The ambiguous launches in "Into the Forest" are partially explainable with tubes close to the nacelles. The first shots they get off when starting their dance around the Ship of the Dead emerge from the centerline, though. A bit down and aft from the deflector, but we might accept them as coming from the barrels if we really wanted.
The launches in "Sound of Thunder" won't fit the barrel model, though, so we'd have to go for at least three firing locations in the end. It's fortunate we have seen such a low number of launches in general, and that the phaser beams do emerge from the supposed emitters (perhaps those glow red for the very purpose of helping out the VFX team?).
If we accept tubes close to nacelles, we have to accept some sort of a hatch arrangement, which can then account for the centerline launchers of "Into the Forest", too. And be in sync with presumed TOS hatches. We then have to wonder why the launchers in the middle of the dish wouldn't be similarly covered, though.
