Hook a graphic equalizer between the piano and speakers, and turn down all sliders above 8 kHz. Since the highest note of a piano is 4186 Hz (4.186 kHz), you'll still hear all the notes but cut the hiss. If the hiss is coming from the speaker's power amplifier (in which case the equalizer won't help), turn down the speaker volume and turn up the piano volume. Live instruments generally need some doctoring to sound good through high-quality stereo equipment, as they only produce a limited range of frequencies whereas good speakers reproduce a lot more - including hiss.

This would be burnt out voice coils. This takes some special tools and material to rebuild them. etech.com or ebay or amazon may have the things you need to rebuild it. It would likely come with instructions as well but there are how stuff works videos and maybe youtube vids as well to watch to see how it's done.

Hi, cases like that always comes u. Earlier you said just replaced it, that's not too good for anew monitor speaker.

You could test the fuse inside the speaker if it's still working, might be power fluctuation that might have caused it to blow.but you need to test it. If it is the fuse,fine! you can replace it, it does not cost much to replace.

Also if i can recall,most new stuffs always comes with guarantee with it,right?. I would suggest you could take it back and get a replacement, and i guess if they see it,since it is on guarantee,they can fix it for you without even charging you a penny.

Hope that helped.

Thanks and feel free to pass on your comment.

Thanks for using fixya..

Sometimes there is a very annoying buzzing noise coming from the speakers. Why is that? Can it have something to do with the earth? I have grounded the speakers to an iron stick outside the house.


LOL. This is a common, easily solveable problem. Remove your cellphone or anything that emits radiation of any sort from the general area. Don't believe me? send a text message while sitting net to your speakers. It does this even if you arent sending a message because your phone sends intermittent signals to the cell tower. the radiation being emitted from the phone does weird things with the magnets inside the speakers.

One of my speakers has a constant hum and an intermittent crackle/hiss while music playing. Please help!


Swap speakers from the output of the receiver or amplifier. If you hear it from the same speaker, then the speaker is bad.

Check the capacitor, if its swollen or rusty it needs replacing, also check the fuse.

M-Audio BX5a Speaker Problem


Not sure i can help with the led problem but i just fixed a hissing problem with one of my BX5a monitors. It developed a hiss when on (both tweeter and bass) and a very loud thump when switched off. I found a slightly swollen power filter capacitor on the internal board. They are the two biggest black capacitors, labelled as 25v 6800uf. Only one of these was bulging. The tops of these should be totally flat. The indented X on top of the caps make any bulge easy to spot. Worth opening it up and having a quick look. I could only find 35v 6800uf caps at my local electronics store but they did the job ($3 each). I swapped both out and it's now working great. An easy DIY fix, just be sure to always have the power cord unplugged before you put your hands anywhere near the guts of the thing. Hope it helps.
