Setup and Configuration of Subwoofers

How do I connect my subwoofer?

Created: Jul 16 2018 | Updated: Aug 24 2018

Subwoofers (depending on model) come with different connection methods, including Speaker Level and Line Level RCA and XLR, as well as wireless options.

In the case of wireless connections, you will have to refer to your subwoofer or wireless transmitter’s manual.

Speaker Level — (Right & Left) connects the subwoofer using standard speaker cable. This set of inputs provides a place to connect the subwoofer using standard speaker cable. To use these connections the speaker cable should be terminated using banana style plugs. The setting for the Low-Pass Filter control is applied to the signal received through these inputs. Please note, do not make connections using both the RCA and Speaker Level Left/Right inputs at the same time.

Low-Level Input — RCA (LFE) connects from the Main Out or Pre Out on your receiver/pre-amp. The setting for the receiver/pre-amp's Low-Pass Filter control is applied to the signal received through this input (the subwoofer's Low-Pass filter is bypassed). Unless you are using a subwoofer where the Right RCA input doubles as an LFE input. On these subwoofer's you'll want to set the sub's Low-Pass Filter to Bypass (or it's highest setting) and then set your receiver/pre-amp's Low-Pass Filter.

Low-Level Input — RCA (Right & Left) from the Main Out or Pre Out (left & right) on your receiver/pre-amp. The setting for the subwoofer's Low-Pass Filter control is applied to the signal received through these inputs.

Low-Level Input — Balanced XLR (LFE) connects from the Sub Out on your A/V processor. The setting for the Low-Pass Filter control is not applied to this connection. Crossover settings for LFE In are controlled through your A/V processor. Please note, do not make connections using both the XLR and RCA LFE inputs at the same time. This input provides the lowest noise and distortion possible. It is particularly important for long cable runs.
