Wide open I have no noise, as I close it down to half way I get a turbulent noise, half way to closed I'm getting the whistle. It's killing the experience. I was thinking of taking a file to the vent opening and trying to slant the thin metal (it's black so not my favorite option). Any one have this issue / solution. Any opinions woi be appreciated.
Edit: Ohhhh crap rda sub not the rta sub. Please move it.
