What are the main differences between full-range active speaker amplifiers and passive speaker amplifiers?

1. Built-in amplifier or not
Full-range powered active speaker amplifier: It has a built-in power amplifier that can directly receive and amplify the audio signal and then drive the speaker to make sound. This design simplifies system connections, reduces dependence on external devices, and generally provides better sound quality and power output.
Passive speaker amplifier: There is no built-in power amplifier, and an external power amplifier is required to provide the required audio signal amplification. This design is relatively more traditional and requires more external equipment support.

2. Performance and function
Full-range powered active speaker amplifier: It usually has higher power output and better sound quality performance. In addition, some high-end models also have a variety of audio processing functions, such as DSP (digital signal processing) technology, which is used to optimize sound quality and provide additional audio effects.
Passive speaker amplifier: Although the performance may be slightly inferior to that of active speaker amplifiers, in some specific applications, such as when a highly customized audio system is required, passive speaker amplifiers may be more flexible.

3. Product parameter comparison
Power supply type: The full-range powered active speaker amplifier adopts LLC high-efficiency resonant power supply, which is usually designed with higher efficiency and lower power consumption. Passive speaker amplifiers rely on external power supply.
Output power: The full-range powered active speaker amplifier has clear output power parameters, such as 500W/4Ω for low frequency and 200W/8Ω for high frequency, which indicates that it can provide enough power to drive the speaker to sound and meet the audio needs in different frequency ranges. The output power of the passive speaker amplifier depends on the connected external power amplifier.
Operating voltage range: The full-range powered active speaker amplifier has a wide operating voltage range, such as 220-240 volts AC and 100-120 volts AC, which enables it to adapt to the voltage standards of different countries and regions. The operating voltage of the passive speaker amplifier depends on the connected external power amplifier.

4. Application scenarios
Full-range powered active speaker amplifier: Due to its built-in amplifier and sound quality performance, it is often used in occasions requiring high-quality sound effects, such as concerts, theaters, recording studios, etc.
Passive speaker amplifier: It is more suitable for audio systems that require high customization and flexible configuration, such as home theaters, professional recording studios, etc.
