one your request on a double horn 46" high,
can it be done ? shure but,
the box wil get a lot bigger and heavier.
its going to be less efficient.

Epa thanks for trying to help me out. I guess for this design to work the box size has to be very large. i was aiming to move more air with few box as possible, i guess it wont work with this driver.

what do you think of 2 push pull lab12 in a tapped horn playing 35hz to 100hz
