Im trying to decide if a push pull speakers setup or what i think is the tech term resonant reflector. I need to know specs and the formulas that go with building a speakers box

I think what you are talking about is called isobarik. A technique that uses opposing drivers to half the amount of airspace used for one, with a decreased amount of distortion produced. Can be applied to almost all applications (sealed, vented, etc). The big con is that output will only be that of a single driver.

The Isobaric design is good when you have a very small space to work with and need a woofer system to handle more power than a single sub can take. It's not a very efficient design either, as output SPL is equal to whatever one sub can produce at rated power.
It would be better to use a single sub that can handle the power required and save the $$ an extra woofer would cost.

There is another type enclosure that is actually called push-pull or symmetrical loading if I recall. This differs by way the drivers are positioned and does not decrease airspace. In most cases, it is increased.
You might have seen a few bandpass boxes setup like this in the past and a few still are today. A very complex design for a novice and most experienced still. It's main focus is to cancel out distortion with a higher output in a given range.
