Description

T/5x’s mission remains the same: make remarkable bass far beyond its modest size, do so in a way that complements every interior’s style. Perfect for small and medium rooms, T/5x seats perfectly into any décor. Floor-firing is part of its secret; bass energy strikes the floor and spreads uniformly throughout the space making it perform like a larger model. Featuring an 8" front-firing long-throw steel chassis driver, 10" down-firing passive driver, and a 200-watt Class A/B amplifier. Finally, 5 hand polished coats of lacquer in your choice of High Gloss White or Piano Black add luster to the softly rounded cabinetry.

Awesome sub

    • Great subwoofer
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!). ... show more

    • Great sound quality
Color: High Gloss Black
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! ... show more

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.

    • 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

I looked on the Internet and found many other reviewers with the same exact complaint unit does power is on and has the faintest ever output, but there’s something clearly wrong with it.
