Midrange Driver
Midrange (MF): It is distinguished by the diameter of the cone paper of the midrange driver.
Common sizes include:
5 inches (inch), with voice coils typically ranging from 25mm to 38mm.
6.5 inches (inch), with voice coils typically ranging from 38mm to 50mm.
8 inches (inch), with voice coils typically ranging from 38mm to 65mm.
10 inches (inch), with voice coils typically ranging from 50mm to 65mm.

The midrange speaker driver is an audio unit in speaker systems used to produce mid-frequency sound. Midrange drivers typically use larger diaphragms to vibrate and produce mid-frequency sound waves. These diaphragms are usually made of materials such as pulp, plastic, or other composite materials.
The characteristics of midrange drivers include a wide frequency response range, typically producing a range of about 200 Hz to 2 kHz. They can also produce relatively high volume and have a degree of tonal balance, not emphasizing any particular frequency in the audio frequency range.
When selecting a midrange driver, various parameters need to be considered, including the driver's size, materials, design, sensitivity, rated power, and impedance. Different midrange drivers can produce different sound effects and have different tonal characteristics.
In summary, midrange drivers are an important component in speaker systems, producing high-quality mid-frequency sound. Choosing the appropriate midrange driver can provide better audio performance and a more excellent listening experience for speaker systems.
