Let say a driver's frequency range is 800 Hz to 20k Hz. (From the manufacturer)
Is it safe to crossover at 800hz or should it be crossover at 850 or 900hz?
Is it possible to damage the driver if crossover at 800 Hz without a steep slope? (Let say below 48db/oct)

Maybe there's more impact on our moods.
