i need to understand at least a little
what is happening with bipolar?

and about softwares when desinging the box,
no one offers bipolar option, what should i take in consideration?

and also, if i put 4 drivers in the same box
2 pairs in bipolar kinda config .. wonder what it would do!

Well, i sort of implied you can't build a bipolar sub, because even a single woofer is omni-polar. The advantage of using a bipolar cinfiguration to build a push-push sub that gives you active force/vibration cancellation improving downward dynamic range, reduced transmitted vibration to the box, and no problems with seeing your sub dance.

well that's the kind of good information i'm looking for ..

so is it worth it to use bipolar config on sub?
what are the cons?

i am expecting largrer volume enclosure required ..but not 100% on that one..

the + and -

implications .. drivers requierement

is it good in use for sub?

====

Already answered.

>for mid?
frequency related problems?

No, though can work well if a more diffuse soundfield is desired.

>enclosure design considerations ( volume? )

For a given alignment, Vb doubles.
