what happens if you load the output of a active sealed subwoofer into a horn that is 8 feet long something like the coffin sub ?

Ooo a twist on a 4th order bandpass design not normally found in cars as they prefer the smoother 6th and higher order designs.

Without doing the mathematics (do they exist?), and not using the correct drive unit it'll be a disaster.

You'll probably get a collection of funny noises due to the ragged response of the design until the larger excursions tear the drive unit apart Sad .
