TBird1961 Posted December 14, 2020 Share Posted December 14, 2020 I'ver lost the subwoofer in my home theater system. My subwoofer is a Klipsch R-112SW and my receiver is a Yamaha RX-A3030. I've attached photos of my connections. In my receiver setup I've checked that my subwoofer is in "Use" "Normal" mode and my playback is "9 ch sterio". My subwoofer power led is lit and I've tried both "on" and "auto" and phase "0" and "180". I've tried to run the auto speaker setup but no sound emits from the subwoofer when the test signal sounds are to be emitted. My RCA cable seems to test for continuity and I've tried a second cable as well. What else can I do at this point? 1 Quote Link to comment Share on other sites More sharing options...
billybob Posted December 14, 2020 Share Posted December 14, 2020 Not sure you checked the fuse Welcome and there are threads on the subject here. Check the sub forum where you posted. Thanks! Quote Link to comment Share on other sites More sharing options...

wuzzzer Posted December 14, 2020 Share Posted December 14, 2020 The 112 and 115SW subs are notorious for amp failure with little to no warning. Quote Link to comment Share on other sites More sharing options...
Peter P. Posted December 14, 2020 Share Posted December 14, 2020 You sure you're connected to the correct output on the Yamaha? Looks like you're using the "PRE OUT" "Front" connection. Does your Yamaha have a subwoofer output? Quote Link to comment Share on other sites More sharing options...

Looks like you're using the "PRE OUT" "Front" connection. Does your Yamaha have a subwoofer output? That's the subwoofer pre out for their receiver. It has a separate "front" and "back" subwoofer pre out. Quote Link to comment Share on other sites More sharing options...
TBird1961 Posted December 14, 2020 Author Share Posted December 14, 2020 I did not check the fuse, I do get a green power led when plugged in to power. I get absolutely no sound out of this, no feedback, no nothing. Crap. Quote Link to comment Share on other sites More sharing options...
Amstaff Posted December 14, 2020 Share Posted December 14, 2020 I have the same receiver. I only use 1 of the sub pre out an connect it to the LFE input on my sub. The receiver supports 2 subs Did it work connected like this? The 2 sub pre-outs to one sub? If your amp is indeed dead - either fix it or buy a new sub (I would suggest non-Klipsch).

CECAA850 Posted December 14, 2020 Share Posted December 14, 2020 The easiest way to get your bass back is to disconnect the power cord from the wall. Next remove the subwoofer.RCA cable. Slide the subwoofer out of it's current position and put an SVS in it's place. 3 3 Quote Link to comment Share on other sites More sharing options...

Peter P. Posted December 15, 2020 Share Posted December 15, 2020 Prove the receiver output you're using is actually producing a signal. I'd try connecting the sub to the PRE OUT connections in the photo, just to verify there's still no output Quote Link to comment Share on other sites More sharing options...
Max2 Posted December 15, 2020 Share Posted December 15, 2020 Turn the sub on. Unplug the RCAs from the AVR while they're still plugged into the sub. turn sub up halfway. Tap the ends of the RCA end with your thumbs. No sound, its likely dead unless it has a fuse. You can also plug anything with RCA's outs into the sub to check it, just turn the sub down to start with. Quote Link to comment Share on other sites More sharing options...

Sunnytex Posted December 5, 2022 Share Posted December 5, 2022 I know its 2 years late but maybe it will help someone.I had the same problem until i found out it was a setting you had to turn on. You have to turn on the "Extra Bass" Setting in the Manual Speaker Configuration Menu of the Yamaha. Quote Link to comment Share on other sites More sharing options...
