i wanted to install soemthing like this, https://my350z.com/photogallery/show...to=440&cat=563 it looks hot, but do you lose any base because of the air space, or actually gain it? thanks!

 

that is designed with more attention on presentation

less on numbers

so you sacrifice some SQ and SPL


if you want it to look good go for it

there is a happy medium , you can get something to look great , and get good SQ and SPL
