: A common technique is to boost one and cut the other at the same frequency (e.g., 60 Hz or 100 Hz) to prevent clashing.

Based on established standards and common tools for these frequencies, 1. Audio Production and Mixing

: Instead of a sharp cut, use a low shelf on the master bus for a more natural sound.

: This range is often "felt" rather than heard. Professional guides recommend using a high-pass filter (HPF) around 20–30 Hz to remove subsonic rumble that can interfere with compressors and limiters. EQ Strategies :

: Removing low frequencies from non-bass instruments (like guitars below 70-80 Hz) prevents "muddiness" in the overall mix. 2. Sub-GHz and Radio Communication

The "low-frequency" (LF) designation in radio refers to the range.
