problem
Width is powerful when it supports the center. It becomes risky when it hides phase problems or weakens the low end.
A mix can sound impressive in headphones and then lose guitars, synths, or reverbs on a mono speaker. That usually means important information was living too heavily in the sides.
Stereo width should create space around the song, not carry elements that disappear when playback changes.
Haas delays, chorus, stereo enhancers, and unaligned doubles can all increase width. They can also reduce correlation and make mono playback less predictable.
The lower the frequency, the more carefully width should be checked. Wide sub energy can make the entire mix foundation unstable.
Use correlation, mid-side balance, and mono checks while widening. If the mix only works in stereo, narrow the source, adjust timing, or move width to a safer frequency range.
