i have been told to put the 45 degree angle wood pieace in the corner leading to the port

and to put PVC piping in my port.





also i have been told to resin inside the box do a few layers
what else is there . and will these for sure inprove

like this?

i put them in my box and i gained quite a bit

it can help and it can hurt...theres nothing for sure

I have both lost and gained in different applications from each of the changes you mentioned above. Only way to tell is to test it out on a mic.

Christmas Tree air-fresheners are the only garuanteed DB boosters. :)

Vanilla christmas tree fresheners to be exact lol

I'm guessing it all depends on the size of the box.

In my testings, I agree with the some it helps some it hurts, Test, Test, Test, only way to be sure :D
