The Theater Series always had a Zobel. Only the Professional Series didn't at one time. I would suggest using the current crossover, making R1 and R2 each 16Ω. All other parts are the same. I'll send an E-Mail with the cabinet plans for the old Theater four π speaker along with the crossover schematic and layout from the current four π model.
