For the issue of phasing, the common "best" approach is to have the subs as far back as possilbe near the rear wall. Also realize, that you can face the subs toward the rear wall, up, toward you, or even sideways. Here is the short answer. For the best sound quality, the subwoofer should be placed with the speaker facing out to the room, and the port should be away from a wall. Bass waves travel in all directions, but it's important to have the speaker facing your main listening area. 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. if your sub box it tight against the rear seat so no air can go backwards, you'll be fine. if not, it will be better to face them backwards. this is because waves aren't being directed anymore. If you install the subwoofer box correctly, it should be securely fastened behind the rear seats and tucked away into the corner. This provides stability when taking sharp turns or in the event of emergency braking.
Turn the subwoofer amp gain all the way down, turn the low-pass filter all the way up, and turn the bass boost off. Turn the head unit on and set all of the tone controls to their middle settings. Play a piece of music you are familiar with that includes high, mid-range, and very low notes.
Only the Strong Survive. inverted is the correct term to use with that type of set-up. and it depends on the system, if you use 1 amp per sub and run like 2 subs, then a regular facing and inverted facing sub system would hit harder then both of them facing out.
You can place the subwoofer behind your couch. The subwoofer will be close to you when you will place it behind the couch nearby to the wall. As a result, you will get a better sound and bass from it. This position of the subwoofer will give you smooth and deep bass than the other positions.
A subwoofer with a lower electrical resistance produces a louder sound than one with a high electrical resistance, which means that 2ohm subwoofers are louder than 4ohm ones. Although louder, 2 ohm subwoofers are also more likely to produce a poorer quality of sound due to its' power consumption.
Step 4: The Amp Turn the Gain/volume knob to zero or all the way down. Play a song with a middle amount of bass. Not too heavy not too light. Turn the volume on the head unit to 80% of its max volume. Increase the Gain/volume until the sub begins to distort. Slightly decrease the gain to remove remaining distortion.
A subwoofer behind you should be limited to a much lower roll off/crossover point to avoid localisation of the bass. A subwoofer or speakers near any wall will put far more energy into that wall than if it were on the opposite wall or any other wall of the room.
Is sound supposed to come out of a subwoofer? Only if it is on, and the volume up. Subs are speakers, so, yes, they will produce sound when there is something within their bandwidth to be played.
The difference comes down to driver direction: If the subwoofer's driver faces down towards the floor, it's called a down-firing subwoofer. If the driver dispersing its sound through the front of the cabinet, it's front-firing.
Usually you'll know if your system is distorting when you turn up the volume, and it does not seem to go any louder. It just gets more compressed from that point on. And the level of "static" increases as you keep turning the volume ****. Input stage distortion is much harder to hear.
for maximum bass the subs are usually placed in the trunk facing the lid. this is because Subs run off air (obviously) and prefer reverberation (sp) to make "louder" bass. the longer the path of travel for the air is, (with in reason) the louder the bass will sound.
The most effective ways of hiding your sub include: Place it behind the curtain. this is probably the easiest way to hide your small 6x9 speaker from the view. Hide it inside the cabinet. Tuck it under the furniture. Go in-wall. In-ceiling placement. In-floor.
Sealed enclosures reproduce the low frequencies more accurately than ported enclosures because the air inside the box acts like a shock absorber, allowing the subwoofer to move back and forth in more control. Sealed enclosures are generally smaller and easier to build because there is no port to tune.
