Should my sub phase be 0 or 180?
Typically, though, phase is left at 0° for most applications. The more bass-heavy setting is where the output of the subwoofer and the main speakers are most in phase. Use whatever position (0/180) is louder at your seating location.
What phase should I set my subwoofer to?
One of the other controls you may find on your subwoofer’s rear panel is marked “phase.” It’s provided because the speakers and subwoofer sound best when they are in-phase — meaning their woofers move in and out in sync with each other.
Why would a subwoofer be out of phase?
So when the positive signal goes to the speaker, it pushes the subwoofer forward. When the signal sent is negative, the subwoofer pulls backward. When two woofers are mounted in the same enclosure and one woofer is inverted, you would need to wire it “Out of Phase” in order to make the sub perform correctly.
What does 0 and 180 mean on a subwoofer?
The phase control operates over a range of 0 to 180 degrees. 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.
Does subwoofer need time alignment?
“Time alignment is not important for woofers because of the length of the wave. say the diffference between having the sub up front and in the back is 5 feet, and sound travels at 1100 fps so it takes an extra 4.5ms for the sound to reach your ears if the sub is in the back than if it is in the front.
What happens if 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. That’s because the phase of both devices changes with frequency.
What does subwoofer phase 0 or 180 mean?
We explain what is meant with phase control and the term – subwoofer phase 0 or 180. Phase control or phase setting, as it applies to a subwoofer, refers to the signal delay. It is an electrical instruction and operates from 0 to 180 degrees.
What is phase control on a subwoofer?
Phase control or phase setting, as it applies to a subwoofer, refers to the signal delay. It is an electrical instruction and operates from 0 to 180 degrees. When set correctly it allows the subwoofer to integrate and operate better with the rest of the speakers in the system. Much depends on the space that you are using the speaker in.
Why can’t I see phase response in Rew?
At the very beginning you will soon realise that it gets much harder to get phase response displayed correctly in REW as your distance between microphone and speaker gets bigger. If you measured from 10cm distance chances are you would not need to apply any gating and/or frequency dependent windowing to show pahse correctly.
What Rew version do I need to align my subwoofers?
This requires either data with accurate phase data, i.e. requires REW 5.15 beta3 or later for access to the acoustic timing reference or use of a physical loopback. Why should I (time) align multiple subwoofers (drivers)?
