[*]Stackability: I want to be able to stack the array on top of them when Flying the array is not practical. I am defiantly looking at using PTFE (teflon) strips on the bottom with grooves fro stacking. [*]Truck Pack friendly: To me this means a rectangular box not a trapezoid, that has dimensions that add up to just short of 90” when packed side by side in at least one direction, bonus points for 2 directions. [*]Portability: How am I going to attach wheels? [*]What I am not concerned with is getting all the way down to 30hz Most of my work is bands, not EDM so I am perfectly fine with great performance from say 40-95 hz [*]Price: To say it is of no concern would be a lie, after all I am trying to save money not buying a commercial sub.
