2-6's or a single 8 are much much better options.

4-4" aeros = 50.24 a single 8 equals 50.24 but is much more efficient a single aero is much more efficient than multiple ones plus is alot easier to tune and change the lengths.

I had a box with four 4" aero's for my MT 18 - burp box though. Now I have a bigger box with two 6" aero's for my DD9518. both work fine but ease of use goes to the 6"ers due to me trimming the inner flare to fit through the mounting hole.

my only problem is the 6's are too tall and i dont have enough height on my box to clear the motor. that is a pisser.

Get more port area for a SPL box. That is, if you're tuning high for burps. Depending on what you're tuning to you can get a lot of port area without needing to give up much box volume due to port length. I used to run 180-200in^2 of port for a single 21" sub a few years ago in a 52hz burp box.
