In Reply to: Von Schweikert Audio VR4-jr overall impedance posted by devilcoach on March 27, 2007 at 07:22:22:
The crossover network effectively disconnects each driver out of its operating band so your amplifier only sees a single driver in each portion of the frequency range. The standard, parallel resistance calculation you performed is invalid for this configuration.If they say it's a nominal 6 ohm system impedance then it probably is.
You can generate an impedance plot of the speaker yourself but you need to add a resistor in series and then measure across it at various points throughout the frequency range and plot the results.
