, similar to the Stentor II of our youth, but at one-third the price. Of course, the 99 has a great amp. In order to generate deeper bass and significantly higher output, we turned to a tried-and-true Class D amplifier that we’ve already used in thousands of previous units. This 450 watt amplifier is fed by an all analogue PerfectFilter™ front end that extends useful output well into the low 20 Hz range - superb for a design of this size and price. It produces a sound that’s both rich and richly detailed at the same time. Classic 99 borrows the best from current technology to deliver a sound slightly warmer and more like what we all imagine vintage sound to be, with superior reliability and performance than was ever available back in the day.

Less Wiring?

The future meets the past gloriously in REL’s wireless offerings. For the ultimate, select our Airship II which encourages the use of REL’s High-Level Connection PLUS .1/LFE should your listening tastes run toward movies. And these days who doesn’t stream quality video content? This is our ultimate wireless design at 5.8 GHz and uses discrete components in the front end to transform your system’s sound flawlessly into totally uncompressed wireless capable of eliminating the sprawl of cables across one’s living space.

On a tighter budget? We slip the exact same 5.8 gig master chip into an affordable system that allows for Low Level or .1/LFE to deliver across the same 35’ with the same bulletproof signal delivery that we’ve become famous for over the past 15 years. HT-Air MKII Wireless is one of life’s great bargains.

Special Performer

"I know REL subwoofers so well by now the 99 only took me about 10 minutes to setup and be very happy with how it was integrated. I listened across a very wide variety of music including modern electronic heavy hitting bass, female vocals, folk music and modern jazz-ish stuff, audiophile stuff, some drum and bass and a real mixture for several days occasionally unplugging the REL to remind myself of what it was doing."

No cat claws allowed!
Color: Cypress, Size: Twin, Color: Cypress, Size: Twin
The quality of this set isn't the best. It you have a cat, a sharp claw or two will do visible damage! I actually clipped the loose threads off days ago, but there's still that double track of claw marks that will always be there. The pillow sham is also huuuge and looks awkward on a twin bed. It you have a large pillow it should be ok. The pillow sham isn't sewn together properly either, the fabric is bunched up where the seams meet. The comforter is pretty lightweight, so I will definitely be needing another blanket (or two!) with this one for winter. However, the set IS very soft, and it IS nice and cozy. The color in person is ok/does not look like photo advertised, as is, it would probably look nicer on a better quality set. The three stars is for comfort only. I will update this review after washing it a couple of times. Update: not even a month, and the fabric has ripped where the claw mark is. But, I have decided to keep it after all, if only for the comfort. Still not happy with the cost vs the quality. Latest update: added last 2 photos to show progression of wear. It does wash up well enough all considered. 3/31/24 Tears in the material (non-sherpa side) continue to appear. If you apply any type of tension to the fabric while making the bed, or just trying to pull the comforter over you when you roll over, you can hear the fabric tearing. I have found 6 tears to date.

Finally we BOTH can sleep comfy!
Color: 08 - Black, Size: Queen
So for years my boyfriend has always liked “jersey sheets” or “tee shirt” sheets or sheets made of flannel. He says he doesn’t like the feeling of cold “silky” feeling sheets as he’s always cold. I’m opposite and am always hot, and anytime we stayed in a nice hotel I looked forward to being able to sleep on cooler, taught, soft sheets for a couple of nights. I was able to deal with our old sheets but the issue we both hated was after awhile any sheet we got would get pilling. We even splurged and got a $60 flannel sheet which did the same thing forcing me to shave off these little annoying fuzz balls that make it feels like there is thousands of crumbs on the sheets. I also would wash our bedding once a week because the Jersey sheets seemed to “grow” as we move around in bed making it so the sheet was not taught and super annoying to lay on. The day I would wash them they would be comfortable but ultimately by the end of the week they would be almost hanging off our mattress. I ordered these sheets on a whim and got them the same day and immediately just threw out the jersey sheet and put this on (I didn’t even wash it, I know it’s gross but I was desperate for a comfy nights sleep and they came around 8pm) when I put them on I realized how soft and comfortable they felt. I also liked how the pillow cases are larger than most pillow cases that I have had in the past. We’ve been using these sheets for about a week and I love how I don’t wake up with my pillow popping out of the case anymore. The sheets have loosed ever so slightly since a week of sleeping but still are really taught and comfortable. They are cooler than flannel or fabric sheets and are initially cold when you first lay on them but I wouldn’t consider them “cooling” but they keep me from feeing extremely hot. They are way better than I ever would have expected for the price. I look forward to laying on them at the end of each day, even my boyfriend laid in bed the day I got them and said “wow I didn’t think I would like sheets like this, these are so soft!” And fell asleep immediately. We ended up ordering a second set in grey and the color is pretty. I still have yet to wash them, I usually use 2 tide pods when washing the bedding but I might get some fabric softener (as I hear it helps with pilling) to prevent the possibility of having that happen to these sheets in the future. I am hoping they hold up well after the wash and longer use. If they start to pill after wash, I will come back and update my review. Until then, I would highly recommend these sheets for the quality and the price point that they are offered at. Honestly, at this point even if they pill months from now I probably wouldn’t even be upset as long as they stay the same price I would just buy another set as they are just that comfortable and soft. UPDATE: So it has been about 3 months since I have purchase and used these sheets. They are still as soft as the day I first put them on. I’ve been washing them bi-weekly along with my comforter and pillowcases. I wash them with warm water using a combination of tide pods and added Downy fabric softener. They say to hang dry them in the description but I have been putting them in the dryer on medium and have been taking them out after around 20-25 minutes, they seem to dry extremely quickly. They have yet to have absolutely any pilling and also have not shrunk or stretched. Also I have a cat that is very active and also sleeps with me who enjoys kneading on my bed and I haven’t even noticed any signs of wear what so ever to the eye or to the feel. I highly recommend these sheets. I still have yet to even open the second set I purchased!

Happy With Our Purchase
Color: 07 - Charcoal, Size: King, Color: 07 - Charcoal, Size: King
When we opened the package the sheets were soft. We wash everything before we use it, so in these went. The sheets held nicely through the washing machine, the edges stayed sewn up and the sheets are still fluffy. The sheets fit nicely on our bed and have a nice cooling effect in this 80-degree weather. We think these sheets were a quality purchase that was affordable.
