Thanks for this! Just made this repair yesterday. I had to do the same jumper cable deal- the rear (negative) xlr terminal had come off the board, so I patched it into the negative terminal of the TRS jack which has a way better connection.
Thanks for the tips at the end of the video. I have some M-Audio AV-40s that are buzzing and then at high volumes distorting. Common problem as I understand it... anyway I've been toying with the idea of taking them apart to see if it's a DIY fixable thing. I don't know anything about electronics so I appreciate the video.
Cheng capacitors are out of Taiwan, not China, and are not terrible. Nothing high-performance or high-reliability, but usually not much of an issue. What's really iffy though is that they would place that one capacitor leaning onto i'd say a big bridge rectifier! Those things tend to run a bit warm, there's no harm to the rectifier to run it at 130°C so it's common to size them like that for cost reasons, but the capacitor won't like that for very long, in fact it wouldn't like that even if it was a top quality unit straight out of Japan. And once one cap is gone, it'll tend to spike and kill multiple others. Just leaning the rectifier away might make a world of difference.
good that somebody knows how to fix these,i have Deluxe ones which heats in few hours of work and 1 of the speakers is abit louder than the other but other than that i never had problems with them thank god,way too many ppl complain about the inside work.
Also, I have a pair of BX8a Deluxes, and there is a noticeable mains hum in both my speakers, and apparently in a lot of these, and someone found that moving the motherboard away from the power supply removed the noise, so I'm going to try and get something in between those two to block the power supply from sending the noise to the motherboard.
I would make sure all the heat sinks are mated well to the amplifier circuits with the thermal compound between heat sink and chip. I really only understand a few basics about electronics.
Man i need som help. The subwoofer on my left speaker(Also M Audio BX8s) just stopped working. But i noticed that when i put some pressure with my hand on the subwoofer cone, it starts working again. What should i do?
Get a meter and see if it is blown. With the speaker disconnected hook up your multimeter and check the impedance, if it is blown the meter will read infinite impedance, if it's good it will read 0 or 1 I believe. Swap amplifier boards on your monitors and see if the problem moves to the known good subwoofer. I'm nothing close to an electrical engineer but I'm guessing your sub is blown. Hope this helps
I have the same problem, some times it work and then suddenly it stop working but if i put some pressure it start working, do you fix the problem @90sDawg ?
Great video. Thanks. I have M8 and the bass started to give in after 5 years, and one speaker started sparkling. Are they blown? Why would they just cave in like this? Can one fix blown speakers? What specifically has happened to blown speakers anyway? They've just been played at a moderate volume.
@@lorenmorgan1931 They don't "leak". That's glue to keep the large capacitors solder connections intact as they have to sustain a lot of vibration. If the capacitors are blown they may (or may not) become convex on top instead of flat. You can remove them and test with a multimeter. It's more likely to be a solder joint problem.
@@stinkworx Mine were for sure blown, and the old solder was a bitch to remove. I'm shocked there was that much on there. to be honest. Either way got it off the best I could (had an extremely high melting point too), cleaned it up, put all brand new caps on, and listening to them as we speak. :) Actually I was lucky, found a guy in another chat that had replaced them in his and showed me which ones he bought.
@@agrowmate3807 Thanks for sharing, will keep this in mind if any other issues appear. It seems that most of them are because of bulging caps. Funny the video that you shared, he had a much easier time desoldering that I did on mine. Not sure what type of solder was used at the factory but it was globbed on thick! I had to crank my iron up to an insane temp, and was starting to wonder if my iron was even hot enough to loosen the caps.
Somehow both of mine got burnt in one day after years of use! One and then the other. One actually began to smoke!! Hooked them up one at a time to an optical to RCA convertor coming from a new TV, they began to make a clicking sound and burned within seconds! Anyone can guess what happened?? After opening one up, the cap does look a very tiny bit bulged.
i know this is late but i have humming too and i thought it was the capacitors so i chamged them and it made the humming very silent but i dont get any playback. do you have any ideas of what it might be?
do you still have these? i'm so confused by it. i threw away the leads accidentally and i don't know how many amps the pwoer cables should have. i need to buy some news ones. i'm here in the uk. is it 13amp power cables or 15 amp?
