Addendum: Simulation Summary
These are simple simulations of a driver's impedance with given networks and a current-source amplifier. These may be useful to you as a general guide to recreate these results with an equalizer and voltage source, or better yet, if you want to get creative with networks and a current source. They are not carefully calibrated – they just resemble the real speaker's impedance. Along with the simulated impedance, you will see a simulation of these drive units driven by a current source in parallel with the equalization networks given on the previous table. This curve represents the voltage appearing across the driver terminals.
