less possible turbulence, more airspace, higher #'s ?

It's easy to change tuning. For SPL, you can change it by simply chopping off some of the aero.

Hm well in my case itd be alot easier to build a box since its so small it needs a really long port so i could save alot of hassle by using an external port. Anyone got a calculator for it?