I no longer have them but those monitors are the same as most powered monitors in the US. The power supply is internal and the lead/power cable is the same as any you would with a desktop pc that uses 120v AC. The power cables don't have any volt or amps. Hope this helps.
My BX8 has a working power supply LED but does not give any sound. I already checked the cable, input to board and board to speaker connection, no problem. Capacitors also look ok. Any advice? Should I visually identify bad solder joints?
Have you hooked a meter to your speakers to make sure they are good? If speaker is good and you don't see any bad solder joints then I would guess the amplifier circuit is bad. Just a guess. Swap speakers to boards. Try swapping any components you can to narrow the problem down to a single piece. Good luck b.
Super. I have a pair that I bought used, and they are BX5, rather than what this guy has, but I couldn't be more pleased. The sound has been crystal clear and not boosted in any range. I'm still pleased that after the right one started humming, I might be able to fix it myself. So I'm happy, even after daring to take it apart to see if I can salvage them.
Hey I have a little problem here with mines and it’s that the tweeter works perfectly fine but the woofer is giving me a humming sound maybe theres something loose in the cables but I can’t get in to the board because some Screws doesn’t want to come out what should i do?
If you've already done all the cheap troubleshooting (swapping cables) and you're sure the problem is on the board then you'll have to find a way to get the board out of the enclosure. If the screw is stripped you can possibly use a screw extractor bit. Make sure the power outlet is properly grounded. Get a ground fault indicator plug to test it. If you're using good xlr cables and you have a good ground then I would start looking at the board. Change your power cable also while you're at it. Good luck bro.
My speaker is buzzing and I'm attempting to remove the back panel so I can review the issue. However, I'm not having much luck getting it off. Is there a trick to this? There are 4 screws in the bottom left that are in a square formation that will not come out. They just spin. Any guidance would be appreciated.
trying to get my BX8a's apart but the bastards glued the harness connectors together >_< Did yours have the same problem...? gonna try to scrape it off and disconnect them. Problem I'm having with one of mine is that the woofer stopped firing after a while but if I push in on the cone slightly it starts to work again :\ I'm guessing maybe a loose connection at the terminal or maybe a weak solder joint? I know this is an old post but would really appreciate some feedback from you as you obviously know what your doing.
I honestly had no clue what I was doing, just opened it up and started poking around. The wire harness in my monitor was zip tied together, making it difficult to remove the crossover and amp. I carefully cut the zip tie with wire snips. Your woofer problem should be easy to fix just like my problem was. Likely a bad solder joint/connection or broken circuit path. Glad the video helped. Good luck.
Sean, trying to sell mine and I️ just ran into the same problem - the sub doesn’t work on one of them, actually will pop in and then pop back out randomly but mostly out/off... did you ever find and fix the problem with yours sir?
If I’m seeing a brownish-yellowish semi-hard substance that appears to have leaked out onto the circuit board at the bottom of each capacitor, what does this indicate? Capacitors shot? Will the substance on the board surface affect the board (cause it to short, or other issues)? If so, how do I️ clean off the surface of the board to remove the substance, with messing up the board? Any help or advice or suggestions that anyone could provide greatly appreciated...
Question. I live in the U.S corporation and My BX8s are set to the standard 115 V but I find that they get really hot. If I change the AC Select to 230, will this help the monitors stay cool and will it mess anything up?
I know this is an old video... But one of my BX8 has started to like blow up the sound real loud of the low end frequencies, when it is turned up too loud. Not that it is the loudest it has ever been, not even close, but it just started having this sensitivity... What could be the issue? Happened shortly after getting the BX Subwoofer. Both are M-Audio. Goes over soundcard Scarlett 2i2.
