Ok so I'm pretty sure I already know the answer to this buti just want some other opinions.
10.5 or so cubes net, currently has 2 full length 6" aeros. Moves TONS of air a day does a semi decent number with relatively low power. Was originally designed for 3 but had a slight change of plans.
With the 2 6" we have roughly 5 square per cube, with the 8" ones we will have roughly 10 square per cube and tuning is bumped to 33 hz.
Should SPL increase? If so by how much (estimate)? Will the lows still be as pronounced? Will it move more air? This is assuming everything else stays the same.
