Re: Binks Audio Test CD to check driver "health"

Charlie,
Are these plots from measured electrical data at the crossover connections to the speakers or is this an electrical simulation using nominal speaker impedances?

Samuel is correct. Not the best way but if you decide to do this Keep the level low. the nominal crossovers frequencies are:
Woofer 30-400Hz
Midrange 400-1kHz
Mid dome 1kHz- 6kHz
Tweeter 6kHz- 12kHz
Super tweeter 12kHz 30kHz ( not likely to hear any of these )
The tones within each these ranges will be heard from the corresponding driver. A toilet paper tube or something similar held to your ear and near or over the specific driver will help funnel the sound to your ear.?
There is considerable overlap between drivers in the crossover. For example you will hear frequencies outside the 400-1kHz range coming from the midrange. Distortion may be hard to isolate because all the drivers will be operational during this test.
driver.
Below is an example of what you will hear from each driver. Of course the vertical axis is loudness. In general you will hear the range between where the driver is 10dB down for the middle of its range.
Blue-woofer
Brown-midrange
Green-middome
Purple-Tweeter
The ?supertweeter is not shown
You may notice the midrange and the middle have significant overlap in the range 750-2700hz
