Hi Everyone,

i just picked up a sub a lava lsp12 to be more specific.

I was on a restricted budget and found this for just $140 so i decided to give it a shot.

 

I'm having a real weird issue.

 

Basically, i tried setting up my sub to my pioneer vsx-1123-k receiver which is a 7.2 receiver.

 

I have 2 klipsch f-10 speaker as my main left and right, and 5 bose satellite speakers as my surround speakers. 

In my entertainment setup i also have my rogers cable box setup and my ps4... all going through the receiver and outputting to my projector.

 

When i plugged in the sub with a subwoofer belkin cable i get no bass just a humming noise... i called the manufacturer and they said to open it up and check if something was lose inside, but everything seems ok.. 

 

Now.. this is where it gets weird...

I tried using it upstairs in my living room... and i set it up on a vsx-523 pioneer receiver... and same issue except this time the humming was very loud!

 

So for some reason my head told me to try a different plug in the room... and bam! the sub was pounding like crazy!

So i thought maybe i did tighten some wire up.. but no i bring it back downstairs and same problem dim hum and no bass output at all.

 

any idea what the issue may be?

Some tips on this article as to why it may be humming...

 

If it does not hum with anything plugged into it, chances are the unit itself is fine. So it could be a grounding issue somewhere. That article has a lot of suggestions.

what do you mean if it does not hum with anything plugged in? That if i just plug it in to a power source without a cable going to the receiver?

Also regarding the article i tried completely unplugging the cable box from the power source... but sub still not outputting anything...

Could very well be the ring main in your house. Electrical interference is 90% the issue when audio hardware hums or crackles.

what do you mean by ring main?

I just had the basement finished and we re-did the electrical and put in a new eletrical panel and fuses and all that stuff... could the issue be coming from there?

Exactly that. Most houses (although i am in the UK so could be different for you) have several rings that power different parts of the house. These are then fused separately. The ring you're plugging in to, or even the house main, maybe leaking. Causing interference.

ic so basically the explanation for this is that.. the sub is good... since it worked upstairs on one of the outlets... so it's just a matter of figuring out grounding issues....

 

now because the basement is finished... is there any work arounds other calling an electrician?

 

Does this also mean that it is a good sub and not a faulty one?

How handy are you with a multimeter? (Get the same electrician that did it in the first place to fix the issue)

    • AI is indeed eliminating jobs, and Oracle just proved it

      AI is the justification that company administrators use to lay people off; it is not the end all, be all touted in the media (many of whom can't tell a microchip from a potato chip). Greed is main driving factor behind its adoption; the other is remaining relevant in the face of competition from other entities.

      Firefox 152.0.2 is out with fixes for performance, translation, and cloud storage services by Taras Buria A new bug-fixing update is now rolling out to Firefox users in the Release Channel. Less than a week ago, Mozilla fixed crashes on Intel Raptor Lake processors with version 152.0.1. Now, Mozilla has prepared yet another set of fixes that address problems with localization, playback issues of certain MP4 files, and performance issues on website that perform various encryption operations at once. Here is the full changelog: Firefox 152.0.2 is now available for download from Mozilla's FTP. Existing installations will get the update over the next several hours. The latest version will also be available soon on the official website, the Microsoft Store, and Neowin's Software page. You can find Firefox 152.0.2 release notes in the official documentation. In case you missed it, Mozilla released Firefox 152 earlier this month. The latest feature update brought reworked settings with a more streamlined user interface, JPEG XL support, new features for Private mode, a new way to mute a tab (just type "mute" in the address bar), and many more. You can find the complete changelog here. In other Firefox news, Mozilla recently published its roadmap, where the company detailed the upcoming Nova redesign and other features it plans to implement. Mozilla wants to make the new user interface easier to navigate and more modern, with a heavy focus on its privacy tools, such as its built-in VPN. If you are curious, you can already enable the new UI as described here.
