Check to see where you are plugging it in. Plug all equipment into the outlet strips powered by the same AC outlet. Or use a direct box. Check your cords also. And lastly, return the product if you are under warranty and get yourself a new one. If the problem is still occuring, it probably has to be on your part, not the product. So try one of those examples before you return it.

Sounds like you have a bad connection somewhere. Make sure all of your connections are secure. If theres anything that is a little loose you'll get that hum. You might also try replacing your cable too. If it became pinched somewhere it could cause that problem

I have the Klipsch Sub-10 Subwoofer, and it no longer plays music. Now it hums (vibrates constant) and corresponds (louder or softer) with volume control. Light is home but no one home situation. V


Does the subwoofer have the same hum when the input cables have been unplugged? Many input cables use very fine conductors, which often fail. A bad cable will often introduce a hum and prevent a signal from getting through. If the noise is still present without the input cable(s) connected, then repair options are limited. No schematics are available. There's a daughterboard that has been available, but its failure usually causes the system to die (short-circuit). The cost to repair the amplifier may be close to the cost to replace the entire sub.

Humming/buzzing


This is a nice speaker. You could get humming from the wires being crossed they actually do have polarity and better speakers will hum if the wires are crossed. The volume cloud also be too high without input. You also may have some interference with other audio wires or power wires close to the speaker.

Woofer is humming


Usually a faulty cable or blown speaker will cause a humming. If it is a constant humming I would surmise a faulty cable. On the other hand, if the humming comes and goes I would guess a faulty speaker.

No sound


Hello endow1, hi, try this test, unplug you Logitech audio in plug and touch the input, you should hear a humming sound, Adjust the volume settings to high to hear it. If you cannot hear the humming sound, then there are problems you need to check. Place you speakers near your ear and adjust the volume Up and Down, you may hear a soft hum that should go up and down. Absence of the hum means that the speaker has loose connection from amplifier to speaker driver, or loss of power, check to see if there is pilot light.

jd40,
Sounds like a grounding issue. The first two places to look into is the powered subwoofer and antenna. During your last test, did you leave the FM antenna and subwoofer connected? Many times the hum is directly related to the antenna and/or the subwoofer and to how they are grounded; creating a ground loop through the receivers ground on the outlet. If the antenna is grounded to the dwellings wiring, hum is inevitable and sometime you can get a ground loop hum from how or how & where the subwoofer is grounded. Try taking them completely out of the loop.

Also try taking it further back to the basics, start with the receiver plugged into a known good grounded outlet with no surge or line conditioner in the loop and nothing connected to the receiver, nothing. Use one speaker and different wire to test each speaker output while in tuner and any other mode but phono. With no signal, you will either get nothing (no hum or static) or just static in the tuner mode. No hum is a good sign. Some systems will mute the speakers if no signal is connected to eliminate the static from being produced through the speakers but a ground loop hum will most likely still be produced even in mute. If you get a hum when nothing is connected to the receiver, try looking into getting a better grounded outlet, even maybe to a different dwelling.

Constant hum from speakers


It sounds like you might have a grounding issue. Try connecting to the wall outlet with a ground prong lifting adapter. Not just the speakers but the source plugged into the speakers also. Good luck.

Humminf sound from subwoofer


Most humming sounds in speakers is due to electrical currents or wifi signals nearby the speakers.

Do you have any electrical cables near the speakers? Do you have any wifi device near the speakers?

If so move them out/away and see if there is any difference.
