Humming/buzzing


This is a nice speaker. You could get humming from the wires being crossed they actually do have polarity and better speakers will hum if the wires are crossed. The volume cloud also be too high without input. You also may have some interference with other audio wires or power wires close to the speaker.

Left speaker has developed a hum. Checked connections and all seems well. Sounds raspy like the speaker has blown.


This is likely due to a problem with the amplifier. You may have turned up the amp to the point of overdriving the speaker. The distortion at these high levels cause clipping and turn what was once crisp, clear sound into a muddied, garbled mess.

If the speaker is left connected to that source long enough, damage to the speaker and the amp may occur.

Without changing positions of the speakers: You can disconnect the affect Front or Rear L & R speakers and swap them (connect the L speaker to the R output of the amp and vice-versa). If the buzzing / hum "moves" to the other speaker, then the amplifier has the problem. If the buzzing / hum stays with the same speaker, the speaker has issues and is likely "blown".

Either way, it is probably not going to be a "cheap fix"

Good luck!

Iassume you mean you hear the buzz independently of the audio program - simply connecting the cable causes the buzz?

If tanything in the mix is powered from different AC sources you may have a different ground potential. Sometimes manipulating the orientation of one or more ac plugs will solve hum problems.

The "buzz" you hear is a power hum made by the power supply transformer. It's technically called "Lamination hum" caused by the revering of electrical current through the power supply transformer. In some cases the hum can vibrate the chassis causing other loose material to vibrate. If you can, go to your dealer and check to see if other units of this same type typically make a hum this loud, and if not, see if he can solve the problem for you.
