I have recently had about one-hundred small speakers donated to me. The speakers have 64 ohms stamped onto their backs and I assume that this is their impedance. Nearly every schematic that I have ever seen referenced using either a 4 or 8 ohm speaker.
I have to admit that I only have a general working knowledge of impedance and most discussions about impedance only mentioned matching between either high-Z or low-Z. The differences mentioned were what I would consider somewhat extreme, perhaps 8 ohm for low impedance, versus 1k ohm for high impedance or thereabouts.
What I am asking is whether or not I would be able to use these 64 ohm speakers with virtually any amplifier circuit with a low output impedance or is 64 ohms high enough that I will need to do some sort of high impedance matching? What general design changes should I be considering when trying to use a 64 ohm speaker in a circuit that originally called for an 8 ohm?
Thanks in advance...
Edit: As another non-related question, I have noticed that whenever anyone uses the word "ohm" in a post, it turns into an invalid hyperlink. Is there a particular reason for this?"