I hate using my scarlett 2i2 with these monitors. You have to use unbalanced cables so you get a lot of noise. If the bass freqs. are sounding distorted I would look at the capacitors on the m audio board. I'm assuming you're not cranking these monitors and using them as PA speakers.
The monitors themselves are about half way up in volume. I find it easier to control from the Scarlett 2i2 there on after. But what would the capacitors do? I mean, I guess the M-Audio set should work just fine together, right? Also the noise is reduced dramatically, if I pause the Subwoofer. So it's like they share the noise output. Pausing the subwoofer doesn't remove the noise though.
Hey Adam, I've recently bought BX8 D2's and I got an issue with them. Both of them have "brum" in woofers and "buzz" in tweeters. Any idea what might be the problem. I checked the connection and other stuff that might cause this, but no difference. Thx
+Riaan de Beer I RMA'd them, the technician told me that it is a manufacturing problem, that the transformers are too close to the amplifier circuits and on top of that, the transformers had some loose metal plates (they are not toroid). After changign the transformers, it is slightly better.
+Russ Gilliom No, there should even be a spare fuse in the fuse box in the speaker. At-least.. Both of my BX8A's came with spare fuses. Just pull the fuse out from the back of the speaker and you should see a spare 1 in a rubber casing of sorts.
one of my bx8a monitors just stopped playing,also the blue power indicator light is off ..i switched the fuses and nothing has changed .how can this problem be solved .
Test the circuit find where it's dead there's an issue there more than likely but those trouble shooting things he spoke of should be chk first. obvious signs of bad solider wires touching swollen caps.. there's a Chn Uncle Doug he makes Amps & fixs old amps…he has some solid basic electronics vids where he's trouble shooting old tube amps but you can pick up a lot of things from him. He's a cool ol dude too.
I'm thinking about buying a set of these in a day or two. is it a good idea? are they well built? I've heard great reviews about their sound but don't want them to crap out right away. any thoughts?
I have sold the ones in this video because I was moving. I bought another pair just because I like the way these sound and honestly, I can't afford yamaha's. I also use a pair of beyerdynamic dt770's for mixing. Ultimately it just comes down knowing how your speakers sound. I've heard of people producing good mixes on cheap computer speakers. Good luck.
I have a pair & I've been checking em out against the JBL 3series 8" & M Audio is very close & has more Bass & about 70% more volume. I don't see the need to keep the JBL so I debating whether to keep the M Audios they are in Mint Cond. or keep the demo'd JBL's??? I might let mine go if yer interested I'd throw in some Monster XLR to 1/4" Bal. cables like New they still smell new lol.
Watchman4u hey thanks. I ended up getting a set locally used (pretty much brand new tho) for $200. they sound great but one thing I do notice is that the bass can be phased out depending on where I sit. like if I'm in front of my computer there's not much bass. but at the back of my small bedroom studio it's booming. any thoughts?
Adam... How are you doing? I have the original Maudis bx8a speakers and all of a sudden the base plays but the smaller speakers do not... I'm not exactly a tech guy in I would be willing to try if you somehow you give me an assist to fix them if oossi le or at least help me figure it out
I'm doing good brother. Open up the enclosure. Hook an ohm meter (cheap multi meter from walmart should do)to the tweeter in question. If there is infinite resistance then the tweeter is probably blown. Take the wires going to the tweeter and connect them to the bass speakers and see if there is any output. This should tell you if it's a problem with the amp or the tweeter. Hope this helps.
Adam Young the bass works. It's both tweeters that don't function.. I only now saw your reply.. I greatly appreciate you responding. I will still follow your instructions and put the meter on it. Will get back to you Thanks immensely
Mandell Taylor sounds like a grounding issue. Sit the monitor on the floor, use a different speaker cable (make sure it's not a mic cable), and plug the power into a powerstrip. If it doesn't stop, you have a grounding issue.
