Many professionals in the professional audio industry are technical personnel who have been immersed in it for many years, and their pursuit of "good audio" and "good sound" can be said to be their lifelong goal. But what is a good sound system? For this question, even professionals have multiple different understandings and answers. Below, we will discuss the standards and characteristics of a good audio system from the following aspects for your reference.
1、 What is a good speaker
From a scientific and objective perspective, a good speaker is one that has a wide frequency response, high sensitivity, high power, balanced curves, and accurate phase. A good sound system is one that combines speakers with amplifiers, maintains consistent phase and balanced natural frequency response curves after the front and rear stages, and provides a clear, soft, and realistic listening experience during music playback.
A speaker with a wide frequency response has strong expressive power, high sensitivity makes it easy to make noise, high power makes it relatively stable and safe, balanced curves, and reasonable and appropriate phase connections will not cause distortion due to energy consumption, thus allowing for the true and natural reproduction of various sounds. The sound has a strong sense of hierarchy, good separation, brightness, clarity, and softness. A speaker with high sensitivity and high power is not only easy to make noise, but more importantly, its maximum sound pressure level within a stable and safe range can "overpower the crowd", and the required sound pressure level can be obtained without too much power drive.
In terms of subjective evaluation, due to differences in personality, cultural cultivation, artistic cognition, preferences, and standards, people have different opinions and ways of description.
Our comprehensive subjective evaluation is that a good speaker is one that can "shock loudly, but is bright and clear without being harsh, has a smooth listening experience, is authentic and natural, and has good elasticity".
As a private room speaker, it is also necessary to add the requirements of "easy to sing, durable (able to Hi), and strong surround feeling".
2、 What is a good amplifier
The standard for a good power amplifier is reasonable efficiency, appropriate damping coefficient, wide frequency response, strong voltage transformation ability, normal and balanced output waveform, high signal-to-noise ratio, low distortion, and strong analytical power. When such an amplifier is paired with a balanced high-quality speaker, the sound it produces appears clean, clear, well separated, and has a distinct listening experience.
What exactly is a good sound system
Of course, power amplifiers, like the voice coil of speakers, generate high temperatures during operation, so they must have a reasonable circuit, high-quality components, and good heat dissipation devices.
A high-quality amplifier is one that meets the above conditions and can produce soft, clear, and "transparent" sound quality in conjunction with a speaker, and can work stably.
3、 What is a good front-end
The most important indicators of a good front-end are that the reverberation chip, operational amplifier, and circuit are all good, with appropriate, reasonable, sufficient functions, strong adjustability, and realistic and natural sound.
4、 What is a good microphone
A good microphone is one that, when paired with speakers, amplifiers, and front-end speakers, produces authentic and natural sound (with all the necessary sounds). If it is wireless, a U-shaped wireless microphone that does not run frequency, does not run frequency, is resistant to drops, shocks, and is durable is better.
A sound system that can meet the above subjective and objective conditions is a good sound system. Don't blindly believe in "American", "Japanese", or "British" - whether the sound system is good or not, the comparison is actually very simple: while listening to familiar songs, pick up the microphone and hum a few lines, switch back and forth for comparison.
Of course, if you have professional knowledge and testing equipment, in addition to subjective comparison of listening and singing effects, objective and scientific testing comparison is also one of the good methods. At any time, people's subjective consciousness may inevitably mislead themselves, but objective scientific data will not "deceive" them.
