So I talked to
partsexpress about the Epic 12". They recommend 0.75-1.0 cubic feet enclosure for the Epic 12"(that's including the 0.141^3 ft of the sub). The tech recommended me to go with smaller box because the cabin gain of my civic will increase the output of Epic 12". Does that sound right? I've done some research on the epic and several people recommend using bass boost to increase the output of the sub. Will that result in bad sound quality? Also, the Epic has a Qms of 7.80 which is quite high compared to other subs that I looked at. Let's say I don't like the way the Epic sounds in a sealed enclosure and decide to go ported. Will the Epic sound bad in a ported enclosure because it has a high Qms? What will be louder an Tc Sounds Epic 12" running off ~350 W or Fi X 12" running off ~350 W assuming both are in a 1.0^3 ft box?
