    Looking for help from the community of smart people (this forum).

    I’ve been having issues with my in-home stereo system subwoofer.

    About 4 months ago, my two-year old Definitive sub (higherish-end consumer brand) began to have a constant low rumble. It’s doesn't start until a signal/sound is sent from the stereo and when I unplug or turn off, there’s a pop almost like a static discharge.

    Its connected to my stereo via an RCA cable.

    It seems like more of an electrical issue rather than a blown speaker since it’s constant even when the volume from the amp is turned all the way down. But again, it doesn’t start until there is signal going to the speaker. Once it starts, it won’t go away until I unplug or turn the subs power off.

    I’m not too interested in getting a new sub as this thing wasn’t cheap and it’s fairly new.

    Thank you in advance for any help!!!

    I'm not sure if this is your issue but a couple months ago my sub was making a hum noise even though no bass was coming out of it, so I decided to take it apart and clean all of the dust bunnies out of it. After putting it back together and testing no more humming :notsure:.

    Have you tried a using a different out from the receiver?

    I’ve had a sub channel go bad on a receiver before and it started sending a dirty signal that led to an electric hum.

    Since the sub is relatively new, it may be worth diagnosing the signal?

    Thank you. I will give that a try!!


    I think there is only one sub-out signal but I will double check that. Thank you.

    Might be worth trying a new gold plated RCA cable. Or, try using electrical connector oxidation cleaning spray on the jacks. Sorry, the brand name escapes me but they have it at Best Buy. Sometimes oxidation is enough to affect the ground and cause humming and popping. The fact that it's constant makes me think it's the connectors or the cord itself.

    It’s Best Buy’s/magnolia’s “high end” brand. I’ll give that a try.

    Contact Definitive and tell them exactly what it’s doing. They shipped me a new amp for my super cube 1 after describing a very similar issue. I don’t remember what I paid for the new amp but it wasn’t bad.

    It will be the amp board in the sub... the hum is a classic sign of that component failing.
    Go with a Sunfire sub if you can't get it serviced.

    It could be a ground loop problem, which is a difference in ground potential between the receiver and the subwoofer amplifier. The rca cable carries the current and can create a hum. Check for a good ground on the circuit with receiver and the circuit with subwoofer, or better yet plug them into same good grounded outlet and see if it goes away.

    When the subwoofer is humming you could also try unplugging the rca and see if the humming stops, if it does this could indicate you may ground issue. Or it might just be a sign of a failing amp as well. For a relatively inexpensive replacement...if you go down this route I highly recommend BIC Acoustech Pl-200 II, retails less then $300 and has very impressive bass.

    If I unplug the RCA, the hum doesn’t go away. Makes me think it’s the sub.

    I’ll try calling Definitive in the morning and see if I get anywhere.

    If I don’t get anywhere, I’ll try some of what has been suggested above.

    Called Definitive, they said the amp in the sub has gone bad. Unfortunately, I don’t think I purchased it from an authorized retailer so the warranty is void.

    I purchased it on Amazon from “the audio video guy” or something. Definitive is reviewing the “case” and will let me know.

    There are a ton of good subs for not s lot of coin. SVS, velodyne and mirage all come to mind. If you want some help let me know. The used market is your friend......happy to give some advice as I have installed dozens of home theaters on a wide range of budgets.

    Definite Technology should be able to take care of you. I use a lot of their speakers throughout my home. Very happy the way they sound. If DT doesn’t fix it, see if they will give you a list of venders who will.

    Other than the fact that I had to reach out to Definitive to follow up, I am very happy with the outcome.

    The seller I bought the speaker from originally was not an “authorized retailer” for Definitive so technically, I was SOL. If he was, they would have sent me a brand now speaker.

    BUT, when I called them today to check in, they apologized profusely for not calling me back with an update.

    And now, because of their mistake in not contacting me, they are sending me a new amp for the speaker, free of charge.

    I love companies who take care of their consumers. Definitive is 5 star in my book.

    Thank you all for your input on other speakers. I was about to make another purchase but good thing I didn’t.

    Sounds like a capacitor going bad. Don't use it anymore and look for dampness around the caps in the power supply, get the size of them and replace them.
