HI:
Usually with audio humming, the cause is due to a bad capacitor on the amplifer portion of the unit. Bad filter capactor in the AC power suppy will cause whats known as AC ripple to enter the system causing motorboating sound or humming. Have the unit check by a technician for poor regulated DC voltage.

First Check for the cable or your players grounding/shielf wire.

i would replace it with another 4ohm speaker prefable with a 250 to 300 watt max and with 75 to 150 watt rms rating

try to unplug and then plug again all the speaker's connections...make sure you do the right connections...or get a AA or AAA size battery,put the + side of battery to the + of speaker(alone/unplug),and momentarily touch the negative(-) side of battery to the negative(-) of your speaker,,you must hear a click from your speaker...if there's no click,you have a defective speaker..

make sure that you had plugged your pin in green color plug or marked with head phone sign


i am sure that you had plugged speaker's pin in mic plug in most computers and laptop plugs of mic and speaker are in pair anyone could make mistake, if headphone marking worn out by regular rush of hand.

Most probably output capacitor need replacement.

Hi Jerry What Model....? Using a mobile phone camera would have helped in this situation. Before taking things apart I'll be very surprised if someone has the same speaker system in bits somewhere An electronics guy would trace the wire back to it's source to decide what it's being used for.

The "pluc pluc pluc" noise you're hearing from your Altec Lansing MX6021 Expressionist ULTRA 2.1 speakers could be a sign of a few different issues. Here are a few things you can try:

1. Check the cables: Make sure all cables are connected properly and there are no loose connections. Try using a different cable to see if that solves the problem.
2. Check the power supply: Ensure that the power supply is plugged in and working properly. Try using a different power outlet or power supply to see if that solves the problem.
3. Check the volume: Make sure that the volume on your device is turned up and the speakers are not on mute.
4. Try a different device: Connect the speakers to a different device to see if the issue is with your laptop or the speakers.
5. Check for software updates: Visit the Altec Lansing website to see if there are any software updates or firmware updates available for your speakers.

If none of these solutions work, it may be time to consider contacting Altec Lansing customer support or a professional audio technician for further assistance.
