- A trim level is an important tool in the functioning of a subwoofer within a home theater sound system.
- While the subwoofer produces bass, other speakers in a sound system produce high-frequency crisp/sharp sound.
- The trim level moderates the low-frequency bass sound to prevent it from overpowering/draining sound from the other speakers.
- Trim level is a control separate from the volume control for the subwoofer.
- The conventional practice is to keep trim levels below zero decibels (0db), then boost bass frequency using the subwoofer master volume control.
- Correct trim level cleans out the bass and clearly distinguishes it from the rest of the sound.
- This prevents distortion of sound, projecting it as intended, and giving the best overall sound in the room.
