Subwoofer, woofer, and tweeter are all terms used to refer to different types of drivers in a speaker system that handle different frequency ranges. Here are the technical specifications and units of measurement commonly associated with these drivers:


Subwoofer:

  • The subwoofer is responsible for producing low-frequency sounds, typically below 200 Hz.
  • Some of the key technical specifications associated with a subwoofer include:
  • Frequency response: It indicates the range of frequencies the subwoofer can reproduce. It is usually measured in Hertz (Hz) and represented as a range (e.g., 20 Hz - 200 Hz).
  • Power handling: It denotes the maximum power the subwoofer can handle without distortion. It is measured in Watts (W).
  • Sensitivity: It refers to the subwoofer's efficiency in converting power into sound. It is measured in decibels (dB) and provides an indication of how loud the subwoofer will be with a given amount of power.
  • Impedance: It represents the electrical resistance offered by the subwoofer to the amplifier. It is measured in Ohms (Ω) and impacts the power transfer between the amplifier and subwoofer.

Woofer:

  • The woofer handles mid-frequency sounds, roughly ranging from 200 Hz to 2 kHz.
  • Some of the key technical specifications associated with a woofer include:
  • Frequency response: It indicates the range of frequencies the woofer can reproduce. It is typically measured in Hertz (Hz) and represented as a range (e.g., 100 Hz - 10 kHz).
  • Power handling: It denotes the maximum power the woofer can handle without distortion. It is measured in Watts (W).
  • Sensitivity: It refers to the woofer's efficiency in converting power into sound. It is measured in decibels (dB).
  • Impedance: It represents the electrical resistance offered by the woofer to the amplifier. It is measured in Ohms (Ω).

Tweeter:

  • The tweeter is responsible for producing high-frequency sounds, typically ranging from 2 kHz to 20 kHz or higher.
  • Some of the key technical specifications associated with a tweeter include:
  • Frequency response: It indicates the range of frequencies the tweeter can reproduce. It is typically measured in Hertz (Hz) and represented as a range (e.g., 2 kHz - 25 kHz).
  • Power handling: It denotes the maximum power the tweeter can handle without distortion. It is measured in Watts (W).
  • Sensitivity: It refers to the tweeter's efficiency in converting power into sound. It is measured in decibels (dB).
  • Impedance: It represents the electrical resistance offered by the tweeter to the amplifier. It is measured in Ohms (Ω).


It's important to note that these technical specifications may vary depending on the specific model and manufacturer of the speaker components. Additionally, there may be other specifications or measurements that are relevant to consider, such as crossover frequency, distortion levels, and physical size.
