Using Apple Pro Speakers with a class-d amplifier

Wat je nodig hebt

  1. Using Apple Pro Speakers with a class-d amplifier, Using Apple Pro Speakers with a class-d amplifier: stap 1, afbeelding 1 van 1
    • 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.

  2. Using Apple Pro Speakers with a class-d amplifier: stap 2, afbeelding 1 van 1
    • 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.

  3. Using Apple Pro Speakers with a class-d amplifier: stap 3, afbeelding 1 van 1
    • 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.

  4. Using Apple Pro Speakers with a class-d amplifier: stap 4, afbeelding 1 van 1
    • Now also remove the insulation of the small inner wires. Again be careful not to cut the cables as they are very small.

  5. Using Apple Pro Speakers with a class-d amplifier: stap 5, afbeelding 1 van 1
    • You should end up with something like this.

  6. Using Apple Pro Speakers with a class-d amplifier: stap 6, afbeelding 1 van 1
    • 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.

  7. Using Apple Pro Speakers with a class-d amplifier: stap 7, afbeelding 1 van 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.

  8. Using Apple Pro Speakers with a class-d amplifier: stap 8, afbeelding 1 van 1
    • 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.

  9. Using Apple Pro Speakers with a class-d amplifier: stap 9, afbeelding 1 van 1
    • 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.

  10. Using Apple Pro Speakers with a class-d amplifier: stap 10, afbeelding 1 van 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).

  11. Using Apple Pro Speakers with a class-d amplifier: stap 11, afbeelding 1 van 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).

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.
