Opinions on sealed vs ported

[Joe X]

For a dual Zv3 18 setup there's enough space in 43x40.25x18, dual 0.75 layer all around, final specs could get are 9 net@ 32.5Hz, 154 square inches of port area (estimated peak airspeed 18m/s @ 3400W total power ). For (most) 18s working in larger airspace this wouldn't be possible.
