Building a hush box for Amps and Transformers. Thoughts?


Active Member
I need to build a hush box for my HT subwoofer amp and the step down transformers that power the LED lighting. All this stuff is in a cupboard outside the viewing room but it still sounds like a jet engine'd aircraft is taxi-ing in the hallway.

I get the basics, i.e a push-pull airflow design with low noise large diameter fans and some foam stuck inside, but I was wondering if anyone has done something similar and if there are any tips/suggestions before I start?

The amp is 19" rackmount and the transformers are various sizes. I plan to put them all in the single hush box.
