How quickly it transitions is pretty steep, so you might be able to get away with adding as little as 10Hz to your speaker's lowest reproduceable frequency. Start with 20, then tweak to preference to get the best transition.

有一个好准则就是看看你的喇叭频率响应曲线，看看他最低工作频率是多少、或者是再哪一个频率点输出音压掉到－3db ，找出这个点然后再加上20HZ 把这数值当作重低音分频点。

That said, the crossover's slope (i.e. how quickly it transitions) is pretty steep, so you might be able to get away with adding as little as 10Hz to your speaker's lowest reproduceable frequency. Start with 20, then tweak to preference to get the best transition.
