Apple M6531 Harman Kardon G4 PowerMac and iMac Pro Speakers

These Apple Pro Speakers feature powerful Harman Kardon audio technology. They connect to your Power Mac G4 desktop systems using a single cable which provides 20 watts of sound (10 watts/channel) to the speakers with a frequency range of 70 hertz to 20 kilohertz.

Apple Pro Speakers are different from the speakers that came with the Power Mac G4 Cube: While the Apple Pro Speakers look very similar to the Power Mac G4 Cube speakers, the Apple Pro Speakers get their power from the computer and require a system with an Apple speaker minijack like the one on the G4 Power Mac tower and G4 iMac. The Power Mac G4 Cube speakers, on the other hand, are USB-powered and are designed to work only with Power Mac G4 Cube systems. Also, the G4 Cube speakers have an external amplifier, whereas the Power Mac G4 has an internal amplifier that supports the Apple Pro Speakers.

The analog-based speakers require systems with an Apple speaker minijack. They are not USB-based speaker. Be advised that the cording is beige not white. They are priced at $50 with shipping at cost. To inquire contact Dave via kootenaymac.tel

Apple iMac G4 17' 800MHz desktop computer

For sale: a vintage G4 17" iMac LCD flat screen all-in-one computer. It has an 800MHz processor that has been over-clocked to run OS X 10.5 Leopard. It has an 80GB hard drive, 768MB ram and an optical drive for burning CD's and reading DVD's. It has 3 smudged spots on the screen so it is priced at $80 CDN. Add an Apple keyboard and mouse for $30. Add $40 for a set of Harmon Kardon speakers as shown. This is a previous generation iMac and will not run newer software or OS and will not play YouTube videos smoothly but is very good for those who need to run legacy software programs and basic internet, email and word processing or to bring the screen close for viewing. Local pickup in Nelson BC Canada preferred. To inquire contact Dave via kootenaymac.tel
