  • Performance, Quality, Versitility and Engineering Excellence.
Color: High Gloss Black
I have been in audio for the better part of 50 years. I now have experienced something I thought I never would. Seemless integration of a sub into my 10x11x8 room with performances heard in the recorded acoustic space vs coming from boxes in a room. The sub choser matched the T/5X to my Focal 906's and room size spot on. Placement turned out to be centerish due to a room mode from either corner as it is sparesly furnished only having a back wall treatment. REL says to start in the corner and go from there. I tried the Tzero MkIII to get a taste of REL but it simply didn't have the output. Return was easy and unquestioned. With the T/5X using high level connection I followed the break-in video and yep, performance improved, volume went up so I turned it down, 15 +/- 3 clicks up on the crossover and the volume, just like their video said most users end up at. It is set on carpet, no isolators, no messing with their calculated clearance and..the floor literaly moves in waves when material calls it out rather than emphasize it to my ears. Sub bass within limits from an 8" properly designed piece. I love that experience. Vintage system is Akai Tape deck, Rega Saturn CD player, Sonic Frontiers SFL-1 Preamp, Conrad Johnson Premier 11A with Teflon Caps, Nordost Blue Heaven ribbon interconnects, Cardas Quadlink 5-C into amp to smooth things out a bit, then Nordost Heimdall 2 ribbon cables to bring it to the Focals bolted to the Aria S900 stands. The class AB amp has large heat sinks that never get too hot even after hours, stays warm in idle but always ready to go. I like all the options I have with this sub, Arrow Wireless port, High Level and .1LFE option combined if I move it to the movie system, excellent informational vidoes on their web site. Only thing, has no standby switch and the back light is too bright for me but soothingly colored. Fit and finish are flawless, so a beautful addition as well. I plan to try dual T/5X's in the future as properly balanced bass even to 32 Hz is addicting with reproduction felt below that..though have not measured it. I don't want DSP or other electronic aids in the signal path, neither does REL if it is engineered right from the beginning as they have done with this new product to my ears, in this room. ... show more

  • Phase-linear sub
Color: High Gloss Black
You may have heard REL talk about their 8ms filter. I suspect they're using FIR filters to time-align (and EQ) their subwoofer. This is all well and good, and indeed the group delay of a sub can make it challenging to integrate. Unless you locate the sub right next to the listener, and your mains are at least 8ms farther away than the sub, youll get a bit of time distortion. Whether this is audible is another question, and how good it'd sound with treatment is another. I ended up returning as without treatment a sub is an uphill battle, integration aside. Great build quality. Very powerful sub. Doesn't go as low as the Rythmiks and doesn't have their adjustable phase knob, but again the REL will be more time-aligned (despite the 8ms group delay). ... show more

  • Tight, small footprint and not too much "sub" if you're looking for audiophile quality sound.
Color: High Gloss White
Using the high level speaker input, in a small 10 X 12 room, REL is a good step up from a speaker manufacturer branded sub. Whatever you do, dual subs should be what you shoot for, so whether you buy one and then the other, or both at the same time, you're leaving low end detail and separation on the table if you don't. ... show more

  • Not sure if this was a returned item
Color: High Gloss Black
I dislike writing bad reviews as I am an Amazon seller myself. However, upon opening the outer box of this product, there was no inner box. For such an expensive item, I would think there would be an inner box because they made such a conscious decision to make their instruction manual and product so visually appealing. When I plugged the device in, at 3/4 of the volume, the speaker sounded cracked. I could not listen to it at any range over 3/4 of a turn. It was terrible. My thoughts are that this was a returned item and it was sent to me without any type of QA - especially because it did not have an inner box. I think it was a returned item and they just boxed it up thinking that they could sell to a sucker. I have 5 kiplsh ceiling speakers and they had better bass... Layer in the day, I went to Best Buy and explained that this subwoofer sounded blown and the tech was surprised until I mentioned that it did not have an inner box. I am still searching for another subwoofer. I may edit my review if I find some kind of solution even though I returned the product the same day I received it. ... show more

  • Way better than anyone tells you
Color: High Gloss Black
I have dual T5x's. Based on recommendations that this would not be powerful enough. Let me be the first to say, this is as much as any 10" I have heard. I am not disappointed with the dual setup, but I could have easily used just one. The unique way the REL's aquire the signal is also very good. It really helps blend the low end into the music. Also, it helps with voicing. I have an amp that is not too heavy on bass. Vs another that is heavy. The special REL cable allows me to capture that voicing. So many other subs are boomy, this one is tight and accurate. The dials are also indexed so little changes can be made accurately. I looked at other brands that have apps and such, but really once the subs are set I almost never touch them. So on the fly adjustment was not that important to me ... show more

  • Pound for Pound Champ
Color: High Gloss Black
This gorgeous, well-crafted little gem is perfect for my smallish listening room and pairs seamlessly with my Wharfedale Linton's. A musical sub is rare, one with this fit and finish under $1k as well is a unicorn. Bass is deep, articulate, and tight. Likely the long term reference for me.

  • REL. That says it all.
Color: High Gloss Black
Bought this (T5x) for a system I am putting together with Magnepan LRS. After doing my research then asking the pertinent questions with REL customer service I landed here. I am as satisfied as I could ever imagine. They are one of the first companies that didn't immediately try to up-sell me and instead took in all my factors and wants and suggested this. The fact that you can order it, try it, and if you don't like it, send it back for exchange or refund says a lot about a company. I will not be sending mine back, I will be ordering a second. ... show more
