There are many causes of buzz, so it should be checked step by step :
- Bad connection on the input connector, or cord.
- Amplifier, basically have the block diagram like this. View image.What would cause a buzz in speakers? - 25850665-l1qpqmriditabltrjczr2eku-2-0.jpg
If in one block damage, buzz can be heard.In the amplifier.
Generally occurs in the PSU and / or power amplifiers.
Fix it to the experts,because it requires a good knowledge of electronics.
Blown speaker cone, does not cause a buzz.
Short circuit along the wires supplying the audio, it will not cause any sound in the speakers, including the sound of music.
Try also, disconnect the input connector, whether the buzz is still audible. If after the input connector is removed, the buzz disappears, the possibility of buzz came from another device before the amplifier.

I think poor grounding somewhere, especially if there is a hum as well. Another possibility is a blown (detached) speaker cone.

Some buzzing in left speaker when low notes played

A couple of possibilities
One the speaker broke loose, typically there is lock tight on the threads that hold the speaker in place, lower frequencies can also cause buzzing noise,
I have fixed this problem in the past with a hot glue gun, running a small bead carefully around the edges of the speaker, bonding it to the unit,
Another possibility is the speaker is blown or worn out, over time speakers can weaken from constant use and coil movement, in this case the speaker should be replaced...

Hope this helps?

This is on a 15 watt Peavey Vypyr. I have a buzzing at the bottom end of my amp, when playing on the low E string. I plugged in my headphones and the buzzing went away while playing. I have also raised my...

The voice coil on the cube speakers must be scraping against the magnet.Or the speaker cone must be damaged causing it to flutter at low frequency where there will be large cone movement. Try removing the phono jack from your musical instrument/ guitar and touch the tip of the jack with your finger. You will hear a hum, now turn down the volume and listen to the speakers very closely and see if you can identify the flutter. All the same you will have to fix the speaker or replace it. Have you ever dropped the speakers, if so the speaker frame could have warped causing the scraping noise.

Every time I try to use 1/4 cables the eon 315s buzz bad... both of them do... I got a set of yorks that don't buzz on the same setup.... what is causing this? ??

If you use 1/4 inch cables they MUST be TRS cables (balanced lines). Guitar cables that do not have the third contact (ring) will have buzz and hum. Use either XLR or TRS cables. Also power the speakers and mixers from the SAME receptacle as the speakers.

I have noticed a buzzing sound generated from the amplifier when I play my low e string

Several possibilities come to mind:

The speaker is driven too far mechanically causing the voice coil to go into a non-linear region.

The cabinet, stuff inside, grille cloth, or even a logo on the cabinet is resonant and rattles.

Your guitar setup is not quite right leading to "fret buzz"

To troubleshoot, reduce volume and see if that helps...

No sound coming out of left speaker, just buzzing

The amp inside probably has failed on the one side. The buzzing might be the ripple of the power supply driving into the speaker. DO NOT use it till repaired or speaker MAY be damaged.

When turning my Marshal MG250 DFX on, there is a terrible buzzing sound. I have tried it on different speakers and the buzzing still occurs. It does not change in volume when i adjust the volume. Whats the...

This is likely a filter capacitor issue. The right tool to troubleshoot is an oscilloscope. This could also be a failed power amp that is driving high DC current with ripple into your speaker. This can permanently damage the speaker. Repair this before using it.

My Fishman Loudbox 100 bass speaker buzzes- what could it be? Someone suggests it could be a poor ground, and to replace the input wire, etc. Does he mean the guitar input cable? The speaker does not sound...

It is a poor ground but it is not necessarily in your amp.
If it is only buzzing when you have a guitar or other piece of equipment connected try a new lead cable.
If it buzzes all of the time......remove the cover at the rear of the amp and remove control panel.
Inspect the feed line to the input. If it is loose or broken....repair or take to have repaired.

After each note there is a buzz

There is a possibility that your speakers either one or both are becoming faulty. Try going out of the outputs into an amplifier and speakers that is known by you to have clean sound and see what happens. Also if there is a headphone out on your keyboards; is the buzz still there?
