REL Acoustics Tzero MKIII Powered Subwoofer – 6.5-Inch Down-Firing Driver with Class D Amplifier, RCA Inputs, Compact Design for Home Theater, Stereo Systems, and Surround Sound – Gloss White

I waited over a month to write this review so that I could have it set up perfectly. And perfection it is!First, let me tell you about my space and setup. I'm using the REL in a family area of an open kitchen. So, it only has three walls. Each of those walls is about 12 feet. I've included pictures of the space for this review. I have the sub beside the couch - kinda in a corner. My receiver is a Marantz SR6012 and my main speakers are Sonus Faber Cremona Auditors.The build quality of the REL is outstanding. It's as hard as a rock and the finish looks like the paint is still wet! The controls are super cool looking.So, this setup is not actually my main listening system. I just set this up for my casual TV area. But i have to say that it's becoming my main listening system! My main system has a vented subwoofer and while it is large and powerful, it lacks the musicality and accuracy of the REL. I have heard people talk about this tradeoff and now I know what they are talking about. I will never buy a vented sub again. My system with this REL sounds UNBELIEVABLE! I can't stop listening to it! The realism is insane! The REL has MORE than enough punch for this space! I'm actually glad I didn't get a bigger sub as I don't think it would have been as compatible with my small sized mains.What can I say bad about it? Not much. The only thing I have noticed compared to my main is that the super low end is cut off. I notice it on a couple of songs. But I really hesitate to mention this because this REL seriously kicks! I get the full "velvet hammer" with the REL in my space! And there is plenty left in it. I have the receiver setting for the sub attenuated -3db.I should also point out in my setting that the listening is really optimized for one seat on the couch. From the "golden chair," the system sounds insanely good! But even moving to the other side of the couch, the bass falls off noticeably. And in the rest of the kitchen, the bass is unremarkable. But I think this is more of a function of the positioning of the subwoofer and not any weakness relating to the REL. However, I do believe that if I moved the sub out to the open, it would have a tough time delivering the velvet hammer to the whole family room and kitchen. But that was not what I was looking for. I was looking for and got an amazing sub for watching tv or listening to music from a few listening positions.I am so impressed with this product. I will never buy anything but a REL sub. I am in the process of deciding which one to get for my main area now. The musicality and accuracy are astounding. It blends seamlessly with my mains. I don't even know it's there. Never boomy. Always tight. I wish you could all hear my system! I'm so proud of it!!! Five stars for the REL!!! You'll love it!!!!

The Rel subwoofer rounded out the sound of my JBL 4312G speakers. It added another layer of sound and picked the lower base that the speakers missed.It is amazing! Well worth the price.

As a rule, I'm not a fan of really loud bass; I like a balanced sound. I've enjoyed my magneplanar speakers (Magnepan MMG) for years without a subwoofer. But this really blends nicely with them, and adds a richness to the sound. It's also easy to hook up.

Got a pair of this for set them on top of my REL G1 subwoofer. The new pair of REL Tzero MkIII immediately post me a big problem -- unable to successfully connect its supplied high level signal cable (Neutrik male to Neutrik female) to the sub. I am an experienced REL user. After hours of struggling I just can't rotate the Neutrik 100 degrees clockwise to complete the connection. I hate to return these sub. So I pull out my G1's cable in an attempt of connecting Tzero mkIII. With a few struggling it finally went in and the sub can play bass. After, I try to put back the new cable, it just won't connect at all (both Tzero mkIII same). A few back and forth proof new cable has mechanical tolerance issue. They need replacement. Unfortunately I was unable to use Amazon to contact the seller. I wish to resolve this issue rather than returning both Tzero mkIII.

Just what my ScanSonic MB1-Bs needed. Really fills out the bottom end without being aware of it. Fills my 14x18x10 room beautifully. Mainly a jazz listener and some 60's/70's rock. T5x isn't necessary at all for me. Recommended!

I paired the T/Zero with a pair of Vanatoo Transparent Zero speakers and I am blown away by the quality of the sub. With a Toslink connection and a decent DAC from my iMac, now my Sony XM3 headphones sound subpar. I have the sub in a room just under 200 sq ft, and it fills the room with sound!! Highly recommend

Have it in my living room connected to the computer stereo with my ML 15s. I decided to replace it with ML Dynamo 700W, just overkill for me. . This sub is well anough for 400 sq. f. Just try it, you will not want to send it back. Make sure that you use REL`s high input connection, it makes all magic with the sound.

Rel is the Lambo of subwoofers. Even their smallest sub packs enough punch to satisfy the home theater enthusiast and the refinement to please the most discriminating audiophile. Read the manual, follow the setup instructions, and you'll be rewarded for your efforts in spades.Only problem I had was with the high level cable. After hooking it up to the speaker terminals I plugged it into the Rel, but neglected to turn the connection on the sub until it clicks into place. Over the next few hours I plugged and unplugged the high level connection, reconnected the speaker cables, until I finally figure out the issue and turned the high level connector until it clicks into place. I was afraid I would break it, as it didn't turn easily.