You gotta keep in mind the model used in this video is over 10 years old, newest models may be different. I have a slightly newer set of Bx8a's and amp removal is the same. Just remove all the perimeter screws on the metal plate on the back of the cabinet. Hope this helps
@@HeavyInHawaii hello it was not neccessary. I found out that i can change the fuse directly at the power cord entrance.. it even had a spare fuse! So cool!
have the same problem with a BX8a after a power surge, i changed the fuse with the replacement that comes with it but still the Blue light doesnt turn on and no sound comes out of the speaker, what should i check?
When bassora kick drum hits? If so it's the caps for sure. I came here in hopes of seeing what caps I need before opening mine. One of mine went bad then weeks later the other one went equally as bad. It started distorting at certain volumes then within weeks they go to hell at all volume, and is because the caps no longer hold the extra power necessary to deliver the power the speakers need.
Glad this video is still helpful to anyone 6 years later

I've read about these problems for other monitors too, not just the BX! pretty good insight.
Great video. I've been having volume drop issues in one, now buzzing in that same one, so I'll take it apart and give this a shot.
Hi. Cool vid, thanks. The tweeter is not working in one of mine. Would I need to drain the caps to open it up and check the connections?
I would always drain the caps anytime you open any device to work on it. I’m not a trained service tech so better safe than sorry.

Thanks man.
I turned the amplifiers on while the power cord was disconnected. From what I understand this drains the power from the capacitors.
How did you go about doing this?
What part?
Turning on the amplifiers on while the power cord was disconnected.
Make sure monitors are not plugged in to the wall. Turn the power switch on. Do this before messing with the electrical components inside.
Ok, thank you
hi where are u based i want come with my monitor
lol, I'm in Hawaii brother. You'd be much better served finding a local shop that works on electronics. Thanks for checking out the video.
I know this video is old but when you unplugged your XLR cable, did it still hum? Mines does so I'm debating if it's the XLR cable or one of the caps.

have the same problem with a BX8a after a power surge, i changed the fuse with the replacement that comes with it but still the Blue light doesnt turn on and no sound comes out of the speaker, what should i check?
@@FrankMoreiraV Did you ever fix your blue light not turning on? If so what did you do?
@@gete-wasted8438 never found a proper solution for it, it just won't turn on.
fuck yes Pantera as a test track. I got no power . no blue light. seems to be common issue. sent a service request for help. lost
I have these I have bad crackling noise no matter what I do anyone chime in on this thanks
When bassora kick drum hits? If so it's the caps for sure. I came here in hopes of seeing what caps I need before opening mine. One of mine went bad then weeks later the other one went equally as bad. It started distorting at certain volumes then within weeks they go to hell at all volume, and is because the caps no longer hold the extra power necessary to deliver the power the speakers need.
@@lorenmorgan1931 yea any bass hit I have to cut it all the way down for the crackle stops so did u fix urs yet with the caps?
@@ken79bu Was actually coming here to find what caps I need to order. I am going to open mine up here in a little bit to see and order from DigiKey.
@@lorenmorgan1931 well I found the caps off eBay 10 for 8bucks I hope that fix the crackling and distortion problems
@@ken79bu I assumed fixed yours? Mine started having a blown speaker pop, then degraded to making literal fart noises with any bass.
Both of my BX8's are cracking and now basically unusable. - Never again will I buy M Audio garbage
Did you buy them new? Did you check the capacitors? They may have popped.Sorry you had bad luck with your monitors. Guess I've been lucky so far.
My tweeter has a dent in it, can I push the back of it to push out the dent if I take the face off or is the back of the cone not accessible in these?
+David “Waitwutmyname” Hager No idea how to fix a tweeter. I've seen someone pull out the dent with a needle and then super gluing the pin hole shut.
+Adam Young thanks, its not that bad so I think I'm just gonna leave it.
use a vacuum cleaner nozzle carefully, or if you aren't scared, put your mouth over it and suck it out..😀
Double sided tape worked for me! Gently push in to stick and then pull out to undo the dent.
