Since the subwoofer is responsible for low bass tones (aka its sole purpose), it requires a transmitter of low-frequency audio waves. The left and right channels are combined in an LFE cable to allow for a singular cable to evenly disperse the signals to the subwoofer.
Dual input allows the subwoofer an extra sensitivity adjustment. Normally, it would be enough to use a mono LFE subwoofer signal from its processor. By using both inputs with the same mono signal doubles the subwoofer sensitivity. This means that there is now only half the signal strength to drive it to full output.
Does a subwoofer need left and right?
Most subwoofers have both a left & right input. It usually doesnt matter which one you use. Some people will buy a “Y adapter” or “splitter” so that a single cable can feed both subwoofer inputs.
Does it matter where the subwoofer goes?
Typically, you position a subwoofer along the front wall of the room. Many vendors recommend that you place your subwoofer in a corner. This placement reinforces the bass significantly. However, in some rooms, you can get too much reinforcement of your bass in the corner, and you end up with boomy bass.
How do I connect my left and right subwoofer speakers?
If the subwoofers Line In uses RCA cables (and if the subwoofer out on the receiver/amplifier also uses RCA), simply plug using an RCA cable and choose either the R or L port on the subwoofer. If the cable is split on one end (a y-cable for both right and left channels), then plug in both.
Can I put subwoofer under bed?
A subwoofer can be placed on or under a table, behind the television, and on the floor in a corner, depending on the floor space and listening area. However, it is not advisable to place a subwoofer under a bed as it can hinder the subwoofers output.
Can a subwoofer be behind a couch?
While subwoofers are often placed in the front left corner of the room, putting a subwoofer behind the couch (as long as it remains 25-35cm from the wall) can be optimal and help with localization. To test the best location for a subwoofer in your space, use an SPL to measure frequency response.
How do you hook up multiple speakers to a subwoofer?
What to KnowEasiest: Connect one receiver output to one subwoofer and the second one to the other subwoofer.Next easiest: Use an RCA Y-Adapter to send two parallel low-frequency audio signals to two separate subwoofers.9 Mar 2021
