Overview Impedance Plots wanted for Infinity to avoid destroyed Amps (e.g. RS/Kappa)

There are several models on the marked with passive high pass crossover network for the bass transducer. Consequence is an enhancement of the bass transmission (only a small area around 40-50Hz so as acoustical low pass character of 24db/octave instead 12db/octave)
Additional the impedance goes in this area down below 1 ohms at several models. This means danger for destroy amplifier stages.
Therefore I want to have a line up of all associate impedance plots and crossover network circuits to older Infinity multi way speakers.
On the web there are only any few plots - go to the attachments.

Many thanks for the progress of the completion.

in post #43+44 under
Infinity 8 Kappa Rescue Project
there is to find an approach from me as general solution for models with minimum impedance below 3 ohms.

Except the Kappa (Reference Standard) series there are several other series, e.g. IRS-Sigma/Epsilon - go to

An overall view of all models is here:
