Hey guys.Got an issue going on tonight and hoping to maybe get a little help or insight as to what's going on.I have a Onkyo HT-RC270 AVR with a simple setup using the Infinity System TSS-800 speakers and sub. Had this set up a number of years, no issues.Tonight I was watching a movie and suddenly realized I had no bass. I went to check the sub and sure enough, not a peep coming from it.I've checked everything I can think of. I checked the cable at both ends. I tried a different sub connection in the back of my AVR. I usually have the sub connected through the sub's LFE input but even tried the other options, L and R. I power cycled the sub and receiver several times. When the sub turns on, I do hear a "click" inside like something is engaging.The sub is on and getting power and the light is green as if it's getting a signal but still no sound. My AVR configuration is set correctly, sub set to ON, etc. Just no sound. All the other speakers work fine during a tone test.I'm inclined to think this isn't the AVR, but I can't say for sure. This is the first time I have ever had any kind of speaker go out on me. I don't know if there is anything I can do? Anything I can test?The sub is probably about 6-7 years old so I suppose it's possible it just "went out."Looking for any ideas or thoughts on what my issue might be.Thank you!
