Modelling this in Winisd.
How is a 4th order with an "infinite" sealed chamber any different to a ported box?
Cone excursion models the same, but the frequency response suggests there will be an 8dB gain at 18Hz.
Is this actually going to be the case?
The "port gain" graphs for the two enclosures are basically identical?

The difference is that with a ported box, you're listening to driver & port combined.
With a 4th order bandpass, you're only listening to the port output.

My intention was under the floor, but wall would also work.... depending who/what is on the other side... haha
With a 4th order bandpass box, the tuning frequency is at the centre of the pass band (useful frequency range).
With a ported box, the tuning frequency is at the bottom end of the pass band.
How about a regular infinite baffle setup? That will save you 150 L of box size.
