Is there a way to test that a box is completely sealed?

I have pretty much finished my enclosure. It is a 3/4" MDF box chambered for 3 10" with .75cuft per sub. I used a sealant adhesive during construction, and a [censored] load of silicone on the inside. Is there any test I can do to check that it is sealed so I can go ahead and wrap it with my vinyl. My subs and amp should be here in the morning and I want my enclosure to be ready!

MDF is breathable anyway, so there is no real way to test other than visually looking and then installing the sub and listening for air. playing low frequency tones (30-40Hz) is a good way to listen for air leaks. i would install the
if you have a continuous bead of silicone along all seams, you are good to go.
however, given the time line, you should test with the subs first. that way you know your holes are of adequate size.

if the box is sealed, when you push down on the cone, you'll feel a decent amount of constant pressure and the cone will slowly sink in and slowly return to it's normal position.
if there's an air leak, the cone can be pushed down easier and it'll spring back to it's normal position pretty quick.

You could drill small holes in your box and as long as they don't whistle, you'd never know the difference... being "sealed" is really just a way to say "not ported on purpose". As long as you do a decent job with your cuts and your construction, you'll be fine.

i use the push test on all sealed boxes, you will know right away
