Hey man sorry for the change of topic in your thread but I need to ask.
I am thinking of getting a TD100 or TD100X, and I'm wondering about how stealthy you can get to be using either one. Since you are into stealth and you have both, you should know how well they fit the application.
I intend to put one of those DIY pencil-cup filters on either one of those fans, and I will not be using much ducting since it is for a stealth cab.
If you can give me some feedback on their behaviour, under similar circumstances it would be great.
BTW I think a 4" tube for a 400w bulb might be a little tight for the heat to be evacuated. continue to use the 6" if your with your 400w
