Purity Reimagined

Stunningly Simple

Simplify, Then Add Lightness: Simplicity is its own reward and T/5i reduces the classic cubic sub to its bare essence. A single, high quality AlloyFibre™ composite driver and down firing orientation produces maximum coupling with the floor and eliminates the need for a grille. T/5i is the purest expression of REL.

Reinforced Simplicity

A 360-degree Upgrade

When we upgraded our drivers, we were forced to redesign outward. The lovely cabinets grew over its predecessor due to thicker cabinet walls and improved bracing. Why? Because the additional speed and impact of the new drivers requires greater control or the benefits can be lost before they get to the listener.

driver

Faster & Deeper

Swift

We began by updating our classic 8” bass engine to reduce mass, while greatly increasing stiffness. This improvement led to upgrading cabinet dimensions and wall thickness to better control the deep bass. Additional upgrades extended even into the design of our feet, resulting in greater speed and solidity to the presentation of sound.

The Old Meets New

I'm using my new REL T/5i together with a 30-year old Carver HR-752 receiver, streaming TIDAL music from my MacBook Pro via USB to a iFi Nano Black DAC and an iFi Tube 2 pre-amp, ultimately driving a new set of Buchardt S400 speakers. These components provide modern conveniences with the warmth of yesterday. The REL provides a solid bass foundation that supports a sound that I couldn't be happier with. The depth of the music just wouldn't be the same without deep tones and quick, precise reaction of the REL. A wonderful addition to complete any stereo system. A tip of the hat to another quality REL product.

It's a REL !

The build quality for this price point is awesome.. solid, stylish and bold. I needed The build quality for this price point is awesome.. solid, stylish and bold. I needed a sub to compliment my Klipsch RP-600m's in my small office. I am still experimenting with position but have thoroughly enjoyed it's performance thus far. First sub I've ever owned that is not thumpy or boomy (this is a compliment!). The lows almost disappear to the point where I thought the sub wasn't on.. I was fooled as I tested it on/off.
I emailed REL support prior to purchase and had a great dialogue with REL's Chief Designer John Hunter. Check out some of his YouTube videos.

T/5i Is A Miracle Sub

I am going to tell you about my experience so far with the T/5i. In a word: AMAZING!!! And that was after just a few minutes of music testing.

I own a stereo rig from the 1970s with speakers from the same era. The sound output is tri-amped so I can better utilize an Electronic Crossover Network with the speakers. I was happy with the sound I had, but I always felt something was missing.

Because my rig is 50 years old I and not a modern high-end system I reached out to John Hunter, REL's Lead Designer and Owner, and described my setup. After researching subs in general and REL specifically, I asked him point blank: would a REL sub help improve the sound of my vintage system. John was straightforward in his reply: Yes!

After much discussion, I settled on the T/5i. Once delivered I integrated it into my audio room and chose the high level input to see how it would integrate with the older equipment.

The sound output adds a solid foundation to the sound picture that was not there previously. From my discussion with John I knew to expect more of a bottom end. And there is. But John said the sub would also open up the mids. And boy does it ever! The T/5i adds clarity and presence to the lower and upper mids that wasn't there before.

The T/5i makes my 1970s-era speakers sound so much better than they ever did on their own. There is so much more music being presented - instruments in the vinyl recordings that I had never heard. Until now.

The T/5i was the single best purchase I have made to improve the sound of my stereo system. The T/5i packs a big wallop and makes my 50-year-old vintage stereo system sound like a modern day high end rig.

If the T/5i can do this for me, think of what it could do a high-end rig!

Thank you so much to John and his team for taking time to talk me through what REL subs is and what their subs can do. I’ll be recommending REL subwoofers to everyone I meet who is interested in great sound! And you can be sure I’ll be back when it’s ...

This the best sub I have ever had in my home

I have owned my T/5i now for over 3 years in two different living rooms. I downsized then upsized a little bit. I was afraid the T/5i would not keep up in my new home. So I might need a second one :). Well the little guy does just great in a room that is almost 3 times the size of the last. The problem is my wife could tell I didn't really need a second one :(. I use it with Vandersteen VLR Wood bookshelf speakers and Dynaco solidstate gear that I've completely rebuilt with highend parts/wire and several mods. It sounded HiFi without the T/5i now it's Highend with it. Wish I would have thought to turn the level on it down so I could have convinced the wife we needed a second one ;). Awesome product that exceeds all expectations.
