The technical parameters of the speaker cabinet mainly include the following aspects:
Frequency response range: The frequency response range of the speaker, usually expressed as the lowest frequency and the highest frequency. For example, the frequency response range of the British Bowers & Wilkins 805 D4 bookshelf speaker is 34Hz~35kHz.
Frequency response: This is the output change of the speaker within a specific frequency range, usually expressed as a bandwidth of ±3dB.
Sensitivity: The sensitivity of the speaker refers to the sound pressure level produced under unit power input within its frequency response range.
Harmonic distortion: This is the distortion of the speaker at a specific sound pressure level, usually expressed as a percentage.
Impedance: The impedance of the speaker is one of its electrical characteristics, usually in ohms.
Recommended amplifier output power: This is the recommended amplifier power range to ensure that the speaker can work properly and without distortion.
Size and weight: These parameters directly affect the physical installation and space requirements of the speaker.
These parameters together determine the performance and applicable scenarios of the speaker. For example, a high-sensitivity speaker can produce a higher sound pressure level at the same power, which is suitable for occasions that require high sound pressure; while a low-distortion speaker is suitable for applications that require high-fidelity sound effects. In addition, impedance and power matching are also key factors to ensure the stable operation of the speaker.
