6th order? Coffee table?

[Tony_stewart07]

There's been some discrepancy about what order my coffee table is, there's 4-10" subs DVC 4ohm face to face running in 8ohm load to my home stereo, it ******* rocks!!! But what is the proper name for this??

Isobaric 6th order bandpass. One ported section or two?

 

[Tony_stewart07]

4 sections each ported

Yes, 6th then

Looks like just 4 individual ported boxes. A 6th order is a ported box firing into about ported chamber... Yours doesn't have that going on. Yours looks just like 4 ported boxes.

No, that's a quasi sixth where a ported box is inside another.

This is a different type of sixth

That's not how it is though. It has 4 separate chambers and each one is ported out the side... That's what I see in the picture

Question is, what happens to the beverages when that puppy is at full tilt lol.

Actually, after looking at it again, this is exactly what it looks like:

Derp, you're right.

Like this one, but isobarically loaded

Still a sixth, but isobaric and not quasi, my bad

It's called a parallel 6th //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

And I can't tell if it's that but if both the front and rear chambers are firing into the environment, it's a parallel 6th.

Yea I'd call that an iso 6th. It also appears to be a 1:1 ratio but with different tuning. Not something I've ever seen before. Typically iso is used so that small airspace can be used. I wonder why not just use a 4th or standard 6th since a coffee table could offer plenty of space.
