Can You Connect Speakers to a Subwoofer?
The simple answer is: it depends on the type of subwoofer and your audio configuration.
Connecting Speakers to an Active Subwoofer
Active subwoofers usually feature both low-level and high-level inputs. This capability allows them to be integrated into various audio systems more easily.
Using High-Level Inputs
If your active subwoofer has high-level (or speaker-level) inputs, you can connect your speakers directly to it. Here’s how:
-
Identifying Speaker Outputs: Locate the speaker outputs on your AV receiver or amplifier.
-
Wiring: Connect the speaker wire from your receiver to the subwoofer’s high-level inputs. Be sure to match positive and negative connections to maintain phase coherence.
-
Connecting Speakers: From the subwoofer’s speaker-level outputs, run wires to your main speakers.
This setup allows the receiver to send the entire audio signal to the subwoofer, which then splits the frequencies, sending low frequencies to itself while directing higher frequencies to the connected speakers.
Using Low-Level Inputs
In setups featuring an AV receiver, it is generally better to connect your speakers to the receiver rather than directly to the subwoofer.
-
Using a Subwoofer Output: Connect a cable from the subwoofer output of your AV receiver to the line-level input on your active subwoofer.
