GM what about a4 to 5foot high mass loaded transmission line?
Greets!

Yes, this is what I had in mind, so using published specs (all dims are inside):

L = 56"
CSA (width x depth) = 75"^2
driver down = 19.42"
vent = 3" dia. x 7" long
suggested stuffing = ~24 oz of polyfil evenly distributed from top down ~45"

This sims a near IB response, so unless up against a wall it will probably need some BSC, and even then the bass will roll off below ~80 Hz.

Note though that the specs don't match up all that well with calc'd ones, so you may want to try a 3" long vent also before adding any BSC.
