Resurecting this sport
so you tested 4 18s in different boxes?We tested the NS 18 in multiple boxes ...ranging from 4-7 cubes per sub ...and 4-4.5 has been were they shine @ ...so theres really no need to build the box bigger ,when you will have to shrink it up ...
4 of these together are gonna act diffiernt in the vehicle compared to a single box in the amount of airspace it is using. these subs will sufficate and the box isnt gonna allow this system to shine the way it should
