Sub install question

Hi,
I have seen many people installed their sub reversely, the magnet on top like Michael in our forum.
What diff between that installation and the normal installation?
On my HU, it got the setup for sub to be reversed.
And how much volume do you build for that kind of reverse box?
I love the look of my sub magnet :D so I wanna build it like that :D
Thanks :cheers:

the only diff between regular install and reverse is you get to see the back of the sub and not the top...installation is the same as is the required enclosure size.

Minus speaker displacement. Which isn't really much at all, even for a JL W7 :eek:

Awhile back I inverted my 2 12's and got a much better sound. I feel that was do to a small gain in air space from the enclosure I was using.

Don't forget to add the volume inside the cone to the enclosure volume. A rough calculation should be sufficient to give you some idea of what that volume is.

Re: Sub install question (Metal_Wulf)

Depends on the box. Just doing some rough calculations for a 12" speaker, I'm getting somewhere between .1 and .2 cu ft. If you're running a 1.5 cu ft box, it's not that significant, but if your box is only .5 cu ft, you may want to account for it.

I figured the volume using a cone with a radius of 5 inches and a depth of 2 inches, then guesstimate how much volume you lose due to the dust cap in the middle.
