About my speakersimulator; it uses gyrator circuits optimized to emulate the freq. response of a 12" speaker in a standard combo.

I used the 12" open back speaker in the Revalver DirectinX plugin as the basis of my backwardsingeneering. I haven't build it yet, but Pspice simulations shows a BIG similarity. My design is only 0.5dB wrong in the area 0 to 2kHz. The same goes from 3kHz to the peak at 7kHz. I only need to design a notch round 2kHz and to optimize the componentvalues better/closer to standard values.
