Review: REL T/5x. Great Subwoofer for 2- Channel Stereo system - 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.
Review: Great sound quality - 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!

## Features

- VERSATILE CONNECTION METHODS: Easily integrates into any home theater or stereo system with speaker outputs or a subwoofer output, ensuring seamless compatibility. Available in timeless black and modern white finish.
- IDEAL FOR MID-TIER SPEAKERS: Pairs best with lower-end 3-way speakers or mid-tier quality bookshelf speakers for a balanced and enhanced audio experience.
- SUITABLE FOR SPACES UP TO 400 SQ FT: Provides deep, pressurizing bass down to 33Hz at -6dB, with the option to use a stereo pair for a more elevated experience or larger listening spaces over 400 sq ft.
- EXPANDED SOUNDSTAGE AND DEPTH: Enhances your soundstage with textural depth that transforms your music and movie experiences into immersive, high-quality performances.
- SEALED SUBWOOFER DESIGN: Features a down-firing 8" driver powered by a robust 125-watt Class A/B amplifier for controlled and impactful bass.

## Questions & Answers

**Q: I own three rel t/5i units; has the shape of the cabinet changed?**
A: The shape of the T/5i's cabinet was not changed at any point during the production run for that model. However, the current T/5x subwoofer does have a larger cabinet than the T/5i, resulting in increased internal cabinet volume. This helps the subwoofer to be more dynamic and powerful in it's output and for it to reach deeper in it's low-frequency extension.

**Q: Does it has two drivers, front and downward?**
A: Thank you for reaching out. The T/5x exclusively features a single 8" down-firing driver, and does not feature a front-firing driver.

**Q: Will this still work if placed on its side?**
A: Thank you for reaching out. The T/5x is specifically designed to have the driver firing down into the floor, and this proximity between the floor and the driver is used to provide deeper and stronger bass extension from a relatively small subwoofer. If you were to place the T/5x on it's side rather than on it's feet, then you would likely find that it does not reach as deep or play as strong as originally designed.

**Q: Does this item work with 220V?**
A: Thank you for reaching out. All T/5x subwoofers sold on our Amazon store are configured to operate at 120V. If your local mains power operates at 220V then the best option will be to purchase the T/5x from your local distributor, or for other options feel free to write in to contactus@rel.net and we will be happy to assist.

### ⭐⭐⭐⭐⭐ Great subwoofer
*by P***N on January 19, 2025*

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!).
