inverted subs

[SOMbitch]

i recently bought 2 Alpine Type R 12" subs and im building a custom box to fit my car, my question is, can i invert these subs? if so what kind of box would i need to build? ported? sealed? some other kind? thanks

yes you can invert them and it doesnt matter what enclosure you build for them

yeah...what the rotten apple said!!

[hybrid90accord]

you can invert them just rememeber that because your inverted the woofer displacement will be different so you will have to calculate that into your equation when building the box.

and dont forget to reverse the positive and negitive on the subs

it will put to rest a few rumors about inverting subs etc etc etc

only time you really need to do that is when you have subs both ways, inverted and normal.

please pay DJ XtRaK no mind with his bad advice ,,BanginJimyy is correct on this one!!
for that matter polarity dosent even matter ,as long as they are the same on both subs

You can invert any sub. They dont sound any different inverted, its just for looks.

yea you can invert any subs but different subs sound different. like if the sub required a lot of air space then you could cut down the air space and port it and it would sound pretty good but like every one else said either way it will not really make any difference..

I would disagree with that statement.

There is DEFIANTLEY a sound difference. Most people dont have a good enough ears to know what they are hearing, but its there.

Granted, it is VERY slight, but it can be there.

I've noticed a little bit of a flutter with inverted subs in a ported box. Never heard a difference in a sealed one though.

my brother had a set up like this in his 280z it was awesome.he had 2 12's in one box but the subs were mounted together with cones facing each other one was in the box the other inverted(magnet up) and set out of phase so when one pushed the other pulled that way they would not slam into eachother.this was proably one of the best sounding systems as far as bass goes ive heard if not the best with only 2 12's and a fairly small amp.
