What technical parameters should be paid attention to when purchasing speakers?
Need to pay attention to the following five parameters!
Rated power: The rated power of the speaker can only be determined by 75% of the rated power of the power amplifier to ensure power matching and device safety.
Rated impedance: The rated impedance of the speaker must not be less than the rated load impedance of the amplifier. Common rated impedances are 4 ohms, 6 ohms, 8 ohms, 16 ohms, etc. Transistors, integrated circuit power amplifiers generally do not use output transformers, the load impedance is 4-6 ohms, so it is better to choose 8 ohm speakers.
Effective range: Choose a speaker with a wide and flat frequency range in the range of 30 dB. Above 90 decibels to meet the needs of home audio.
Number of crossovers: The three-way speaker adds a mid-range speaker unit to the two-way speaker, making the midrange more powerful, and the speaker can withstand more power and output a larger volume.
The diameter of the speaker: the diameter of the woofer, not the bigger the better, because the larger the diameter, the more easily the paper cone vibrates when it is vibrated, resulting in split vibration and distortion.
