Drewski Posted August 19, 2018 Share Posted August 19, 2018 Hi Everyone, I have an R-112SW hooked up to my AVR using LFE. When watching regular scenes with little bass the sub performs as normal. When it gets too intense or very deep bass it cuts out. If I unplug it for 15 seconds or so and plug it back in it powers back up and works fine until another scene. Has anyone experienced this before? Any suggestions. I purchased the subwoofer February of 2017. I am not sure if it is still under warranty. Thanks, Drewski Quote Link to comment Share on other sites More sharing options...
jjptkd Posted August 19, 2018 Share Posted August 19, 2018 The amp could be getting too hot or overdriven and the circuit protection kicking in, have you tried dialing it back a bit to see if it keeps happening? Might be time for a second sub or possibly a larger one if the 12 can't keep up. Quote Link to comment Share on other sites More sharing options...
Drewski Posted August 20, 2018 Author Share Posted August 20, 2018 (edited) I have the gain about half way and it still cuts out. I can lower it a bit. My seating area is 12x14 the highs and midbass come through clear and the bass is deep enough when the sub is working properly. Is the gain still too high? Here is my 5.1.2 setup : LR - RP-250F LRA - RP-140SA C - RP-250C SLR - RP-150M SW - R-112SW AVR - Pioneer Elite VSX-LX301 Source - Oppo UDP-203 Edited August 20, 2018 by Drewski Quote Link to comment Share on other sites More sharing options...
garyrc Posted August 20, 2018 Share Posted August 20, 2018 Many subwoofers have a protection circuit that will turn the sub off if the SPL gets too high. I once asked a Klipsch engineer if they were fast enough to provide fairly complete protection. His answer, "Some people can blow out anything." In your case, you should call Klipsch customer service and ask them, since your subs might be under warranty. 1 Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted August 21, 2018 Share Posted August 21, 2018 What is the level on your subwoofer output in your avr? Quote Link to comment Share on other sites More sharing options...

They are sending a replacement amp for the unit. Seems to be a common thread on this forum. I wonder if I just got one from a bad lot.

Hopefully that will get you fixed up and it will give you years of trouble free service. Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted August 23, 2018 Share Posted August 23, 2018 If you have issues with your new amp, it may be your signal clipping in your AVR. Bump it down and then bump your sub amps gain up to compensate. Quote Link to comment Share on other sites More sharing options...

I'd wait and see if the new amp fixes everything prior to making any other changes. Normally if I'm having any type of problem that involves troubleshooting, I change one variable at a time then retest. 1 Quote Link to comment Share on other sites More sharing options...
Drewski Posted August 27, 2018 Author Share Posted August 27, 2018 I just received the new plate amp and installed it. After some basic testing, the cutting out does not occur anymore. Guess it was a defective amp. A+ to Klipsch Support for sending this out so quickly. Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted August 28, 2018 Share Posted August 28, 2018 Good deal. Glad to hear it's fixed. Quote Link to comment Share on other sites More sharing options...
