How to open the case of the speakers?

I am trying to open the right speaker since the volume button is loose or broke. I took the metalic mesh off and unscrewed the 4 screws that hold the speaker but I can't pull it out and I don't want to force it. Is there another way to get to the inside of the speaker without damaging the case?

    This speaker has no stickers that may be concealing screws and I have checked under the rubber feet if there are screws there but there's none. It seems that the case is one solid plastic box that doesn't come apart. Only other possibility is the back but I'm unable to open it without damaging the case and it may be all one piece.

    loose volume switch which i have broken by turning too far



  • Enel Sillon Oct 28, 2008

    yes, I did what most of you said: I created a small hole on the back between the dark and light gray tones, put a flat screwdriver and forced the two pieces to open. It was glued. Once I fixed/soldered back the cables inside, I glued the case again with less glue in case I need to perform another "operation"... thanks!!

I dropped my speaker and the volume button got pushed into the speaker. I cut along the grey and black pieces and used a flat-head screw driver to break to 2 pieces apart. I fixed the button and super-glued the 2 pieces back together. Good as new.

This may help?
in between the bottom of the right speaker casing, theres two tones ( black and grey ). [personally i didnt care about the speakers seeing as how i got them for free.] i cut in between the two tones with a hand saw to make an opening. then used a flat head screwdriver to wedge it open which was pretty easy after an opening was created.

be wary of the volume knob cause in opening it, theres soldered wires underneath. good luck

Since u hav removed the mesh and the 4 screws that hold the case of the speaker .As you said that the speaker has no opening points , most companies manufacture the speaker by sandwiching two parts together. In order to open the case of the speaker , you will have to see for a joint line on the edges . it indicates the attachment between the two parts of the speaker . If you find an opening at the back of the speaker as you have mentioned , try to remove the two joints of the speaker by pulling gently at the opposite ends .

Hello...my left speaker doesnt work


Hi,
It might be a wiring issue or your computer. What speakers do you use in general? Because I have the same problem now and it seems like the wiring is loose inside, so I can only get it to work by twisting and turning the wire for now.

So yeah
Try doing this:
Open up your left speaker and see if the wiring is disconnected. If it is, connect it using a soldering iron. It might be in the wire line that goes into the speaker. If not then the speakers or the circuitry inside is dead. Replace it.

If you do not want to replace it then try:
Go into your computer (in Windows), right-click the volume icon and click Playback Devices. Click on speakers (it should have a check mark on it), then click Properties. A box will open up. Click on Levels and click Balance, then check if the slider with an L is low or all the way to the left. If it is low then turn it up. If it is not then right click on the volume icon again, and this time click Open Volume Mixer. Hover your mouse over Speakers (or in some cases headphones) and you should see the brand (in my case it says VIA HD Audio). Go to the website and look for the latest audio driver for your PC/Laptop. Install it, and if it fixes the problem, GRET. If not, then replace the speakers, the left speaker is dead.

Or maybe it is not connected......check the connections.

Question about Peavey Escort 3000 300 watt portable PA, both right and left mains work fine, but the right speaker has distortion sound. Even if I change speakers the right out speaker circuit is dist


sounds like an internal connection problem. open access panel and check the solder connection is not broken or loose. Be sure the metal mesh jacket is not touching the lead wire as that would cause a scratchy noise and feedback, or maybe near the internal cable causing feedback

We have older speakers that came with our computer, and we just moved and since we've moved no sound has come out of the speakers. i have checked a million times and everything's plugged in. i...


First check if the driver for your speakers is up to date. For all we know maibe something that was installed automaticaly or by some one might be interfearing with them. Go to the Window menu, click on Conrol Panel, click on speaker settings, and check to see if anything looks off (like everything is gray and you can't really select anything). If everything seems ok check all the volume settings. Remember there are 3 things that control the volume on the speakers. 1: the nob on the speakers; 2: the volume on your desktop (lower right side next to the clock); 3: the volume on the program you are using (like windows media player). Another thing to remember is some computers come with a mute button (ether on the keyboard or monitor. If your computer has a play/skip/stop buttons it most likely has a mute button. Oh, and some computers have a volume nob next to the CD/DVD player (where you put in disks). Maibe some one turned it down as they grabed to move it. Make sure it's also turned up. If they're all turned up then most likely something got bumped loose during the move. In wich case you'll have to open it up and check the conections. It'd be a good idea to test some one elses speakers so you'll know if it's the computer or the speakers...or you could try pluging in the speakers you have into something else (like an MP3 Player).

