Picture of Fixing Corsair SP2200 Crackling
The corsair SP2200 are great speakers, but they have some sort of factory defect in which the left speakers start to exhibit a crackle after some time. I decided to open mine and check what was causing it.

Please vote for me in the Fix & Improvement contest.

This fix is not confirmed yet to work on all cases, however, it does work for me.

As far as I know, I may be the only person to have attempted this fix and it may or may not be specific to my case/speaker.

Corsair has a great RMA service, and I recommend to talk to them. I only did this myself because I live in Panama and paying any kind of international shipping is cost-prohibitive.

I am not responsible for anything you do to your speakers.

Edit: Corsair seems to have discontinued this product, which makes this instructable even more important for those with crackly speakers than it was before.

Step 1: Dissassembly

First of all, the problem causing the crackle in the speaker is not in the left speaker, but on the circuits hosted on the right circuit. This can be observed by the fact that the crackling is present on the headphone output.

First, remove the speaker dust cover on the right speaker. You will find underneath speaker cover four Phillip screws. Remove all four of them.

On the base of the right speaker, you will find two rubber strips. Underneath the one facing the front of the speaker, you will need to remove three more Phillip screws. After removing those three screws, pry open the speakers starting from the upper side. It will require a moderate force to pry it open, but as long as you did not miss any of the seven screws it will open without being damaged.

The knobs can also be removed at this point. They are held by a friction fit, just pull them straight out.

Hi! I followed your guide to step 4 but now there is no music at all in the left speaker, just crackles and a constant hiss. I've checked the solderings with multimeter and they are ok. What can have happened?

What's the formula to calculate gain? It seems counter-intuitive to me that a lower resistance results in a quieter sound, but that's probably just because I don't know the formula

ATTENTION, the origin of the issue is probably completely different !!! Many elements lead to the conclusion that the potentiometer itself is the cause of the noise:

- The potentiometer is the only component located before every other components on the circuit, which is why the noise remains in the headphone output, and with the auxiliary input
- the noise appears at mid-volume, the area where it is used most of the time, it makes sense if it wears out on this zone

A multimeter cannot detect the noise because it is a high frequency signal, you could only detect it with a oscilloscope. And the potentiometer brand, DELTA, strongly looks like a cheap chinese manufacturer.

The solution proposed here consists in reducing the influence of the potentiometer flaw, not in fixing it. I am going to try and change the potentiometer, I will post to confirm it (or not) when i'm done.
how did that work out??
Unfortunately, changing it didn't affect the noise, hello frustration. Btw, I had to install a separated switch because I didn't find any stereo potentiometer with switch included Interestingly, that had a positive effect because I can now leave the potentiometer in the same position all the time (I change volume through the computer settings). The noise took 2 weeks to disappear and I don't have any crackling anymore even when I change the volume. I will try and get the crackling back to be able to locate the source. The causes of that noise are getting weirder and weirder, I cannot rationally recommend you to install a separated switch :)
these things really have a life on its own. the static buzz has magically stopped today. I wonder if any components get warm or hot after a while. maybe it's something there. having two sets with two diff behaviours is quite strange.
I have use this fix 6 months ago. However the crackeling has come back on one of my speakers (I have two sets)
I have noticed that when the power is on for prolonged times like hours on end) it will get more violent. Usually I unplug it, and the first few hours its fine.

My other set just started making a constant static buzzz in the left speaker (no more crackle though) and when the buzz appears the general volume seems to drop a bit.

Thanks so much, Michael! Wiring it to the headphone did the trick. Saved me from having to put my favorite speakers out on the curb. The 24 month warranty expired last month, of course.

Yes, it took a lot of force to open the speaker. The bottom part of the speaker front is held in place with plastic "pop-in" pieces, viewable in the step 2 picture. Pulling really hard was the only way to open the speaker. I didn't damage it though.

Thanks again.

moderate force? I'm putting a lot of force into it, and the bottom part of the faceplate just refuses to come off.
