Don't think the difference of 18/22vdc would make the noise. Is the noise constant? maybe too close to another device like a microphone or a something that would give off radio waves. Cell phones and cordless telephones. wireless gateways/routers. Try moving speakers away from these types of devices.

Sounds like a problem in the speakers' internal power supply, maybe a faulty capacitor. Speakers need to be looked at by a technician, or replaced with a new set.

I have altec lansing speakers AVS500 and have no sound


It sounds like the subwoofer speaker has blown. If you are comfortable working with a soldering iron and speakers then you can open the case and replace the speaker with a replacement subwoofer speaker. A good online store for replacement speakers is PartsExpress.com

Harmon Speaker distortion


Hi, I came across a similar problem with an old Altec and the the solution was to only replace the defective side. Actually, what was replaced was only the speaker itself inside the enclosure which was cheaper rather than replacing the entire assembly. An electronics technician (not necessarily a computer tech) can do the job since some soldering might be involved.
