What changed

This example pairs a stock, untuned system against the same setup after applying a parametric EQ cut at a room-mode peak near 60Hz and correcting time alignment between the subwoofer and main speakers. The result: a noticeably flatter response, lower distortion at the previous peak frequency, and tighter, less smeared bass.
