    Speaker to Receiver Compatibility
    Last week you guys helped me to connect an old Aiwa stereo system to my Sony TV/Apple TV. It was just in the closet taking up room and it is now such an improvement in sound.

    So there is one other thing in the closet that I would really like to use too. It is a set of Marantz HD 770 speakers. Big old tall things but they have both woofers/tweeters built in and sounded really great back when we used them. These Marantz speakers have an impetence of 8 ohms and the (original) speakers that I have now connected to the Aiwa (NSX999) are 6 ohms. Will the Marantz speakers work, will it overheat the Aiwa? I would hate to mess up what I have going now but hoping for a little better sound plus use my vintage speakers.

    They shouldn't overheat the Aiwa. An impedance of 8 Ohms will just give you a bit lower sound than that of 6 Ohms. Most stereo systems are able to drive speakers of from 4 to 16 Ohms without doing any damage. Just don't go lower than 4 Ohms.

    Thank you for the quick response. And by lower sound, is that a good thing, like more bass sound from having built in woofers? I'm not looking for professional sound out of this old equipment, just the best sound out of what I have laying around.

    Those Marantz should blow away the sound of the Aiwas. Would guess they're also more efficient than the Aiwa speakers which would provide more sound at lower volume settings. They should improve at least your action movie watching experience a good bit.
    I cannot be held responsible for the things that come out of my mouth.
    In the Windows world, most everything folks don't understand is called a virus.
