The Delta 10 is the preferred driver. The Alpha 10 can also be used, but the Delta is better for this application.
No crossover changes are needed to use the TD12S in this model; It's the same whichever driver is used. This is largely because no Zobel is required. The relatively low crossover point is in the range where impedance is pretty flat in most woofers.
