How do you adjust phase alignment on a subwoofer?

How do you adjust phase alignment on a subwoofer?

Align the phase of the main speakers and subwoofer Return to the center seating position in front of the main speaker and subwoofer. With your head placed equidistant from each, slowly rotate the subwoofer’s phase control knob clockwise and notice the bass drop off significantly, then begin to rise.

What does phase control do on subwoofer?

The phase control in a powered subwoofer allows the user to add electrical delay to the incoming signal. 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.

How do I know if my subwoofer is out of phase?

If the sub and main speakers were in phase, he’d hear a single thump when he connected the battery to the wires leading to the sub’s terminals. If they were out of phase, he’d hear a double thump. That’s with passive subwoofers, though.

What phase should my subwoofer be set at?

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.

What should crossover be set at?

Set the crossover point around 10 Hz below the lowest frequency your speakers can produce without issue. (keep in mind that the most common recommendation for crossover frequency is 80 Hz).

How can I make my subwoofer sound better?

Just follow these simple steps for great bass:

1. Remove the distortion.
2. Flatten the signal, open the low-pass filter.
3. Adjust the subwoofer gain and low-pass filter.
4. Adjust the bass boost and subsonic filter.
5. Match the subwoofer level to the receiver volume.

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 happens when speakers are out of phase?

Registered. 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 should I set my subwoofer low-pass to?

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.
