I find it hard to believe Holman would recommend 50Hz since THX (which he's the first two letters of) specify 80Hz on all systems (assuming the sub and sats both work to that frequency cleanly and evenly).
I tend to use 80Hz since I find that I localize effects much above that, but I've also got my room treated with bass trapping and correctly positioned speakers. If you've got more bass issues between 80-120 Hz from where your sats are positioned (since they're positioned for best imaging which is rarely the best location for bass like your sub is placed for), then setting the crossover frequency higher can be a better way to go since it's better to know what the bass is doing than have that little bit of extra imaging down low.
Quick example, if your front speakers are placed 3 ft away from the front wall, that wall is going to cause a cancellation right at 94Hz. So setting your sub above that would be a good idea (or have a thick bass trap behind it would be a better solution, but I digress)
