Question about Altec Lansing 621 Computer Speakers

1 Answer

AVS500 powered subwoofer

I have this ancient computer sound system which has been perfectly adequate for my computer usage, until the last few weeks. The subwoofer has developed this extremely annoying sound which I think may be interference of some kind. You cannot hear it on the small speakers. It is purely the subwoofer. The system has been in the same spot for over two years, so I cannot understand what has started to affect it. It is a constant quick mid range pulsating kind of sound. It last for several minutes and goes for a while to re-appear a little later without warning. I use the 5 speaker surround setting. How can I troubleshoot the system and sort the problem out. The troubleshoot on the computer has not helped at all.

Creative Inspire 5200 system won't work

Hi. Check your speaker system with a different audio device like iPod or any MP3 Player using the same jacks. If the speaker system gives out sounds then nothing is wrong with it... if no sounds come out, then you know what I mean...

Try to replace the speaker of your sub-woofer... maybe that can fix it!

I had the same problem and found the root cause to be the RF speaker connector at the back of the subwoofer. The male and female connectors are OK. It is the 5 male pins inside the connector and the way they connect to the female holes that is the problem. Wiggle the RF speker connector as you move it in and out until you get 100% of audio voilume back. Once you get it back, do not move the connector. Have not found a permanent solution to date beyond this.

My subwoofer (Altec Lansing[AVS500]) is always makeing a thumping

You could only verify this by gaining access to the rear of the speaker but I suspect that the 'spider' has come unglued. This is a device that surrounds the lower (inner) end of the cone to provide a second point of suspension; without this, the voice coil can slap against the side or bottom of the magnet structure.
I don't think a repair is an economical choice for these; repairs only make sense for 'professional' speakers that cost several hundred dollars to replace.

Speakers Popping loudly occasionally. Died for several days. Now working again but still making sounds.

The problem is a burned transistor inside the subwoofer. It depends of country's transistor manufacturer. It is supposed to be of a low quality. It's not important for the scope. Mine is knocked down for a year. I saved the electronic schematic diagram and the transistor specs, but lost. I confirmed the cause opening the subwoofer and examine the board. The indicated transistor surrounded area is burned indeed. If anyone find the article in web, please, post here.

Unwanted sound from subwoofer.

switch your subwoofer off from the socket for at least 30 minutes and check if the noise is still there,if its still there open it and play a movie then press it lower if the sound stops then you will have to put some toilet papers at the back of it ,thats what I did to mine.
