According to Wayne's crossover table C5 and R3 ahould be 60 uF and 8 Ohms respectively...

Now even if I factor in 25% variation for the Zobel circuit allowance I don't even come cross the values Wayne has for C5. So why the discrepancy?

Omega Pro 15:
Re= 5.28 ohms
Le= 1.04 mH

R3 = 1.25 * 5.28 = 6.6 + 25% = 8.25 Ohms > OK
C3 = Le/Re squared = 1.04 x exp-3/5.28 squared = 37.3 uF +25% = 46.6 uF which is short of 60 uF
