The advantage of a PiAligned 2206 vs. one that's 3 cubic feet is that the PiAligned cabinet is flat down to its lower cutoff. You can expect this from cabinets of about 0.75ft³ to 1.5ft³ tuned to 60Hz. But if deep bass is desired from the 2206, then other alignments might be considered. An advantage of a larger box is deeper extension. You can expect output down to about 35Hz in a 3ft³ box tuned to 35Hz, but it will be an EBS alignment with the lower bass shelf reduced some 5dB from the midband amplitude. This is a pretty good alignment where deep bass is required from a 2206.

One alignment favors full range performance and the other favors deep bass, but both are acceptable design choices. Another good option would be a compromise solution: JBL suggests this in their product documentation - A 2ft³ cabinet tuned to 50Hz.
