Ideal Compensation via Room Gain Pressure-Cavity Effect: In real-world small-to-medium rooms, when sound wavelength exceeds room dimensions, the room creates a natural pressure-cavity effect, providing roll-off compensation of approximately +6 dB/octave for low frequencies below 40 Hz. Energy that your sealed enclosure would theoretically lose is fully recovered by natural room gain and boundary effects (such as an additional +3 to +6 dB from wall or floor placement). As a result, the in-room frequency response at 30 Hz is effectively flattened into a linear curve.
