Default loading the closet..

i just recently moved and have been having serious problems
with the placement of my subs. no matter where i moved them in the new room.. i just could not acheive anything near the absurb room gains i had in my old room. that was until i stuck the sub in my closet.

my question though is what's the best way to load a rectangular closet..

do i

a)place the subs in middle of the closet facing the narrow walls

b)place the subs against the narrow walls facing the middle


c)place the subs against the backwall facing the closet opening.

d)place the subs at the closet opening facing the backwall



any suggestions?

Someone may have advice for you....

But this is definitely one where you will eventually have to try it yourself anyway, so you may as well start now...

Default trial and error..

i just tried a couple positions..

one thing was wierd though.. is this normal

when i had the subs facing each other, each had to be at
a 180 degree phase difference just to sound clean.?

I think I need to stop trying to be funny. Ive been causing too much trouble.

Is the closet door open or are you thinking about making some kind of sofit or baffle? Could be that the volume of the closet with the sub in the opening is causing as much cancellation in some frequencies as gain in others. Some comb filtering perhaps?

Is the room furnished different from the last one you were used to? I've found that very bright rooms (lots of hard surfaces) tend to sound base deficient, as there arenít as many high frequency absorbing surfaces. A chunk of carpet of the floor can cure a lot of this.

I think its neat what you are trying to do with the closet, but in the end, I think that comb filtering will cause more problems than you will get benefit from. If the closet has a louvered door or is in some other way unavoidable, that becomes a different issue.

Dual subs can give you a lot of issues with room geometry, as you seem to be finding. They will couple and cancel at different frequencies, again causing a comb filter effect and weirdness with the phase control. The most accurate thing to do might be to work with them stacked or side by side, and then start going through combinations of forward facing, facing apart, in phase, out of phase.

Iím goanna get beat up for making a lot of guesses here. Its kind of tough to tell what your up to without seeing it.

Default problem solved...

i tried every stacked / side by side combo closet but still no real
improvements.

one sub alone still sounded cleaner than both subs and both subs played into room unevenly with couplings/cancellations all over.

one thing i did notice is with all the trial/error combo's the bass in the room corner opposite to the closet hit pretty well.

then it hit me.. one sub in the closet the other in the opposite corner..

i tried it out. it worked like a charm...

nice clean even bass...
