- REL T/5x 8-Inch Powered Subwoofer – Compact Sealed Design with Class AB Amplifier, RCA Inputs, and Powerful Bass for HiFi Stereo Systems, Home Theater, and Surround Sound – High Gloss Black Finish

The REL T/5x has great fast, tight bass. Fills in the lower register perfectly. Can't see how a good 2 Channel Stereo system can do without a Subwoofer of this caliber. Highly recommend.

I have a pair of vintage AR M1 Holographic speakers, which is a high end bookshelf speaker. I was told years ago by an audiophile friend that they need a subwoofer to really sound right. Finally I did some research on quality subwoofers and decided on the REL T5/x for my medium sized living room. It really completes the sound and makes those speakers sound great. It’s not set to thump like an obnoxious car stereo, just to create a full, lush sound. I couldn’t be happier with this choice of subwoofer. It’s very clean, precise and musical. It helps bring the whole sound to life - not just the low end - like it adds dimension to toms in a drum set, fullness to brass and reeds, overtones of a piano, overall imaging. My stereo went from pretty nice to YEAH! Definitely recommended!

This replaced a broken Velodyne MiniVee, and so far I’ve been very pleased with it. Excellent sound quality, and connecting the high level inputs was a breeze. I especially like how much information REL publishes on YouTube to determine which product will work best, and then once you’ve bought it, how to install and set it up. Their customer support is top tier (hi, Dermot!).

Awesome sub

Was trying out various little subs at the time due to space. Have a Kanto Sub8 and it was pretty good. This REL just did nothing for me. Tried the RCA and also the high level inputs and it never hit. Also tried an SVS which ended up the same way. Cambridge Audio was pretty good. Ended up with a Goldenear SuperSub X, which was way out of the price range but is freaking awesome. The high level input cable stuff with REL is a PITA. I don't get it.

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).

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.

Great product. Awesome addition to my bookshelf system with monitor audio radius and Yamaha receiver. Filled in lower end and opened stage.

Great subwoofer from Rel! High quality build and the bass is excellent and sweet! Perfect match with my system, 5 stars!

Der Rel T5x ist ein super Subwoofer. sehr gute Klang , sehr musikalisch ,keine Einwände !

Subwoofer attivo che conosco molto bene, dimensioni piccole quindi non invasivo in ambiente domestico, potente , molto musicale e dotato di tutti gli ingressi che lo rende molto versatile ......buon rapporto prezzo/qualità.....consigliato.

First 5* obviously goes to REL. What a magnificent little subwoofer. Blends perfectly with my TOTEM SKY speakers (as recommended by REL). I was getting very good base from the speakers alone, and was hesitant in getting a subwoofer. I am now very happy I did. The second 5* goes to the seller: FILTRONIQUE. When I placed the order with Amazon, the delivery was quoted as 7-10 days. I got it the next day. Very well packaged and no hiccups whatsoever. The packing slip had a hand written note thanking me for the order and telling me to call if there were any problems or if I needed support in setting it up. If you need a subwoofer, REL is the way to go and Filtronique Audio in Montreal is the one to buy it from.

Great subwoofer from Rel! Bass blends perfectly with my bookshelf speakers. High level input that Rel's have is a must so it gets the same signal as your front speakers. Can use the LFE input at the same time too. Fast shipping in Canada from the seller Ayreborn. Very high quality product and packaging. Detailed instructions that cover everything you need to know. 5 stars
