Okay, I was originally making a bandpass enclosure for a 10" sub ... while having another on the shelf in free air. Until I saw one of the designs on this website which inspired me to think of the box given in the picture. The design in question here is the " Isobaric - Bass Reflex (Compound Loading) " setu

What kind of a box would you classify this  as ... a sealed + bandpass ... or ported ... ?

would this enclosure combination work? -- posted image.

Yup. This box would work provided the parameters are for the proper sub. This is an Isobaric - Bass Reflex Setup with Compound Loading settings. It's design makes for a fairly large box and needs a higher level of fabrication to get this to work right. So long as the speakers are phased with each other, they're fine.

Arite thanks bro.

Would I be better off with this combination. Or to simply make a bandpass enclosure for one subwoofer and freeair the other one ?

Id put both in a bandpass, but since I dont have any midbass I'll be having a lack of sound in 100-150Hz range.

First off, I'm not your bro... I'm your sis ^-^

This is a rather complex build and it tends to get very big, so I do not recommend this style of box often. It would rather depend on what kind of sound you are looking for... Bandpass boxes are excellent if the box is made for the specific subwoofers only.

... ahh ... sorry about that dudette lol

Well, yea ... ill build the box for the intended subwoofer ofcourse. 

Jus one thing, you'd recommend making a bandpass for both subwoofers, or running one free air and one bandpass ?

You don't want to run two subs in different enclosures for sure.  The box you are describing is going to be very difficult to build correctly as well.  You may be better off going sealed or a simple ported design.

Ahh yea ... Ive decided to either make 2x bandpass ... or 1x bandpass and 1x sealed/free air depending on the subwoofers compatiability!

Ok but i hope you know what you're doing because if you're guessing at the dimensions of this thing its going to sound terrible.

it's not going to sound bad so much as it will live up to it's name, "The Speaker Destroyer"

Bandpass filters the frequencies you would normally hear (in my experience so please no flaming me on this) when your subs are distorting and destroying themselves. By the time you hear the destruction in the subs, it's usually too late to adjust the output and usually it means replacement.

I would just consider going for a ported setup.
