QK 6 Woofer

The “QK Series 6” woofer, often referred to as a 6-inch woofer, is a loudspeaker designed to reproduce low-frequency audio, typically within the 40 Hz to 500 Hz range. These speakers are often called bass speakers and are designed to handle low and low-mid frequencies.

STEG Italy, with GT-Trading, has stood for uncompromising quality and performance in the car hi-fi sector for over 30 years. Large and extremely powerful car amplifiers, as well as very small amplifiers with high efficiency, are available. Speaker systems with authentic music reproduction and high efficiency.

  • Nominal Diameter: 6 inches (15.24 cm). 
  • Frequency Range: Typically between 40 Hz and 500 Hz, but can extend to 8 kHz depending on the specific model. 
  • Power Handling: This refers to the amount of power a speaker can handle without damage, often specified as RMS (continuous) and peak power. For example, a 6″ woofer might have a 60W RMS power handling or a 100W program power. 
  • Impedance: Measured in ohms (Ω), indicating the speaker’s electrical resistance. Common impedances are 4 or 8 ohms. 
  • Sensitivity: Measured in decibels (dB), indicating how efficiently the speaker converts electrical power into sound. A higher sensitivity number means the speaker will be louder for the same amount of power. 
  • T/S Parameters (Thiele/Small parameters): These parameters describe the woofer’s behavior in different enclosures and are important for optimal enclosure design. Some key parameters include: 
    • Fs (Resonant Frequency): The natural frequency at which the speaker cone vibrates most easily. 
    • Qts (Total Q): A measure of the damping of the speaker’s vibrations. 
    • Vas (Equivalent Volume): Indicates the stiffness of the speaker’s suspension. 
    • Xmax (Maximum Excursion): The maximum distance the speaker cone can move without distortion. 
  • Magnet Material: Commonly ferrite or neodymium. 
  • Voice Coil Diameter: The size of the coil that moves within the magnetic field. 
  • Winding Material: Copper is a common material for the voice coil. 
  • Former Material: Kapton is a material used for the voice coil former. 
  • Mounting Information: Includes overall diameter, cutout diameter, and mounting depth
