Closed or bass reflex?
The SPH-380TC does not sound much lower in a well-tuned bass reflex setup than in a closed design (with proper equalization), but may sound less precise.
The lack of draft in a closed design is compensated by an equalization (+ 5dB @ 32Hz) in the lowest frequency range by the active module. The downside of this is an increased power requirement.
In terms of depth, the two variants do little to nothing. The closed version may play (still) a bit more precise, the bass reflex version is less power hungry and even better.
Build the subwoofer in BR and make the tubes lockable! This way, all options remain open at all times.
Due to some inquiries:
The subwoofer definitely makes "wind" in home cinema, even in a closed design. 30 Hertz are easily reached and 15 inches with + -11mm linear hub are just a "house number" 😉
So that the subwoofer should be operated exclusively closed, the volume can easily be reduced to up to ~ 50Liter. The result would be a slightly lower draft (~ 2 dB less level at 30Hz).
