It is funny to see that plastic tubing used for ventilation purposes :)… You have probably limited airflow a lot with including that foam rubber inside… Does it really work?

Why did you choose plastic? Isn’t it better to use sono-flex for all ventilation to keep noise low… ?

What is funny? Do you know that the whole assembly boxing comes from us from building material?
