Hey everyone! I've done some searching around on these forums and I can't quite find an answer to what my problem is.

I have had a Denon AVR-1912 receiver with Energy 5.1 speakers and subwoofers for awhile, but I have recently noticed that the subwoofer isn't producing any bass (oops). It is connected to a power source and I connected it with a Y cable (connected to the receiver with the left output, as directed in these forums) but I still am hearing nothing. I went through the setup multiple times which includes a microphone that I connect to the receiver so it can check the sound levels, but even that doesn't discover the subwoofer.

Does anyone have any ideas? I can provide more info if necessary. Thanks!

Note: I know the subwoofer works because it is producing heat. Unfortunately, that's about all it does.

If it produces heat, all you know for sure is that it is receiving power. It's status as a working device is questionable.

Find the RCA cable that runs from the AVR to the sub. Unplug it at the AVR end and touch the center pin of the RCA plug with your finger. The subwoofer should produce a clearly audible hum. If it does not hum, make sure that the input gain control has not been turned all the way down.

If it fails these tests, its amplifier is probably history or the driver is fried.. You then have a repair or replace question before you. If it is still in warranty, then you will probably want to repair it. If it is out of warranty you may want to contact the manufacturer or a local elextronics shop and enquire about repaiing it. If it cost you much less than $200 you may wish to dustbin it, because it will cost more to have it inspected prior to actual repair than it is really worth.

First tip: skip the Y-connector and hook-up sub to receiver via and RCA to RCA cable directly.
