Yea guys I would like to know the pros and cons of subwoofers sharing the same internal volume. In particular, I built a fiberglass enclosure for 3 ten inch subs, but I didn't chamber the enclosure. The fiberglass enclosure was built out of my spare tire well.
The subs I'm getting requires about 1cubic foot each to work with, so my question is since I'm getting three of them and the enclosure is not chambered should it be 3 cubic feet in volume?????????

Let me know
thanks

 

Yes it should be 3 cubic feet.

 

Thanks man I was just making sure, because I couldn't understand the theory behind it. In a way I still don't, because it seems to me that each sub will be getting 3 cubic feet and not 1 cubic foot. Do you know what is exactly happening with the volume and each sub while it plays? Since its three subs, do each sub takes what it needs????
lol....I'm lost

 

Lets imagine for a second that the enclosure is a beanbag chair, for lack of abetter example. You push on the beanbag chair with 1 hand, it goes in pretty far. Push on the beanbag chair with 2 hands, and they both go in, but with equal pressure from both hands, they will go in the same distance, neither of them as far as the frist.

The box is the same way. The subs are your hands, and with them pushing in (or out) they both compress the air the same (we'd hope so ) and since neither is pushing harder than the other, they compress the air for each other, making it seem as if each sub has thier own airspace.. all the air compresses the same throught the enclosure so all subs see the same air suspension inside the box.

Hope this makes some sense

 

By fu**ing george........ I got it........lol. I see what your saying, I was a little hesitant on purchasing my subs, but now I can go for it. I planning on getting 3 ten inch O's from Elemental designs. I'll post the instal as soon as I'm finished.

Thanks

 

hell yeah when u get that installed post pics man!. What amp r u using to push em?

 

I'm going to be using 2 DEI directed 600D's in an external synced bridge operation. So thats going to be about 1200 watts at 2 ohms or 800 at 4 ohms. So the 3 subs will be wired to 2.67ohms.
