    4691 et. seq. network evolution

    Esoteric, perhaps, but a little research uncovered this interesting evolution of network topology for JBL's workhorse Sound Reinforcement two-way:

    4691B Anybody have a READABLE version? L-Pad attenuation.

    SR4725 Attempts to balance drivers, an attenuation switch, lower Xover frequency for 2226H?

    SR4725A Fixed attenuation, add Neutrix.

    SR4725X Back home again, no attenuation, 1/4" inputs GONE.
