marknicholson Posted October 19, 2019 Share Posted October 19, 2019 Hi everyone, I just purchased a Klipsch Sub (R112SW) from Crutchfield and hooked it up today. This is the email I sent to customer support. If anyone has any ideas, please let me know? Dear customer support, Got my new sub ( order #46550156) yesterday evening and hooked it up this afternoon. I first unhooked my older Velodyne DLS 3500 sub and then connected the new Klipsh R112SW. However, almost no sound emits from the Klipsch sub woofer and the sound that does is buzzing and distorted. The only way to minimize/eliminate the buzzing / distortion is to turn the sub lowpass to the 50/90HZ number and also turn the Level control to minimum. Then of course, the sub is making no audible sound. The Klipsh is connected via the L/LFE (white) connection and Sub Out #1 on the TSR 7850 receiver. I have set my receiver Yamaha TSR 7850 sub woofer output settings to zero (0) DB gain. This is the exact settings I was using for my old Velodyne DLS 3500 sub. I have tried a new cable (monster) RCA sub woofer cable with no improvement. The Klipsch phase switch is set to 0, however I have tried 180 with no improvement. The power switch on the P112SW is set to (Auto), however (On) does not yield improvement. (Stand by) works as expected by turning off the sub. The LED power indicator on the sub is working. The power 110V plug connection appears to be slightly loose in the socket, however the sub is receiving uninterrupted power. All connections are Cable Logic - Sapphire series (HDMI) & Monster - Silver Advanced series (RCA). My wife and I only listen to audio from cable TV and surround sound movies. Only on very rare occasions do we listen to music. My system generally consists of: 75" Qled Samsung TV (about a year old) Yamaha TSR 7850 Receiver (about a year old) Klipsch KG4 Floor Standing Fronts - Legacy Loudspeakers (purchased in 1985 +/-) they are fantastic. Klipsch SC5 Center (about 5 years old) Klipsch Pro18RW In Wall Rears (about a year old) Klipsch R112SW Sub (one day old) which appears to be defective? Velodyne DSL 3500 8" sub (no longer used in main living room due to larger / newer replacement Klipsch unit). The Velodyne DSL 3500 is now used on our office PC surround system. (at least 7 years old) Our other PC workstation has the Klipsch THX Promedia 2.1 speakers. (The pro media THX speakers are ridiculously great sounding). Please let me know what I can do to resolve this problem?

Amstaff Posted October 22, 2019 Share Posted October 22, 2019 Hey Mark - I can't really help here as I don't have on those subs. It sounds like you did everything right. Does this sub have a volume control on it? Is it turned up? What has Crutchfield said? They are normally pretty good in the customer service department. Good luck.

CECAA850 Posted October 23, 2019 Share Posted October 23, 2019 If your old sub worked properly with those settings and connections then your new one should as well. Sounds like an amp issue. Quote Link to comment Share on other sites More sharing options...
marknicholson Posted October 31, 2019 Author Share Posted October 31, 2019 Thank you for the replies. Crutch-field replaced the sub and the new one works perfectly. Great, hard hitting bass. I also replaced my old SC-5 center with an R34C. It sounds great as well. My next upgrade (within my budget) is replacing my KG4's with R-820F's. Thats what I can afford. 2 Quote Link to comment Share on other sites More sharing options...
