Goodbye, JBL BOOMBOX 4

After the firmware updates to versions 26.16.10 and 26.32.10, the JBL BOOMBOX 4 can no longer reproduce the 37 Hz frequency range—the very range that delivered that signature subwoofer-like sound; now, the audio starts at 67 Hz. This was a decision made by JBL, yet that powerful 37 Hz sub-bass was the one thing we loved about the JBL BOOMBOX 4. Goodbye, JBL BOOMBOX 4.
