In a closed box approximately 7 ft^3, they're F3 at 40Hz, -6dB at 30Hz

Vented at 30 ft^3, they're F3 at 20Hz

Now 30ft^3 does approach difficult to accomodate in a domestic situation (to put it mildly), but would it be worth it vs. 6dB of EQ in 7 ft^3 to flatten the response to 30Hz (probably not even that much boost with room augmentation)?
