I have a pair of Logitech LS11 computer speakers but cannot find the power cord adapter for them. The speakers require an input of "10V-500mA and 50-60 Hz". In my box of "spare parts" I found a Netgear power cord with an adapter that fits the speakers with Input of "100-120v--47-63Hz--0.6A" and Output of "12v.....1A". Will this power cord work in the speakers I have? These speakers are so old that Logitech no longer has spare parts for them.
If I end up having to try and find a power cord adapter online how closely must the output match speaker requirements to work right?
If the speakers are so old... why not just buy another pair. You can get them pretty cheap and they will probably sound better than the old ones. You can get some for under 15.00 on Amazon.

It might work or you may burn them up.
None of the specs you list really matter except voltage and amperage and of course the connector has to fit.
So the speakers call for 10 volts and 500ma (1/2 amp)
The adapter you found provides 12volts and 1A (1 amp), 2 volts more than you need and twice the required amps.
Try it, the worst that can happen is that you burn them up, or find another adapter online.

Amperage doesn’t matter in this case...just means it can supply more than what will be required. Volts are close, less than 20% off. If they are analog speakers I doubt they would burn up.
It just might. It's twice the rated amount. They have a small amplifier which is rated to run at a certain number of amps. They make power adapters to match the equipment. Like you said, 2 extra volts will probably not matter, the amps?, probably not either, it's still a low number.
@OP if it doesn't work, just get a universal adapter, $14 at Amazon.
“Current is a bit different. A constant-voltage supply doesn’t determine the current: the load, which in this case is the device, does. If Johnny wants to eat two apples, he’s only going to eat two whether you put 2, 3, 5, or 20 apples on the table. A device that wants 2 A of current works the same way. It will draw 2 A whether the power supply can only provide the 2 A, or whether it could have supplied 3, 5, or 20 A. The current rating of a supply is what it can deliver, not what it will always force thru the load somehow. In that sense, unlike with voltage, the current rating of a power supply must be at least what the device wants but there is no harm in it being higher. A 9 volt 5 amp supply is a superset of a 9 volt 2 amp supply, for example.”
Many thanks to those of you gave me input and advice. Much appreciated. I did try the power adapter I had and it seems to be working fine.
The sound is good enough for the podcasts I want to listen to but I will definitely get some new speakers.
