Question about Altec Lansing VS4121 Speaker

Open Question

My subwoofer makes a loud popping sound.

I just recently moved, and my Altec Lansing VS4121 system worked fine. But now, when I turn it on, I hear a loud buzzing sound, then pop. It goes like this: buzz, pop, buzz, pop. It sounds like an electrical impulse, then a popping sound. If I put headphones into the jack on the speaker to control the sound, I can listen to music. But, without it in, all I get is that sound. Sounds like the system is getting intermittent power, but why would it work fine with headphones in? Please help me!

    I can hear the sound through the 2 satellites and the subwoofer/

    The speaker isnt blown, and all the connections seem good. Also, even if I dont have it plugged into the computer, and I just plug it into a wall, it still makes the sound.

    check for a blown speaker... the headphone jack bypasses the speakers when plugged in.

SOURCE: Altec Lansing VS4121 no sound

If removing and reinstalling the driver fixed your problem then there was nothing wrong with the speakes. There was probably a problem with your soundcard drivers.

That being said, you should double check that you speakers are plugged in to the right sound board connector and the power supply is plugged into the wall outlet.

Does you computer have a headphone jack? If it does, you might try plugging a headset into it to see if you can hear sound there. If you do then you'll know the soundboard is working properly and maybe the speakers really are part of the problem. CD/DVD drives usually have a headset jack, but this will only work if a cable was run inside the computer from the CD/DVD drive to either the soundboard or motherboard.

What kind of computer do you have? Do you know if you have on board sound or a seperate sound board?

It is unlikely that this is a problem with your speakers more likely that it is a problem with the DVD player itself. I would recomend trying another DVD player.

SOURCE: Umm I have an altec

Umm, so what's the question? The sub COULD be damaged or it could be reacting to being overdriven. Sometimes resonances form due to room- or nearby surface interactions. Try moving the sub a foot or two in each direction. Or turn the bass down.

Fix subwoofer


Pop open the back side of the sub and see if the to connections are soldered firmly to the wires/drivers themselves & make sure your system is grounded meaning the 3 pronged plug has to have the 3 post still connected to the power cord. If its broken off as most people do it'll cause that feedback or dull hummmmm noise.

I had a similar set and they drove me mad because they hissed when they were switched off. I bought a pair of Bowers and Wilkins MM1 instead. Fabulous.

If you want yours fixed you would have to take them to an electronics engineer or return them.

Subwoofer making load humming noise


The reason for the hum in the Altec Lansing VS4121 speaker system is the stray field of the power supply transformer. This stray field is strong enough to affect the amplifier. All other reasons given by numerous reports on the web do not apply. If you are handy and have got the time you may mitigate the problem by physically moving the amp away from the power supply or turning it 90 degrees. I managed to lift up the amp in my subwoofer by about 50 mm, which was difficult to achieve and did not cure the problem perfectly. I don't see any other way to solve this problem except you feed DC in from the outside and do not use the internal power supply. That would be really odd indeed

Altec Lansing VS4121, New Speakers, No Sound


If the speakers are brand new it makes me wonder how you know they worked fine in the States? I am also wondering how they were transported due to them probably being intolerant to extremes of temperature/humidity and probably vibration.

I am also wondering if you are using the correct supply voltage and type of supply.
If you are using the power adaptor supplied for use in the USA, it would probably be incompatible with your supply even though you are using a transformer.

If you are certain the speakers are in good order I suggest you obtain a power adaptor designed for your 220 volt 50Hz supply. I have browsed a little and cannot find a note of the power requirements for the integrated amplifier but this is presumably marked on the adaptor, the speaker or in the manual and so the power adaptor could be checked on and off load with a suitable voltmeter. I would be surprised to learn the supply is adequate
