I am assuming that you already know which wires go to which speaker and all you need to know is which one is negative and which one is positive. Here is one way to find out. If you can access the speakers at all or at least see the cones, it will be easy.
Take a small 1.5v battery and connect it to the wires in question, connect one end to the positive(+) and the other to the negative (-) side of the battery, don't do it for a long time, just enough to observe movement on the speaker cones. Observe the cones of the speakers, if the cones get pushed or moves out, take note of the polarity of the battery because now you know which is which. Now if the cones, move inward or it gets sucked in when you apply voltage, then it's backwards.

Hiw many mA does the adapter for labtec lcs150 speakers need


6V DC 200 MA; plus shell, minus center pin
aka, Panasonic AC Adapter Model No. RP-65A or equiv..

You want to make sure the plug at the speaker end is wired properly: + on the outer barrel and minus on the center pin (the adapter will have a little graphic for verification purposes). If so, your 500ma adapter should work fine. The voltage might be a little high but nothing the speakers cannot handle I would think.

I need to know the voltage of the speaker for ac adapter matching


The speakers may have a label that has the voltage printed on it.
You can check the Bose WEB site for the specs of your model speakers. You need to know the polarity of the connector, if you get it wrong you could destroy your speakers.
You may need to contact Bose support if the specs do not help you.

What is rating of Spin 50 Power Module. Lost mine


Should it be a power supply that outputs AC and converts to DC inside the speaker case, or is it a wall adapter the outputs DC straight to the built in amplifier?
Some speakers have the voltage and polarity for the plug on the back of the speaker where the power lead plugs in. As they are only small speakers of probably a couple of watts it may only need about 2 Amps or less. Higher current is fine as the amp will only use what it needs to work correctly but I would'nt go below 2 Amps.

I just need to know the specs on an AC adapter for my old Labteck SS-100 speakers. I want to buy a generic AC Adapter at Radio Shack and they suggested that I contact Tech Support.


i do not see a reason of wastig money on that venture as these speakers were not that hot when first made, humming noise from them was most annoying "feature"... but...

labtec ad-4 adapter was used in them, and output was 6vdc, 400ma, plug was 5.5mm x 2.1 mm with negative centre, if i recall, there was compartment in them for 4 "d" size batteries as well.

if you find this advice helpful, please do not hesitate to leave your recommendation and vote for me, thanx!

What is the polarity of the jbl platinum series speakers


Speakers don't really have Polarity ... they have Phase. The audiophile wants the speaker cone acting in the same direction not opposite directions. So, watch your wire - one conductor will have a rib on it, the other smooth. You pick which you want to hook to the red or the + or what the mark is on your devices pick the other conductor for the other side, black or - or what ever matches.

Make sense???
