A broken speaker..
Do your speakers sound muffled? Well read this guide!
This is a guide to help you how to replace the tweeters on your speakers. Blowing tweeters is not too hard to do if you really push your speakers and as they're not tough to replace, then you might as well replace them yourself rather than taking them into a repair shop.
I blew the tweeter in one of my speakers by getting a bit frisky with the volume control one night when I was having a get together at my house and had drank rather a lot. I thought I'd take some photos of the procedure as this isn't the first time I've had to do this and show you how to replace your own.
What's happened to the sound?!
How do you know when the tweeters have blown?
You'll know pretty much immediately when you're listening to a speaker if the tweeter has blown as the sound will go from sounding crisp, clean and clear, to sounding muffled and quiet. Put your ear next to the tweeter, if there is nothing coming out of it, then it needs replacing!
If you want to double check that it is the tweeter then you can fairly easily take the tweeter out of the other speaker and swap it over to see if that one makes sweet music. If you've blown both at the same time, all I can say is that must have been a good party..
When it comes to replacing the tweeter the best thing to do is to contact the manufacturers directly. I have bought from Monitor Audio several times and the customer service has been good. I can't speak for other manufacturers, but the manufacturer of the speaker is the first person to call. Once you've got it then it's time to get busy with the tools.
First thing to do is remove the bolts/screws
The speakers in this guide are Monitor Audio Silver 8, but the same thing applies to pretty much all speakers. You're going to need to unscrew the bolts or screws that are holding the tweeter in place. Find an appropriate allen key or screwdriver and get unscrewing. Remember to go anticlockwise (righty tighty, lefty loosey).

Bolts are out.. Now what?
After the bolts come out you're going to have to do a bit of fiddling just to get the tweeter out. This next step isn't going to apply to all speakers, but thankfully the Monitor Audio speakers in question have a bass port at the top. Lots of speakers do. If you look down the port you can see the back of the tweeter. All it takes is a bit of persuasion with a piece of wood and the tweeter will pop out.
If you have a different brand of speaker that has the port in a different area then you're going to have to try your best to aim for the tweeter. Worst case scenario if you have a brand of speaker than has the port behind the bass driver, take the bass driver (woofer) out and then put your arm inside the speaker box until you can reach the tweeter then pop it out.
As you can see in the following picture, if you look down the port you can see the back of the tweeter.

Give it a poke, but make sure you don't go too crazy with the pressure as they pop out a lot easier than they go back in!

Once the tweeter pops out then you'll see some push fit connectors on the back. Usually they are different sizes, so you don't have much of a struggle when it comes to disconnecting and reconnecting the cables.
Here are the connectors
Nylon head hammer
After you've reconnected the cables to the new tweeter, then you're going to have to get it back into the hole. This isn't particularly easy, they're made to be very tight and snug so take a bit of persuasion. This is where you need a decent tapping stick that wont damage anything. The best thing to use for that is a nylon hammer.
These are available at most builders merchants and are used for hitting plastic components, for example plastic topped pins that is used for installing pvc fascia. They don't mark plastic which is why they're used for this sort of purpose and they work great on things you don't want to damage, but do need a tap. Don't go hitting it with a normal hammer, you'll just mark or break it.
A nylon hammer is a great tapping tool
After a few (gentle) taps you should have..
A fixed speaker! OK you can't tell the difference from there, but just trust me it sounds better..
Is that it?
After this, you're done. Turn on your music and test out your handiwork! It's a cinch to replace your tweeters, the only painful part is paying for new ones.
Don't go so crazy with the volume control next time!

Thanks. Hopefully someone out there will be helped and get their speakers back to party mode again without too much hassle.
