Definition:
The middle of the bass part of the frequency range, from approximately 50 to 100 Hz (upper bass would be from 100 to 200 Hz). Also used as a term for loudspeaker drivers designed to reproduce both bass and midrange frequencies.

Reality:
Midbass is often overlooked in a custom car audio setup and replaced by large numbers of speakers to try and fill the gap between highs and lows.

Lots of companies have produced mid-bass speakers but they are often overlooked for a component sets instead.

Why do I need it?
You need mid-bass speakers because they bridge the frequency response allowing for a fuller, cleaner sound. They also allow for you to use lower wattage subwoofers as you are able to create upfront bass similar to what you would experience at a live concert. Bottom line is that the addition of midbass to a system can bring it that much closer to live performance in your vehicle.
