Acoustic Law (Iron Law of Audio): Small speaker enclosures must sacrifice bass extension ($f_c$), sensitivity, or battery efficiency. Stepping from the tiny portable model up to the bigger sibling cabinet grants deeper sub-60Hz punch.

Acoustic Design Insight: By expanding internal air volume to 2.4L and matching a 3.25" high-excursion cone, Helmholtz cavity resonance is relieved without requiring harsh active DSP bass shelving.
Power consumption at current target: 1.95 W average draw.
