SMD Father & Son Project Eqiupment question

[Soundgenerator]

Hi guys,

My Name is Lars. I'm 21 years old and I'm from Germany (sorry for my bad englisch ?)

i have a question about the Father & Son Project.

Father & Son #5 Mids and Tweets

At 4:08 Steve puts a weird case behind the midspeakers. I've never seen this before and a few others (from another german Forum) have never seen this too.

Where can i get a case like that and how is it called?

 

Thanks for every answer ?

- Lars
