specific crossover settings for all possible combinations and situations. Therefore, if the crossover allows a range of filter adjustments, you should experiment for the best sound.

Here are some general recommendations: The crossover frequency can be set anywhere between 80 Hz and 175Hz, however a setting between 100 Hz to 150 Hz is recommended. Use a 12 dB or 18 dB per octave crossover slope. If you have a choice of filter types, the Butterworth type should work well. Adjust the acoustical balance between the full-range loudspeaker and the subwoofer by using the amplifier input level controls or the crossover output level controls.
