Humming noise from sub - VS2621

Puchased a VS2621 a couple of weeks ago and the subwoofer emits a humming noise after the speakers have been turned on for a few minutes.  The humming doesn't come from the stereo speakers.

I am having the same problem.  The subwoofer emits a humming noise.  You can feel the vibration coming from the subwoofer.  Is this a defect?  I bought them on Black Friday.  They sound awesome, but I cant handle the humming noise.  Please help!

And that humming buzz in LOUD.  Made the mistake of leaving the subwoofer on at night and I could hear it in my bedroom.  Any response?

We have had a BXR1121 for a couple of years.  It suddenly started humming very loudly through the subwoofer at about 2am in the morning.  That is now all it does.  Anyone found a solution?

you have to turn the tone button down and the humming sound stops....they are really nice speakers...not a defect..

I tried messing with the tone knob. No help. Would be nice to see a response from Altec on this.

Got the VS2621 set for my office for Christmas...worked great for 2 weeks.  I came back to the office from a business trip and wondered what the buzzing sound was and found my speakers just sitting here buzzing.  Really annoying.  I did not notice it from the sub, just the satellites.  I plugged in the iPad and they still buzz...while the sound comes through the speakers.  I loved them when they worked...now they are paperweights.  Really disappointing!

I purchased these speakers about 3 weeks ago. They worked fine for about a week and then started to hum and buzz. The humming and buzzing got worse and worse and now they are essentially unusable. From what I can see searching the forums and internet this is not an isolated problem. What is Altec doing to rectify this problem? I always thought of Altec as a reputable compnay so I've got to believe they have a solution. Please respond.

Called Altec Lansing's number - 800-258-3288 - and told them what was happening.  They asked for a copy of the receipt to show when I purchased it and they created a return code for me.  Great, now I get to spend $15-$20 to ship back a defective product that I bought for $20 so they can hopefully ship me one that's better?  Not sure if this is really what I want to do.

I got a warranty RMA issued to me.  I paid about $10 to send back my speakers and got what appears to be new ones sent back.  So far the new ones don't hum like the last ones.  Yes it is a hassel to do all this for $20 speakers, but I figure if these replacement speakers work, they are worth a total of $30.

I am having the exact same problem and am really bummed.  I didn't even use them three times.  I sent in a request for a new subwoofer, but it sounds like they're all crap.  I hope to hear back soon.

I have the same model speakers. Just started buzzing in both sub-woofer and left speaker. Bought two months ago in February 2012. Looks like not worth the hassle or cost to replace. Maybe just forget about Altec Lansing future purchases and for all my clients. thanks for the information. Buyer be ware!

My RMA speakers continue to work fine.  It is possible they were using some bad transformers for awhile.  Remember the AC/DC transformer is in the subwoofer and electrical issues in transformers can create hum or buzzing sounds. At least Altec sent me some good speakers back, which is what a warranty is for.  The speakers they did send me appeared to be a standard retail box, so they may have fixed the issue.  But there still may be bad ones in out there.

I bought the same VS2621 speakers for my home PC. Great sound but the humming drives me nuts! It took a while before we finally figured it out. This was my first purchase with Altec Lansing. I think they were like $40-50, if no satisfaction I will probably toss them and buy new different ones. Very annoying that Hummmmm! Very annoying!

In my opinion the real heart of a corporation, no matter what type of business, is not that there are problems, but how the problems are resolved.

I just received a replacement set yesterday.  They look identical but so far, no hum.  They sound great.  The only hiccup in the RMA process was that I thought I only needed to return the sub (I even asked to confirm this) but apparently they needed the speakers too.  So I didn't have to ship them separately, they had me destroy my speakers and send a pic.  (Felt kind of weird to do that to perfectly fine speakers.)  Overall, I'm satisfied with Altec Lansing and am happy they replaced my defective unit.  I hope this set lasts.

hello,

I have the same problem with VS4621 after 12 months of use! But it was to replace the MX5021 which functioned 24 months! I like the Altec Lansing sound but there's a lot, I had trouble digesting the loss of MX5021 to 150 out of warranty but once again this time for € 75! This is the time too, I think Auter buy anything, it's not even worth trying to bother with an RMA for 75 but it is the total of the two I have left on your stomach. .

I recently purchased a speaker system for my computer at work, the VS2621 which does sound great. The problem is that after a while the subwolfer starts to hum loudly. This started immediately, I noticed it within a week or so. A couple times when I have been away from the office for an extended period and they are left on the hum is so loud it can be heard throughout the entire floor or our office and I have a private office.  I cannot use them now since if I forget and leave them on it sounds like an air-raid and it drives our employees out of the office! I just contacted Altec Lansing today on this via the website to see what can be done about it. I hadn't looked at this discussion before that to see that this is common. I assumed that I was an isolated case. If I had read this first I wouldn't have bought them.

I wish they would have given me the option of destroying them and sending a Pic. They had me return them and I had to cover the shipping costs. If I had bought them from A-L directly they may have offered me that, since they would be covering the shipping. Since I bought them from a retailer, I was told I was responsible for shipping. It wasn't a huge cost since I went UPS ground, but it still made me wonder if it was worth it. The next set may be just the same and then I would have another shipping charge. Hummm, maybe that is a good idea on A-L's part. eventually the consumer will quit spending money on shipping and the service order is closed.

20th February 2011, 08:44 PM    #15  pschitnis  diyAudio Member   Join Date: Jan 2011 Hello everyone I have solved the issue of output IC overheating and possibly shorting in the AVS 500. If you have replaced the power supply condenser and still not solved the problem of humming (more like motor boating) then read on. The output circuit uses 3 ICs TDA 2007A. Two of the ICs are used in normal stereo mode (6+6w) for the surround and satellite speakers. IC 10 is used in bridge configuration (12w) for driving the sub woofer. This circuit uses six electrolytic condensers of value (0.15mf) { C93, C94, C65, C66, C77, C78} for preventing the output going into high frequency oscillations. Unfortunately the engineers in Altec lansing seem to have not realized that these condensers being polarized will not perform as they are supposed to do and the whole circuit goes into unstable high frequency oscillations that bog down the power supply due to over current and hence the humming sound from the sub woofer. It reduces after sometime but the 3 ICs tend to get very hot as the high frequency oscillation (not audible to human ears) persists. Solution is very simple. Replace all six condensers with metal polyester types. (0.1mfd, 50V). Happy listening :-)

I have 2 sets of the VS4621 speaker systems, one at work and one at home. With one set I got the hum using one strip outlet but it went away when using a different strip outlet. The other set has buzzed ever since new about 3 months. today I was messing around with the connections. I pulled out the red multiprong jack and reinserted it and the buzz went away! we'll see if that lasts.

First you should be sure to check all the speaker
connections.  The sound could be caused by not having the speakers plugged
in all the way or a line near the audio cable.  It could also be the audio
cable, you may want to test to see if that is working as it should be. 
Another cause could be caused by electromagnetic interferences (nearby
cell/cordless phones, radio, etc.)  which can produce a hum in the
soundcards.  For this to happen the cell/cordless phone, etc. 
doesn't even have to be in the same room, just turned on, and it could be the
cause.  You may be able to fix this issue by trying a ferrite choke.  I always recommend testing it with another device to see if the issue still occurs, if the issue persists with the 2nd device then there is some kind of internal issue.
