Active speaker horn
Active horn loudspeaker (Active Speaker) means that the speaker has a built-in sound divider and amplifier circuit. It only needs to connect the power supply and input the music signal to make a sound. Many studio speakers and professional speakers for engineering are active speakers, but don't think Active Speaker is synonymous with your professional, because common and commonly used computer speakers, Bluetooth speakers, etc. are actually active speakers. trumpet.
Advantage 1: No need for power stage, simple system
One of the significant advantages of active speaker speakers is that there is no need to connect the rear-level driver, and the audio can be input to play songs. For those who want a simpler audio system, only the player and the speaker can form a complete system.
Advantage 2: save space
In addition, the active speaker speakers do not need to be connected to an amplifier, so it can save a lot of space for placing equipment. It is quite suitable for the CAS system or desktop audio system that has been very popular in recent years.
Advantage 3: Complete package, guaranteed sound quality
Since the speaker itself already has a complete drive circuit and is equipped with decoding and sound division, and if it is input through a digital interface, the sound bottom of the active speaker speaker will be more stable, unlike the passive speaker speaker, which is more affected by wires and amplifiers.
Disadvantage 1: The speaker needs to adjust the volume independently
In the design of some active speaker speakers, the output of the left and right channel speakers needs to be adjusted independently, so it will be a little troublesome to adjust the volume, and the left and right speakers must be matched and then fine-tuned.
Disadvantage 2: Need to connect power cord and signal line
Although the active speaker speaker has one less Amp, in addition to the signal line, it is necessary to connect an additional power line to each speaker for power supply. If the speakers are placed farther away, it will be more troublesome to connect the line.
Passive speaker speakers
The more common two-channel speakers are passive speakers. Contrary to active speakers, there is no built-in amplifier circuit, and it needs to rely on the output of the rear stage or the combined machine to drive the sound. Compared with traditional active speaker speakers, most of them are bookshelf-type design, passive speaker speakers come in a variety of styles, such as floor, bookshelf, satellite and so on.
Benefit 1: More tuning flexibility
Due to the need to connect the amplifier driver, the sound bottom of the passive speaker speaker will be greatly affected by the connected equipment and the same wire, and sometimes the same set of speakers will appear. . However, in disguise, there is more flexibility in sound tuning. You can use the characteristics of signal lines and amplifiers to complement or enhance the performance of speakers.
Advantage 2: Only need to connect the speaker cable
Although it is necessary to connect an amplifier, on the other hand, passive speaker speakers do not need to connect an additional power cable. They only need to connect the signal cable to the amplifier, and the latter can be directly driven to produce sound.
Advantage 3: Diversified connection combination of Bi-Amp and Bi-Wire
Some passive speaker speakers can support the connection of Bi-Amp and Bi-Wire, and improve the performance of the speaker through wire connection, additional power stage, etc.
Disadvantage: need to push back
Since the passive speaker speakers are so diverse, the specifications, designs and materials are different. If we want to talk about a common disadvantage, it is the need to connect the amplifier driver, which requires additional equipment and space.
