Hi
Can anyone tell me how to dis-assemble the speakers. The problems I am looking to fix are that some grilles have been pushed in and there is a rattle inside the center speaker. It looks like one just levers the plastic front from the wooden box, can anyone confirm, as I'm not looking to break the plastic, it seems pretty fixed. The speaker model numbers are SS-CNP5000 and SS-MSP5000. There are no screws, and the hex bolt heads appear to be moulded in.

Sorry "the hex bolt heads appear to be moulded in." Would be better expanded, that is the hex heads appear to be moulded fakes, rather than real bolts awaiting undoing.

Most cheap speakers have the plastic front uglyfication part just push fitted into the particleboard box, with a ribbed rubber bung in a hole in the box that a plastic protrusion of the front part pushes into, In the times i have removed them, the rubber has partially pulled out some of the particle board because of the rachet shaped ribs on it.

Or its glued in, which from experience with crap speakers is very likely

Yeah it looks like it might be the ratchet job, must be some way to release the ratchets?

Yes, but not with retaining the ability to be re-assembled. Design for disassemblly is not the same as design for servicability.

I think when they are recovering speakers they just crush the cabinets and rely on the drivers popping out, To be honest its not something I have actually ever seen any specific disassembly process for.

I'll see if I can pull the ratchets out then. (I hate that)

Is it reasonable to think that fitness for purpose might include some basic serviceability?

No, the item has to be guaranteed, that means that the retailer will replace it.

There is no point in spending more on fasteners etc on something as low value as a generic speaker in a cheap box. Any replacements that they cant get out of replacing because of abuse of the item will just be replaced with another or the whole system refunded and get sent to one of their clearance centers and resold without speakers.

Hmmmm Its vintage is 2008, so its outside the standard years warranty...

What is Sony's provision after the warranty expires? Replace the whole thing? Will Sony still replace it? Some how I doubt it.

So how did the speaker grills get pushed in exactly?
When you say you hear a rattle, is it when you pick the speaker up and shake it? Or when you turn up the volume?

Kids no doubt pushed the grilles in, can't expect that fixed under warranty however it should still be reasonably fixable.

The rattle is on shaking - and is not a result of user action. Not currently wired up so not been tested, however a vibration may well also result. If I could get inside I imagine it would be simple to fix....

To answer the question above - I do doubt that Sony will replace speakers with pushed in grills. They would site the pushed in grills as 'abuse' and consequently void any warranty / severely limit any CGA chances.
BUT, at the same time, I think the Muteki's are non-serviceable, so you may be stuck.
If they sound bad due to the rattling, bugger.
But on the other hand, there will be other speakers around that will out perform the Muteki's - for not much money, so it could be a good excuse to upgrade :-)