One speaker no sound


I just want to confirm that the solution on another page from francis 8 works perfectly ( http://www.fixya.com/support/t3709832-speakers_stopped_working_cannot ). We have two sets of Creatures in our offices, one had been shelved (by someone less persevering than me) due to this problem years ago and my set started this trouble a few days ago. Troubleshot everything, every cable, setting, combination, spare speakers etc - nothing worked. Opening the offending speaker and pulling back the metal weight behind the speaker cone was the solution for BOTH of our units.
Big smiles all around :-)
Note - When you've opened the plastic shell and loosened the speaker from its mounting, the the big round metal piece/magnet sits within the actual speaker 'cage', slightly behind the speaker cone. It's tight but movable and can be pulled all the way back as far as it can go inside it's housing, away from the speaker cone.
Not sure why it gets pulled forward, but it isn't fixed in position and so could clearly get bumped by dropping the speaker or a reasonable impact of some sort. Once bumped forward it would severely limit cone movement and therefore volume.

Turned on the Privia PX-575R and sound distorted, seems as if bender is in use intermittantly when noone is touching it- and almost like speakers are blown, but volume was never set very high.


You should probably check the bender controller and the master volume potentiometer, they might be dirty / oxydized, in such case, you need to either disassemble and clean them or replace them.

Also check for bad solder contacts on wires, connector pins and any of the components (e.g. voltage regulators, capacitors and/or other components).

Check all connectors for any dirt / oxydation on the pins and clean them if necessary.

Also check the main power switch (dirty contacts may result in erratic behaviour of the unit), and, if we're talking onboard speakers, see if the speaker protection mesh is somewhat loose, it may vibrate and cause the speakers to have dirty / distorted sound (you need to fix the mesh firmly in place to stop it from vibrating).

It could alse be a problem elsewhere in the unit (a bad resistor or capacitor, possibly some other component), these are just some of the things that may cause the unit to have dirty sound.

Hope you can make it sound well again.

regards

Altec Lansing 745 ( 4 speakes 1 subwoofer)


I had the same problem w ith mine

Before giving up on them I decided i had nothing to lose by pulling them apart

Remove the base and screw hidden behind, reove the mesh cover and 4 screws hidden behind

Prise off the volume knob then unscrew the circuit board the vol control is fixed to

Now try the speaker whilst in bits

Mine miraculously worked at full volume straight away

I reasembled them and now they are fine

Just lucky maybe, who knows...but definately worth atry before you bin them

Multimedia speakers not playing up to potential


After I posted my problem, I browsed a bit further through the other posts and solutions, until I came across the excellent solution of TrickyTrev34 and gave it a try. However, I did not slice the cable, but did it as follows: <p> 1. Switch off power of the sound system on the subwoofer box. Disconnect the Front Right (FR) speaker box (the one with the volume control) from the subwoofer box.<br>
2. Remove the silver coloured metal oval on which the speaker box stands. Now you'll see a small screw at the bottom of the speaker box. remove it.<br> 3. Carefully remove the silver coloured metal protection plate (with all the little holes) from the front of the FR speaker box by wedging it from the top with a flathead screwdriver or other thin blunt object. Now you'll see the speaker and 4 holes with screws inside. Remove screws and speaker box opens up..<br> 4. Inside you should see six wires (Red, Blue, Yellow, White, Green & Black). Carefully cut the GREEN wire only. Insulate the both ends of the GREEN wire with electrical tape or heatshrink or similar.<br>
5. Put the FR speaker box back together in reversed order.<br> 6. Connect FR speaker back to the subwoofer box. Make sure the volume setting on your PC is very low, because when you switch back on the power of the subwoofer, you should be blasting again.<br>
<p> As TrickyTrev34 already mentioned, the only downside of this procedure is that it will disable the volume control on the FR speaker, but who cares, your sound system works again, and you can still control the volume via the PC playback control panel and/or the multi-media keyboard if you have one.<p>Thanks for giving the lead trickytrev34.

Right Speaker Hit the Floor


Im sorry to say so, but the fact that speaker can still monitor volume has nothing to do with its disability to produce sound. Im not a speaker wiz, but I can think of two possible reasons for what happened: 1. something has broken inside the speaker. in this case you will have to get it fixed\replaced. 2. some disconnection accured from the hit, a wire got teared or loosed. in this case, you might get lucky. open the speaker, and search for any torn wires. if you are handy you may be able to weld, replace, etc.
