The phase control operates over a range of
0 to 180 degrees
. Adding delay to the subwoofer signal can sometimes help the subwoofer to integrate better with the loudspeakers in the room. Setting the phase control to 180 degrees reverses the polarity of the subwoofer.
What are the best settings for a subwoofer?
- If you know your speaker's frequency range, set the crossover point roughly 10 Hz above the lowest frequency your speakers can handle cleanly.
- The most common crossover frequency recommended (and the THX standard) is 80 Hz.
What's the difference between 0 and 180 phase?
Typically, though, phase is left at 0° for most applications. While seated in your listening sweet spot, play music with bass content that is familiar to you and then have someone switch the 0/180 phase switch on the sub to
180-degrees
. This will let you determine if the bass sounds louder in your seating position.
How do I know if my subwoofer is out of phase?
If the sub and mains are out of phase,
the woofer cones on the main speakers will move backward while the subwoofer cone moves forward
, and vice-versa. They'll cancel each other's output.
What volume should a subwoofer be set at?
With regard to volume, a common mistake is to crank your subwoofer's volume dial to its maximum setting. Instead, set the volume dial to
about 75% or so
and adjust the subwoofer output level from your A/V receiver or preamp/processor instead.
What is 180 phase subwoofer?
Setting the phase control to 180 degrees
reverses the polarity of the subwoofer
. In some application where the subwoofer is placed on a wall opposite from the speakers, reversing the subwoofer polarity can yield better in-room low frequency response.
What's the best LPF setting?
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.
What should LFE be set at?
The LPF for LFE is the low pass filter setting for the LFE channel. Normally this is set to
120 Hz
, since that is typically the upper limit used by DVD mixing engineers.”
What Hz is best for bass?
Bass:
60 to 250 Hz
The fundamental notes of rhythm are centered on this area. Most bass signals in modern music tracks lie around the 90-200 Hz area. The frequencies around 250 Hz can add a feeling of warmth to the bass without loss of definition. Too much boost in the bass region tends to make the music sound boomy.
What should LPF for LFE be set at?
In practice this should always be set to
120Hz
since the LFE channel supports information up to that frequency. When you set this lower than 120Hz the receiver or preamp will not redirect the LFE information to other channels.
What does it mean when subs are out of phase?
The most common symptom of a speaker or subwoofer that is wired “Out of Phase” (when it shouldn't be) is
loss of bass
. … Listen to the bass, then change the balance to the opposite speaker. If your speakers are out of phase, you will notice more bass response from one speaker than the other.
What happens if speakers are out of phase?
Wiring speakers “out of phase” will
“destroy” imaging — sounds
that should “center” between the two main speakers might sound very diffuse, instead — and can cause the apparant sound level to be diminished (weakened bass, for example).
What does it mean when speakers are out of phase?
“Out of phase” typically means that
one source is “contradicting” what the other source is doing
. When a speaker produces sound, it is vibrating back and forth. … If your speakers have the positive side of the speaker wire connected to where the negative should be, they will be out of phase.
Do subwoofers get louder as they break in?
No, that's normal, especially subs with stiff suspensions.
Once they loosen up
, they will play louder and sound better.
Can you put a subwoofer 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.
Can I put a subwoofer next to couch?
Can I Put a Subwoofer Next to My Couch? Absolutely. It's a favorite spot for a lot of people. A good place for the subwoofer could be
in a corner
, near the armrest of your couch.
