PSW110 Issues: Static , Heart Beat woes

My PSW 110 (Out of Warranty) recently started to make a pulsating noise. I have swapped the power cable and tried it on a isolated circuit in the house. Also input cables have been swapped and tested. The sub will do this without any input from the receiver. The only way to silence the sub is to remove the power cable. Any thoughts? Is the internal amp faulty? Seems I'm not the only one :-(

  • Since my home theater room had a area built around the spec's of this speaker I'd like to have the same sized unit. Is there a current model Polk powered sub that does Not suffer from what looks like a faulty amp issue?

    The PSW110 is 14 5/16" W, 14 11/16" H and 17 1/2" D the PSW108 is 14" W, 14 7/16" H and 16 1/8" D and seems to have a good service record.

    Do you have any info to back up the "good service record" claim? I'm hesitant to invest another dime in Polk audio.
    Upon further research I can find at least 40+ instances on the web of my exact issue. Amazon, Crutchfield, AVS Forum, Tomsguide, Polk forums ect. The Amp unit in these sub's (and other models with this Amp assembly) should have been recalled.

  • I have been in touch with Gil in their service dept. I will ship them the amp and see what they say. In the construction of my home theater the built in's were customized for my all my Polk speaker components. I can't wait to have it up and running again!

    Gil's a good guy, he'll help you out.

    I'm also having the same problem. I Googled "PSW110 heartbeat" and it seems LOTS of others have the same problem. I've been using Polk speakers for years and this is the first problem for me.

    Hello,
    Welcome to Polk's forum, sorry you're having a problem. The best approach is to contact Polk's CS department at: 1-800-377-7655 select option 1. Have the sub's serial number and date and place of purchase handy when you call. They'll take care of you.

    Thanks a bunch Ken.
    I called the # and talked to a cs tech named Mike. I would advise everyone to avoid this guy. He was the rudest cs guy I have ever dealt with. He started shouting at me so loud that my wife came into my office to see what the heck was going on.
    He said EVERY subwoofer brand makes that heartbeat sound.

    I finally asked to speak to his supervisor and he asks "WHY".
    I talked to his supervisor named Kim. What a complete turn around!
    Kim was a VERY pleasant gentleman to talk to. He knew the heartbeat was an issue, asked where and when it was purchased and asked for serial #.
    He then said he would ship a new amp to my house, gave me a confirmation # and said he would email me when shipped.

    My faith is restored in Polk Audio . :)

    Hello,
    I'm certainly sorry there was that kind of situation, but glad Kim was able to help. I'll forward this to the appropriate person, Chet. Again, sorry it had to happen that way.
    Best regards, Ken

    When is that sub going to go away?
  • dgrifoo4dgrifoo4 Posts: 1
    I have had my Polk subwoofer for about 4 years now. It is the PSW110. Just recently, I noticed a humming sound coming from it even when it is not being powered by receiver. I also noticed the power light on the rear seems to turn bright orange instead of green. I moved it to a different outlet and and just plugged it in and I am still getting a humming or heart beat type noise. What could it be? Can someone contact me to discuss?

    Is there a recall on these, same problem I have. A bit annoying. Or do we need to file a complaint with consumer protection agency

    Hello,
    The bass amplifier needs to be repaired or replaced. Assuming you live in the U.S. you would contact Polk at: 1-800-377-7655 select option 1. It would be helpful to have the unit's serial number and date and place of purchase handy when you call. If you live outside of the U.S.send an email to: [email protected]

    After reading the feedback here I was hoping to get some help from customer service but was sadly disappointed. I have a PSW110, and already replaced the amp board once due to the dreaded "heartbeat" at my cost in 2015, and now 3 years later have the same issue again. I was told by customer service that the lifespan of the amp is 3 to 8 years which is why warranty covers 3. Been a Polk customer for many years since I bought my first RT-16s, and matching surround speakers. They still sound awesome. Response was not what I expected from Polk.

    It could be a faulty RCA input, at least that's what I think that sub has instead of LFE.
    If that's the case I would just save up for a new subwoofer(Svs).
