Re: Harman Kardon 595

Hi, probably two things that can go dead, 1) the woofer itself and/or 2) the amplifier. I will rule out poser supply cos the other speakers are working. Normally they have a separate amplifier than that of the woofer. If you are comfortable working with a soldering iron and a multi tester, after unplugging from the mains, then you open the enclosure and check the continuity of woofer which should read between 4-8 ohms, if it is open or no reading, replace just 2 wires/terminals involve with 3 or 4 screws. If the woofer reads a continuity, then it is the amp which normally is just a single power IC attached to an aluminum heatsink. In some instances, it may be a power transistor pair. In any case you have to be familiar with component level repair. Otherwise, you are probably better off asking a qualified service personnel to do the repair job. Hope this be of some help. Pls post how things turn up. Regards.

What cable connects a Dell PC to a Harmon Kardon HK395 sub woofer?

3.5 m/m. Normally it is color coded green. The pink connects the subwoofer to the speakers. Any color will work. Just mark both ends of wire jacks.

How to connect speakers to the sub-woofer and my iMac.

i believe that plug is special because it feeds not only audio signal but also voltage to power the speakers. so unless u know that the speakers will get power from the plug, it will probably not work

Sound sticks II

My problem is fixed now. I plugged the speakers into the earphone socket. There was no immediate effect just silence. I twiddled the control on the bass unit, played with the volume controls on the sticks. Then I realised the sound was back with the external speakers not the internal ones. It was as though the Harman Kardon system was re-booting itself. Very weird.
