Review: They blend with main speakers like magic!!! - 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.
Review: It's a very musical subwoofer unlike bloated bass subwoofer's - I love the REL T/9x subwoofer for music and eventually I want to get another one.
