How to judge the quality of a home theater system?

Answer:

3. weight, speaker net weight. Generally speaking, the sound box is more heavy, the quality is better. Because the heavier speakers indicate that the bigger the magnet or the thicker the speakers are, the better they are.
4. synthesis, in theory, the human ear can hear the frequency of less than 20Hz~20KHz sound. All kinds of sounds in nature actually is not a single frequency sound, a "tremolo but a fundamental frequency with a variety of several times the basic frequency of the sound". The performance of sound frequency is pitch. Such as the woman's voice than the sound frequency of men's high, the tip is fine or sound we usually said, and various animal nature shouts and the sound of wind and rain, thunder, all kinds of automobiles and aircraft artificial noises are not single frequency sound, but the sound frequency range are basically in 15Hz~20KHz within. Therefore, the speakers in the restoration of these voices, it is necessary to all kinds of sound basic frequency and harmonic frequency are faithfully reflected, otherwise the sound is not real and unnatural. For example, if we see on the screen a gallop in the mountains of stone on the road, then the speaker playback hoofs like a horse hoof is wrapped up, it means the speakers and the high frequency reproduction ability is not enough; if you see playing drums on the screen, and you hear the sound was like in play the bass drum, then the reduction ability is not enough. So when we buy a speaker, we can use a CD or VCD CD to put a song or movie plot that you are familiar with. If it sounds normal, there's no sense of turbidity or acerbity, even if it's ok.

1. appearance, select speakers generally start from the shape. A multimedia active speakers, if the shape of smooth, smooth, delicate and uniform color, first of all, will give a feeling of heartbeat. Carefully check the sound box of the junction is uniform and closely based, modeling, the adjusting knob and a function key and each jack position is reasonable distribution (Note: if you want to configure the subwoofer, speakers must provide a subwoofer plug signal expansion port). In any case, you can not let go of any nuance in the observation, including the speakers on the mark or pattern, etc., exquisite, correct, clear, that the speakers of excellent workmanship, quality first class.
2. output power. If a pair of speakers is selected from the process and shape, you can pick it up to see how heavy it is. The purpose is to estimate the maximum output power of the speaker. Generally speaking, the speaker of the undistorted power should have at least 20W20W, namely each channel 20W.
