View Full Version : Sub placement against the wall
10-30-2002, 08:26 PM
I need to know if it is better to place your sub right up against the wall so the ports fire directly into the wall. should there be space in between the wall and your sub and if so what would the optimal space one should leave in between?

Near the wall will yield the most bass reponse, in a corner even bigger sound.
How close is too close? I'd say leave at least 3-4 inches.
When in doubt we experiment.
"yes yes Igor I'm coming."
Got to go.
Play with it , put it where it's sounds best to you.
Too much boom? move it out from the wall some, or use less nitro glycerine in the mix.

i like to have mine placed about 6 inches from the wall..it yeilds best results for me.
As trubluluc says...experiment. Listen to your ears....

everyroom is going to react different.I'd start with a front corner install,keep it away from the wall,a foot should be ok to get started.....then start moving it up and down the sidewall in 1 foor movements.If worse results occur,try sliding back and forth across the front wall,in small 1 foot steps.
Then the phase switch.........or placement in the front 1/2 of the listening room,I have found leaving it in the 0 position seems to work out the best.After the 1/2 mark,then phase seems to be needed........

i know this is going to sound funny but i never fully understood what my phase switch does. is there a noticable difference between the two setting. and if so what exactly does it do? and thanks for the help with the sub placement

Yeah please tell me. i have no idea either. I have tried to flip it back and forth and I can't personally tell a difference.

i dont' know the difference either. but on my 350... one flip makes is sound just a little bit louder bass.

i know one flip but what way? normal or reverse?

The phase switch is used to minimize the effects of standing waves. Basically, depending upon your speaker/sub placement, sound waves will cancel each other out.
The result is less bass impact.
Reversing the phase prevents the sound waves from cancelling each other.
Bottom line is, whichever sounds best to you is correct.

LOL.....speaking of a phase switch, my old 15 year old M&K..dont even have one...so ya'll should feel really special right? lol....i thought that was kinda funny....lol

A subwoofer will sound good if there is some air between it and any walls nearby. Bass sound is omnidirectional and travels in all directions. thats why when placed in a corner it seems to be louder. Since bass freqs are long waves you use the phase switch to invert the wave hitting you near where your sweet spot is(the place in the room you have determined is the optimal listening spot, where you should sit). Play your sub, and walk around the room...see if you hear it more at the back of the room, or you hear it more at your sweet spot. Switching the phase will change where the wave falls in the room.
