does it matter the way the subs are placed in a box, does it matter if they fire in or out of the box, whats the real difference between the 2, just looks? or is there a purpose? does it matter if 3 subs are in 3 seperate chambers 2 fireing out 1 fireing in? or is it something only done if a box is made with 1 big chamber?


....isnt it obvious im trying to build a custom enclosure haha

one other thing... its 3 jl10w3v2 subs what would be better ported or sealed box

 

i don't know that much about that... i got mine moth subs firing out not in but it is for special purposes like ported bod and non-ported depending what u need for your setup both sound different...... i might be wrong but thats what i was told a long time ago... i got sealed box and i think it's better off for each sub to have it's own chamber ..... u got to make it in the right dimensions though for the best sound......

 

yea i knwo the demensions are key for good sound....i just love the look of the inward fireing sub and want to find out if it will make my sound worse by doing that

 

no i don't think it will be worse i think it's the same as a ported box?? IMO i might be wrong

 

As far as I know, there's no difference between subs firing in or out, as long as you take into account the additional volume by firing in, and that you make sure to set the sub 180 degrees out of phase. If you have 2 firing out and 1 firing in, I'm sort of interested to see how you would do the in phase for 2 and out of phase for 1, as don't amps generally just have one phase correction adjustment? It seems like you'd have to have at least 2 different amplifiers in this configuration (probably different sizes)

 

what do you mean by phase, i know the ins and outs of doing a basic stereo install but this time im trying to do things differnt. do i have to worry about these "phase" if i have differnt boxes for each sub(what im planning to do)

 

You kids are making this way too complex. Lets start with the difference in ths sound of firing in or firing out, inverted or normal. The primary sound difference will be chuffing from high speed wind around the basket. Some subs are designed with a baffle for dipole use and will not suffer as much ill effect inverted. Other than the nearly inaudible chuffing is the matter of sub displacement volume. This must always be factored in when building a sub box. When inverting the sub don't bother with adding the exrtra volume for sub displacement.

As far as the other thing that is polarity. When you mount them inverted the sub will need to move the opposite direction of a normal mounted sub. In other words you need to hook it up with the positive and negative wires reversed. Of course you must consider the fact than optimal sound might not be achieved with the subs wired in phase. But all the subs, in this configuration, need to be wired to push the same direction at the same time. In other words all need to be pushing into and out of the box as one.
