You mean Isorbic ? with one sub mounted on the face of the other ?

 

The Concepts on Wheels show had some pictures of it I believe. You'll have to find them somewhere on the site.



It has some pictures in there somewhere of what you are referring to.

 

heres one

 

What are the pros and cons of mounting subs this way? (like in the above pic)

 

pros: if you like the back of the sub...you can see it.
cons:sub box will take up more space due to odd dimensions.

 

Does the sound quality change when this done on a sealed box? Or how about ported or both facing reversed? I've never tried it.

Thanks!

 

yes , it's supposed to get better with 1 sub inverted , let me remember and I'll post again when I do .

 

The only sound diffrence will come from the added internal volume of the box from not having the magnets in it. In a ported enclosure this will result in a lower tuning frequency, and in a sealed box a lower Qtc or flatter response curve. I have also heard that at very high volumes the voice-coil vent could whistle, but this could just be a rumor, and if it is in a trunk you shouldn't have to worry bout it. Just make sure you have the subs in phase.

Check out this thread I started a little while ago.

 

u get alot more box space when you mount them inverted and when u get more box space that means the louder it is so unless ur box is made perfect righ size to ur subs inverting them will make them louder
