If you use a single 0.7mH coil, you will be flat to 1.6kHz. That's what the crossover in the Professional Series cabinets uses. This is a pseudo first-order configuration, which doesn't provide the sort of curve you'd expect: It removes about 2dB from 1kHz up - and attenuation is fairly constant above that point. So if you choose to crossover lower, you'll need a different crossover, and you'll probably want to use a Zobel. The single coil pseudo first-order solution does not require a Zobel.
