    • This image shows the complete setup with which you will end up. With a little bit of work you can soon enjoy the clear sound of true harman kardon speakers.

    • Please note: This guide will destroy the original cable/connector which is used to connect the Apple Pro Speakers to an iMac, Power Mac or the Griffin iFire.

    • Please also note that – as with every electronical repair or modification guide – you alone are responsible for your own health and the health of others. Also be aware that you alone are responsible for any damaged electronic equipment.

    • Cut each of the speaker cables. To get the maximum length you can cut the cables near the white "knob" which merges the two cables.

    • Remove the outer insulation on each speaker cable. Remove up to two inch of isolation. You can use a scissor or a wire stripper. Be ultra careful not to damage or cut the inner wires.

    • Two wires are inside each speaker cable.

    • Now also remove the insulation of the small inner wires. Again be careful not to cut the cables as they are very small.

    • You should end up with something like this.

    • Now you will need to find out the proper polarity of the speakers, i.e. which cable is negative (-) and which is positive (+).

    • Unfortunately – at the time where I did this conversion – I did not photograph the cable colors. But there is an easy trick to find out the polarity:

    • In this image you see two banana plugs and a AA battery. Just imagine these are two stripped wires from one of the speaker cables.

    : 手順 7、 1の画像 1

    • Now connect one wire to the negative terminal (-) and the other to the positive terminal (+) of the AA battery.

    • If the speaker cone bulges out (left image), you've got the proper polarity. You now know that the wire on the positive terminal of the AA battery is your "+" wire, i.e. it will connect with the "+" output of your amp.

    • If the speaker cone moves in (right image), the polarity is reversed. You now know that the wire on the negative terminal of the AA battery would be your "+" wire, i.e. it will connect with the "+" output of your amp.

    • Now solder an extension cable to each of the stripped wires. If you want you can use a red wire for positive (+) and a black wire for negative (-) so you can easily connect the speakers with the amp later.

    • Finally insulate the wires properly. Use shrinking tube and/or electrical tape.

    • If you like you can also use shrinking tube on the previously insulated wires, so you end up with a single cable (per speaker) again.

  11. この手順は未翻訳です。 翻訳を手伝う。

    : 手順 10、 1の画像 1

    • Now strip the extension cables of each speaker. You are now ready to connect the speakers to your amp.

    • If you like you can use banana plugs with the stripped cables (like seen in the image).

    翻訳

    : 手順 11、 1の画像 1

    • You are almost done. Now properly connect the speaker cables/banana plugs with your amp. Connect your Mac or PC or some other audio device with the amp and enjoy your old new Apple Pro Speakers.

    • Please note that the Apple Pro Speakers don't sound too loud, but that's by design. Still, their sound is very clean and detailed (on a class-d amp).

Amp shown appears to be a Muse Audio M20 EX2 TA2020

Good guide. I'm doing the same thing with a pair of these speakers, but I think I'll use new cables soldered to the speaker terminals.

One quibble though. I believe the correct term for the wire covering is "insulation", not isolation, and in step 9, you "insulate" the wires, rather than isolate.

Thanks chuck, I have corrected the wire covering term :)

Will this amplifier work for my Apple Pro speakers?

Should work. Not the 'best' amp out there, but same tripath chip as most other class-d amps on the market.
