Apple Pro Speakers M6531 feature the powerful Harman Kardon audio technology.

These speakers are compatible with: Power Mac G4 (Digital Audio) Power Mac G4 (QuickSilver) Power Mac G4 (QuickSilver 2002) Power Mac G4 (Mirrored Drive Doors) Power Mac G4 (FW 800) iMac (Flat Panel) iMac (17-inch Flat Panel) iMac (1GHz Flat Panel) iMac (USB 2.0)

Key features: Mini Jack The analog-based speakers require systems with an Apple speaker mini jack (2.5mm plug instead of the 3.5mm industry standard). Currently, Apple Pro Speakers should only be used with the new G4-based iMac or the Power Mac G4 with mini jack.

The Apple Pro Speakers can be used with the Harman/Kardon iSub Subwoofer system for an even richer audio experience.

They connect to your Power Mac G4 (Digital Audio) using a single cable which provides 20 watts of sound to the speakers with a frequency range of 70 hertz to 20 kilohertz.
