- REL T/9x 10-Inch Powered Subwoofer – Sealed Design with Class AB Amplifier, RCA Inputs, and Deep Bass for HiFi Stereo Systems, Home Theater, and Surround Sound – High Gloss Black Finish

This sub is the best blending sub I ever had. With barely any efforts this thing blended with my mains. Can't tell the sub is playing. They sound very clean and detailed. I'm not even using the hi level input REL recommends. Using the low level RCA and they sound great. The only bad thing is when playing loud they can vibrate and start walking. But don't care about that because it sounds amazing. I will be getting another one to have a stereo pair. If you are planning on playing at very loud levels I suggest getting some double sided tape and tape the feet down to floor. I believe on rugs you wouldn't have that issue.

I love the REL T/9x subwoofer for music and eventually I want to get another one.

excellent sound, with good connection options. Build quality is nice too.

Sound and Build quality are my favorite attributes of this product. The accuracy is so good. I wish I could cross it over lower but I worked it out with the room. Use the REL room sizing tool to help get the right one for your room so you do not overspend.

I love the abilities to dial this sub in, tremendous amount of sound coming from this product, I have it paired with 2 Klipsch forte 3 speakers and a 200 wpc class A amp, it's unbelievable how it improved the bottom end and also the mids and highs are more accurate.

The REL T/9x subwoofer is easy to set up, integrates seamlessly with your speakers, delivers tight extended base, and looks terrific in your living space.

Got some help and then silence...... Had a "Hummm" sound at initial hook up when all the equipment was off. Contacted the tech support @ REL a day or two later got someone to email me back suggesting move this, hook up this, run wires this way and that way. So I did all the things and it has never has it quit gone away. So I tried contacting tech support again and have not heard a single thing back. The sub sounded great and was expecting to buy another one to have the "full room effect" but the hummmm from one sub drives me nuts to the point I unplugged it and haven't touch it in months. I would say I had it plugged in and in use for 1month out of the 7months. I mark it up as a bad investment. As I cant get any support on this unit.

I did not get a chance to text the performance. But I did unbox the item. The subwoofer looks amazing. I have own about 5 home theater subwoofers. And about 8 car-system subwoofers. So I guess I can describe myself as a bass lover. And the DEL T/9x is definitely on my top 3. I attached several pictures to show different angles, and specs. I hope my pictures would help others. I will review the performance at a later time.
