    • One of the best Subwoofers you may be able to afford
Color: High Gloss Black
If you are a music listener, this Subwoofer can be integrated so well with your speakers that it will seem to disappear, and do its job without calling too much attention to itself. (Quite a few cheaper Subwoofers don't do this well.) Or, if you like Bass tones thumping against your chest, this Sub can be tuned to do that too. This may not be the best Sub for you if you plan to use this Sub almost exclusively for TV-movies, since it is not specifically designed to be a 'Thumping & Rumbling' bass that hits you in the chest, which many movie viewers seem to prefer....although the REL T/7x has tuning controls that can do that, BUT...so too can a lot of the less expensive Subwoofers. This subwoofer is very similar to its larger brother, the T9x, which is best for Very Large rooms. The T/7x will work great in most large rooms, but if you have a really large room, you may want the extra large sound of T/9x to shake the walls? Remember, the REL T/7x and T/9x has two speakers, one of them down-firing. The down-firing speaker only kicks-in on the very deepest notes. Many other Subs have one speaker and a Port. The REL's are a particularly well designed Subs, meant to Look Good (in White or Black), no matter how high-end your furniture or sound system may be....within limits of course. If your stereo system costs over 15 grand, you probably can afford an even more expensive Sub(s). For any under 10-grand stereo system, in a traditionally large room, REL offers a model that will hit your sweet spot. I have this T/7x paired with Ohm Walsh 2000 speakers, which generally don't even need a subwoofer, unless you really want to 'Do Deep', with say organ music. But really, to each their own on these sound issues. The REL engineers designing these Subs are sticklers for detail, and you can hear that difference in their musical fidelity and realism. These are highly efficient Subs (unlike most of them), which require less power to drive them, and they use a Class AB amplifier, if that makes a difference to you? Most subs have opted for Class D amplifiers since they tend to be cheaper & pump out more watts, which can be very good at times; but are generally not as transparent as Class A, or AB amplification. For people on a tighter budget, the new Speedwoofer 10S MKII is a good option, very good bang for the buck, for ~$460. Although there is often a waiting list for this Subwoofer. ... show more

    • Strong, very adjustable
Color: High Gloss Black
T7/x Superb. For 60 years I’ve listened to music on a succession of mid quality receivers, amps, and speakers. I thought I was hearing all the music in my records, tapes and digital files. Wrong! There is an entire sub-base text in most orchestral, jazz, r&b and pop music. Even folk and bluegrass have clean licks and lingering tones below the 45hz that most speakers provide. I have a library of 20,000 songs and albums and I’m listening to all of it for the first time again. Suggestion: REL promotes the T9 as the safe choice for a large room. You probably don’t need that. I put my T7/x on an open balcony above a 20 foot by 30 foot great room with 24 foot high ceiling. I can hear and feel the subwoofer everywhere in the house and in the yard. And the T7/x has very effective controls for what frequency you want it to drive and how loud you want it. I set mine to pick up at about 100hz and the gain is about halfway. The gain is clean all the way to 200 watts, but that much gain is less like music and more like a high quality thunderstorm rolling over your house. ... show more

I’ve had 3 different subs before these. They are by far the best. Just upgraded from the Rel T5x’s which are also great, these just have heftier bass and seem to integrate better. Worth the money for me.

    • Perfect!
Color: High Gloss Black
Best subwoofer I've ever heard, and I've heard many. Placed in the corner of the listening room, just like it says in the manual and that's it. Super deep bass for such a small driver. Perfect for all genres of music. It's never bottomed out or overheated. Worth every penny.

    • Succinct punch
Color: High Gloss Black
This sub acts as an extension of my Heresy IV's. It isn't a blow-up-the-world boom stick. Instead it acts as a seamless integration to my tube amp high fidelity speaker system. Love it. I spent a few hours dialing in the setting and placing it in different areas. All rooms are different so if you get one, take some time and listen to the sub from more than one place. ... show more
