What does phase 180 mean on a 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.

Which way should I point my subwoofer box?

Facing Upward – Towards The Trunk Hatch Facing the subwoofer upward while in the trunk, gives you big bass without consuming a lot of space. This direction offers crisp sound with a slight advantage to high frequencies and treble, and won’t rattle loose parts in your vehicle as much.

Does the depth of a subwoofer box matter?

Registered. For sealed boxes, especially, the shape doesn’t matter. What matters is the size/volume. Depth matters if the subs vent through the bottom of the motor/magnet.

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 is 180 degrees out of phase?

“180 degrees out of phase” means the zero points remain the same, but when one signal is at its peak (maximum), the other is at its trough (minimum). In other words, when the green wave is at 0° phase, the blue wave is at 180°.

How big should a subwoofer box be?

According to the JL Audio website, the recommended volume space for a 12-inch subwoofer is 1.25 cubic feet. For a 10-inch woofer, the volume recommendation is 0.625 cubic feet, and the recommendation for an eight-inch speaker is 0.375 cubic feet.

Why does my subwoofer have a 0/180 phase switch?

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. To check your sub’s phase, play music with lots of bass, listen for a minute or so, and have a friend sitting by the sub flip the sub’s 0/180-degree phase switch slowly back and forth.

How far should the subwoofer be from the speakers?

With small speakers, it’s best to keep the sub within 3 or 4 feet of the front left or right speakers. Once the sub is a lot farther away, it will be harder to maintain the illusion the bass is coming from the speakers.

How many degrees of mains and subwoofers are in phase?

Depending on the positions of the mains and sub, you would get varying degrees of each at different locations within the room. In the MLP you may be in-phase with the main speakers (in-phase 0 degrees) but in the sub’s Trough or some degree varying between 0 and 180 causing some cancelation of the resultant total signal.

What are the different subwoofer settings on my Receiver?

On some receivers you’ll be presented with a wide range of subwoofer or crossover settings, from 40Hz up to as high as 250Hz.
