computer speaker question??

  1. I have an old set of altec lansing computer speakers, and i was wondering if it was possible to turn them into home theater speakers since all surround speakers hook into the sub and then the sub has a 3 wire hookup.

    not really a electrinics guru so might be a stupid question?

    Hello and welcome to techspot :)

    What is your AL configuration? Is it 2.1, or 5.1?
    I dun really understand what you're asking as you did not tell much about your speaker. If possible please write your AL series here...

    P.S. If you want to mod the 2.1 speakers to be 5.1, it's not possible logically, but you can have a surround* sound if you have another plug-ins for media player.

    You also need to match up or exceed the wattage output of the amplifier with the speakers.
    You must also ensure that the speakers are the correct ohmage or damage could be done to both speakers and amplifier.

    I wouldnt use them as your mains, maybe just use them as your surrounds. I would guess depending on the model. They probably arent rated very high on wattage. Depending on your receiver/amp you can adjust the volume on the rears. The receiver probably has a test signal where you can try to even out the output. Is it a prologic or dolby digital receiver? Also if the receiver supports it, I think it sounds better if you run all the speakers from the receiver instead of running them through the sub.

    What do you mean match up or exceed the wattage output? Its just as easy to burn up a pair of speakers with an underpowered amp as it is with an over powered amp. Most amps run 8 ohm, more expensive runs can run 2 and 4 ohm speakers. But arent most PC speakers 8 ohms anyways?

    lol....You forgot to include your blood type there! :D

    I think you can use them as your surround without any issues. You have RCA cables long enough?

    I am not sure how to hook them up since the sub has a cord with three 3.5 jacks in the back and each satellite has RCA jacks

    What is the model number of your sub? And who is it made by?

    I don't see the problem of these speakers not being able to be used for home theater use. If you're using the whole set of speakers that it came with, then just plug the "Audio in" like you would from your PC but instead sourced from your HT system's Audio/Line out (like the DVD player or AV controller etc), either by digital means (optical/Coaxial) or the old fashion Analogue RCA/3.5mm or 6.5mm plug.
