Fi Q 15 high QTS questions

[Jhunt94]

I had a question about my Fi Q 15 and I figured that this would be the perfect place to ask questions related to car audio so I made an account and here I am. I bought a Q 15 with the high QTS option because I have a regular cab F-150 and I intended to run the subwoofer sealed because I couldn't make a very big box without taking out some of the interior. Well after playing around with measurements of the box I built a box that is 3.3 cu ft and is within the numbers recommended by Fi to run the subwoofer ported. Right now the box is sealed but I've thought about putting a port in it. My question is would it sound fine if I decided to port the box or should I keep the box sealed. I saw where someone said that Fi told them it would be alright to but the high QTS sub in a ported, but I don't know if the person really talked to someone from Fi. I'm hoping someone here can help me.

High QTS is for sealed not ported. If you want to port something, do a 4th order not a ported box

Besides... 3.3cuft before port displacement, not enough space to run a port anyway. You'd be close to 2-2.5 cuft once your factor in the port. Wayyyyy too small for a 15"

Oh I forgot to mention that measurement was done on a calculator and it was 3.3 after displacement
