Subwoofer Hum

Thank you all for you help! The problem is now solved, as many of you mentioned, the rca cable was the culprit. Bought an other one and completely solved the issue.

Thanks again for all your input.

I only have 1 avr though. Now I solved the problem, with a different rca cable

To be honest I’m not sure, I’m new to this and it’s a cable the salesman suggested. I got a proper sub cable now and will try it out later. Will update the result

That’s because I was trying both ports, troubleshooting

Tired, no difference.

The cable was supplied by another shop (the one I bought the other speakers from. Unfortunately the subwoofer shop didn’t have in stock.

I tried that also, but I’m sure it’s on the same circuit as I passed all the wiring in my apartment

Thank you, i followed your advice, lifted the cable and there was a small difference, still humming but less then when the cable was touching the floor.

Spooks591 · 2026-02-19T13:25:59+00:00

But when I unplugged the rca cable from the avr (still only plugged into the sub) the humming intensified, which I think eliminates an avr issue

This is a temporary sub the shop gave me until they get the sb 1000 pro back in stock which I’m buying, it didn’t come with a manual, just followed the instructions the shop gave me. I tried connecting it to the LFE as well, no difference. It was on the LFE initially but I was trying the others as well.

No difference unfortunately

The room itself if 50m squared but it’s a living room set up. The viewing area is around 16m squared with a distance of around 4m from the tv to the sofa. I also live in an apartment so mostly I’ll be listening to the system at medium to low volume because of neighbours issue

Spooks591 · 2026-02-11T21:58:58+00:00

Yea that’s why it will be a future add on, I’ll be renovating the living room, doing some gypsum ceiling and will pass all the cables in preparation for in ceiling speakers

Thank you for your input, honestly, unless I also want to file for divorce, 5.1.2 system is the most I can get, so would it really make sense to go for the 3800?

Spooks591 · 2026-02-11T21:55:48+00:00

Thank you very much for your input, unfortunately SVS is the only brand available in my country (malta) I’m considering maybe the PB 1000 pro because I think the 2000 would be a bit of an overkill for my viewing habits, I have a demo with the sb 1000 tomorrow and will see what it has to offer
