Speaker blown? How do I open it up to see? And how do I fix it?

Sounds like something might be blown, there is a very intense vibration and rumbling/crackling noise when bass is on. How do I take the covering from off of the subwoofer (without cutting it off) to see the speaker? Or is it some other problem im unaware of?

Try without having the input plugged on the speaker ... to determine if the noise is coming from cable or receiver

Very low volume on all inputs

first thing,,,,make sure the speaker wires are not touching each other.
i dont think it would be a fuse because that would cut the sound could open the unit to check for a fuse or fuses.
if none of the above help,then take the unit to a tech.i suspect a blown channel which means a capacitor needs to be more thing...swap speakers over to make sure your speaker isnt blown

I have a pair of new Alesis Elevate 3 active monitors and the right one emits a faint high pitch whine. It's coming from inside the speaker, probably from the amplifier circuit. Any ideas what may cause...

Have you tried some hot glue to dampen the caps body? Plus this will reduce the internal vibrations from the speaker cones which can eventually vibrate components loose.

Sounds as if the woofer is blown. seems t be a vibrating noise. this will be the third time fixing this problem.

get some higher rated speakers as this will happen time after time, or you could turn the bass down lol

When i put my ear to the front of the sub, it makes a sound more like a rattling / grumbling than a clear bass sound. Is this normal sub function or is there something wrong?

It sounds like you subwoofer may have a blown speaker.
If it is new, take it back and replace it.

If it's not under a warranty, take the case off and examine the speaker. If you see a tear in the fabric part of the speaker cone, or along the edge... it is a "blown" speaker.

These can be fixed, but you will more than likely have to take it somewhere to get it done. If there is a company near you that does professional car installations, they will more than likely be able to fix it... or should at least know someone who can.

When i turn the sub up it sounds like it's clipping or it is hitting something but if i hold the plastic ports on the back it seems to stop?

Your ports are vibrating. You need to seal them and this should fix this problem. I would use some dynomat around the outside edges of the port to prevent air leakage and to stop the vibration. You may use a bit of silicone on the outside edge of the port too for further protection from vibration and leaks. Good luck.

One of my speakers has started emitting a " fartinf like sound, it's not blown but sounds like someting vibrating against the woofer, if that makes sense?

Check to make sure all screws are tight. If they are, it's possible the surround or the spider on a woofer is letting go. Check to see that they are intact.

Woofer not working

sounds like the voice coil could be open or damaged. the woofer can be reconed. reconing replaces all the moving parts in the speaker frame returning to new condition in most cases.

Mission speakers...i think i've blown one of them...

I'm guessing you mean one of the bass drivers (as standmount or floorstanding speakers don't have subs as such). Place your hand lightly against the driver when playing some music at normal volume, there should be some vibration (this increases the louder you play). If there's no vibration, you're probably right.

Contact Mission, who can send you a new driver, contact a Mission dealer to see how much it'll cost to go through the dealer network. I'd recommend going down the latter route if you are unsure of what to do yourself.

Just noticed you posted this in March, in which case, I hope you got it fixed (or are enjoying your new pair instead!).
