Serie T/9x: Bigger AND Better

The Series Flagship

The job of any range topper for REL is to deliver more of everything, particularly output and dynamics. The 9x is no different in this regard, as it delivers the goods in both music and theatre applications. 9x, however, delivers a level of intimacy, clarity and speed that means there are no longer trade-offs between the sonic balance of smaller models weighed against the power and scale of a model 9.

The all new 9x has even greater output than before, but the headline news is the way it sacrifices nothing in clarity and transparency to achieve this. At this price it opens the pathway for owners of high performance European floor and stand mounted monitors and smaller panel speakers to enjoy truly full range sound.

design

Reimagined, Then Reengineered

A completely redesigned flagship

Many don’t realize the intense linkage between performance and design here at REL. Performance is everything to us and so it drives physical design revisions. Our engineers, recognizing the need for greater acoustic volume to achieve the goals of greater fluidity and power, turn to the designer who works dimensions to fool the eye into seeing a smaller, more compact footprint even though cabinet volume increases. Using gently rounded corner radii that allows the eye to flow over and see less visual mass. The result is both modern and familiar with no unnecessary adornment.

driver

Outsized Performance

Innovative Alloy/Fibre Bass Engines

To achieve higher output with better control requires a complete overhaul of the suspension components. Much like the suspension on a sports car, these items are responsible for the tuning and feel of our designs. By increasing the cabinet volume, efficiency is improved yielding higher output for no more amplifier power. Less back pressure inside the cabinet means we can tune for a stiffer, better controlled driver suspension. We retained the best aspects of our previous design, such as the aluminum center cap responsible for stiffening the lightweight 10” (250mm) cone while adding almost no mass. The updated combination produces considerably better attack and dynamics with greater transparency.

amplifier

Tried and True Amplifiers

The Brains Behind the Brawn

We have retained our signature Class A/B amplifiers used in every generation of Serie T since 2006. Reliability is the key to happy ownership and with some 200,000 and counting of this range leading long happy lives, Serie T/x owners can feel certain of REL’s standard setting reliability. The powerful 300 watt mosfet amplifier used in the T/9x remains an icon with huge reserves of current, massive power supplies but small upgrades are found everywhere. New driver mosfets that open up performance and transparency and new methods for securing the toroidal transformers mean better performance and superior strength.

REL’s legendary High Level Input connection and fast filters are a significant part of the REL story. Connecting via the speaker outputs of your amplifier without drawing any power from it may seem like magic, but the real magic lies in the way the sound takes on a natural character. Unique tuning and special limiters means the T/x range sounds fresher, faster and more dynamic than before.

Standby Mode switch is only included on 220V units.

Wireless That Doesn’t Compress the Sound

Unlimited Possibilities

At REL, we’ve developed a sterling reputation for building the finest sounding, fastest wireless systems available in the industry. We never rely upon digital compression as it results in dull, lifeless sound. Instead, we have perfected an (optional) Arrow™ wireless system so fast and dynamic we’re comfortable encouraging the use of wireless on one channel of a pair of RELs while the other channel may be connected conventionally with cable.

Powerful, Subtle and Sweet!

The 9TX!!!

I am so happy and so surprised. I was a previous owner of a REL T9i. And I thought THAT was the best it could get. But the sound that radiates from this sub is just so unreal that I almost can’t get over it. I’ve place the sub in a corner and installed the Arrow Wireless. I’m blown away.

Certainly didn’t think there would be that much of an improvement from the T9i but there is. Hope this can make sense—it’s subtle but so very distinct. It’s a leap of higher fidelity. A move to a different house made the need for a wireless connection. (Just too far from the audio components). So I inquired about the Arrow and I had my doubts. Really did. I was concerned about lag, and ovderall performance. No lag!! GREAT SOUND!! Oh!! Subtle when it should be, room filling base. But if there are gun shots or rockets fired, it’s as if YOU are shot or the rockets are ZOOMING through my home.

Great, Just Great.

Great addition to my system

I purchased the T/9x after advice from Rel and Mike the owner of Big Kid Toys AV in NC for my Martin Logan Stagei center channel speaker. I cannot be happier. I had no idea how much information comes through the center channel. As a huge Star Trek fan the first movie I played was Star Trek The Undiscovered Country and the differnce when I truned on and off the sub was unbelievable. I added another S812 to make a stereo pair to match with my Martin Logan ESL 11A's and again, WOW! Although, my wife is not happy with the new look of the living room, I think once she hears the difference, even just TV, she will be ok. Adding a sub to the center channel will make a huge difference and you will not be sorry for the investment.

Fully satisfied

I ordered a T/9i based on a REL recommendation at a closeout price just prior to the release of the X series. This was after returning two competitive subwoofers that were just not robust enough to pair with KEF LS50 Wireless II speakers in a 20x20 room. The 9/i performed flawlessly, but I opted to switch them out for the 9X at $350.00 more. I cannot honestly give an accurate comparison between the old and new generation, but notice that the Hi/Lo level adjustment on the 9X is now set at 15 clicks instead of 20 to produce similar bass. In short, the 9X produces amazing low bass, is super fast and accurate and really enhances the capability of the KEF LS50 Wireless II. REL support was appreciated in that they helped me with the app settings on the KEF's and turned around a full refund of the 9i immediately.

I usually retain packing boxes of purchased equipment in case of a need to return, but the KEF and REL boxes will be kept only for moving purposes

Amazing power and quality in a small package

I installed this sub in a large room with high ceilings, to use for both 2-channel listening with stand mounted speakers (ProAc Response DB1), and as part of a 5.1.4 Atmos system. It's amazing how well the sub fills the space in both contexts; it blends beautifully with my main speakers via the high-level input, but also packs a huge punch with the LFE channel in movies. I love that I can use both inputs at once, so I get the same bass extension in the main speakers when listening to movies as I do in 2-channel mode, without ever having to use the crossover built into my AVR.

I've heard it can be difficult to get the placement and levels tuned just right, but we had ours going within about 20 minutes, and then only needed minor adjustments after following the break-in procedure. I'm sure everyone's room is different but I can vouch that it's not universally difficult to set up. The results have been well worth the cost, saving me from an unnecessary upgrade to the main speakers or power amp. As many other reviewers have said, the soundstage open up, the imaging improves, and there's a fullness to the sound that helps details come through across the full spectrum. Even at low volumes, the sub just adds this almost intangible level of support that leaves the everything quite empty in comparison when you shut it off. For most of the music I listen to, I'm not looking for house-shaking bass, and the REL stays quite polite. But it's also not lacking with hip hop or dance tracks when that extra thump is needed.

I've read and heard great things about adding a second sub (plus one to go with the surround speakers!), and while I might do it some day in pursuit of "even better" sound, I can say the single T/9x performs wonderfully on its own, even in my large room.

Aside from the sound quality, the build quality is exceptional and provides a look and feel that matches the excellent sound quality. We purchased the Gloss White and it feels right at home in our modern living room. Where some folks want to show off their gear, we prefer ours to blend in a bit more, and the white option fit the bill. From the pictures—and perhaps due to it being the biggest one in the line—I expected something a little larger than it is, but it has a nice low profile with a pretty manageable footprint.

If I had any minor complaints, I can really only find two. First, aesthetically it would be cool if the grill didn't float off the front face so much, however I'm sure there are good reasons for it being the way it is (like preventing it from rattling). Second, the 110 volt version for American market doesn't have any kind of standby functionality. I haven't measured idle power consumption but plan to measure it and put the unit on a smart plug if it's drawing too much power.

But those two points are quite minor in the big picture. These are special subs and you really can't go wrong trying one (or more) in your system.
