Hey guys, I'm new to the site. I am about to build a new box for my Fi BTL 15'' and I was wondering what aero ports are? I know this may sound stupid but basically what I want to know is if they can be used instead of a slot port in a ported enclosure that will be used daily for music? Can you still pick a tuning frequency? I was looking to tune at 32hz with a box volume of 4.5 cubes. And lastly, is there a benefit to them over a slot port design? Thanks!
