How do I select proper crossover points and slopes?

5.7 How do I select proper crossover points and slopes? [DK]
Basically, this requires a degree of patience. The subwoofer should be started off at about 100Hz and adjusted until you are happy with the sound. Keep in mind that the higher the crossover point, the more power the driver on the high-pass will be able to handle but raising excessively may cause the low-pass driver to sound raspy or unnatural. The idea here is to first make rough selections to protect the drivers and then to fine tune crossover point selections to achieve optimum fidelity. It's all a matter of what sounds good to you after that, but remember that even minute changes in crossover frequency can make dramatic differences in the way your system sounds and images.

As a rule, subs should be crossed over no higher than 120Hz, a 6 1/2 mid should be able to handle about 90 Hz, a 5 1/4" should be okay with about 100Hz, a 4" -- about 500Hz, and tweeters vary from about 3500-5000Hz. These points all assume the use of a 12dB/octave crossover ... if you have a steeper roll-off a lower crossover point may be chosen. Remember, these are not hard and fast rules but rather a rule of thumb to help you get started (and so you don't blow up all your speakers when you are setting your gains!).
