How to Use the Presets
Setting the low-pass filter frequency on the subwoofer to match the top cabinet’s high-pass filter frequency and balancing their levels will achieve the smoothest sound across the frequency range.
There are no incompatible combinations.
Selecting high numbered presets on subs with low-numbered presets on tops will result in increased system output in the overlap range, which can be helpful in some situations but can also result in a “boomy” sound.
When the subwoofer levels are to be run higher than tops levels, (which is almost always) the effective crossover moves higher in frequency. If you intend to run your system “bass-heavy” it’s recommended to run lower-numbered presets on the subs and higher-numbered presets on the tops to avoid an excessively “boomy” sound.
Selecting low-numbered presets on subs with high-numbered presets on tops may result in a lack of “punch” in certain combinations. This is most likely when not enough level is available from the subwoofer(s).
When not enough output is available from the sub(s), using a preset combination with overlap can help provide a little more bass level but it does limit the maximum level of the tops due to the added demand for low-frequencies from the tops.
It’s recommended that you try several, if not all, combinations when first setting up to determine which combination works best in each environment. You will likely choose different combinations for wood floors, concrete floors and outdoors.
Experiment with different combinations to dial in your preferred combination in different environments.
