How/where do I set the Low-Pass Filter (Crossover)?
Created: Jul 16 2018 | Updated: Aug 24 2018
The Low-Pass Filter (also called Crossover) controls the subwoofer’s upper-frequency cut-off. Depending on model, the subwoofer's volume (level) control may be on the subwoofer's main control panel (either on the front, back, or bottom) or controlled using a free smart phone App (Dynamo 600X/800X/1100X/1600X) available for iOS and Android devices.
The Low Pass Filter lets you to adjust the low-pass frequency for the left and right (RCA or speaker level) inputs. This setting is not applied to the LFE (RCA or XLR) inputs, instead leaving the task of bass management to your audio/video processor.
As a general rule, the Low-Pass Filter should be set at a value approximately equal to (or below) 70% of your main speaker’s lowest frequency response. For example, your speaker’s frequency response goes down to 43Hz. 70% of 43Hz equals 30.1, so you should set the subwoofer’s low pass filter to 30Hz. We advise that once you try the recommended setting using the formula above, you should try the surrounding settings as well. If you are uncertain of your main speaker low-frequency response, start with a setting of 35Hz. You will not harm anything by experimenting with different settings.
Remember, because this setting only applies to Left/Right inputs. This setting is not used if your subwoofer is only connected via a LFE input. If you are using a subwoofer without a dedicated LFE input (i.e. it has a Right/LFE input), you will need to set the Low Pass Filter to Bypass. or to its highest settting.
