What does Impedance 4-8 ohms mean? Is it either/or, or from 4 to 8 or what??
Good question. I've never seen a tweeter rated like this before. Here's what I do know, though. The impedance rating of a loudspeaker, whether a woofer, mid, tweeter, etc... is a nominal value that represents a kind of average impedance over the speaker's stated operational range. The "average" is usually skewed a little toward the low end but represents the load that an amplifier will see if directly connected to the driver without any passive crossover in the circuit. Speaker (driver) impedance changes with frequency. So, for example, an 8 ohm speaker may measure exactly 8 ohms at only a very few frequencies. Look at some woofer impedance curves to see what I mean. As far as a driver being rated at 4-8 ohms, maybe someone at PE can run one of these on a Dayton system (above 2KHz) and find out what the real impedance is. Or if it measures more than 4 ohms on an ohmeter, say 5+, it may be an 8 ohm driver.
