1. The reason for adding bass is:
Many small speakers with good sounds are designed with a bass auxiliary speaker. This is the only way to perfectly express the sound. Correctly designing the bass auxiliary speaker can greatly improve the sound quality of the small sound system. For large systems, The effect is not very clear, but it is certain that if the system itself is very good, it is meaningless to design and configure the bass auxiliary speaker. This will destroy the original effect of the system.
The bass is much stronger than the treble. Many people say that the bass horn can be used with one. This is just a part of it. It is not exactly the case. A few people think that 2 bass horns should be used. There are three main reasons for them:
(1). The bass frequency is not directional, and the stereo effect is correctly reflected. Two bass auxiliary speakers must be used.
(2). Using 2 bass auxiliary speakers, it is unlikely to cause standing waves in the room, and the position of the box is not high.
(3). Using 2 woofers is definitely better than 1 woofer.
The subwoofer frequency of the bass woofer is non-directional, but because the woofer is pronounced near 100 Hz, it is better to use the two bass woofers for performance stereo, which is better than one. Of course, the distance between the two woofer horns is the smallest. The value is 2 feet.
A better bass woofer, a reasonable addition to the sound system, can produce very good results, but adding 2 woofer may produce better results.
2. How does the bass woofer connect to the stereo system?
Most bass woofer speakers have amplifiers and crossovers. At this time, the bass signal output from the preamplifier can be input to the bass amp. In other cases, if the system only has the main channel output, then only the main channel is available. And a set of output dedicated to the bass power amplifier (frequency divider).
3. The necessary factors to reflect the surround sound effect
There are many products that show the surround effect, and the surround function of many amplifiers for the public is not satisfactory.
Generally speaking, in addition to the two main speakers, the surround system requires at least two rear surrounds. Advanced professional logic signal processing systems such as Lexicon and Fosgate use more rear speakers. In most cases, The main speaker is placed in the center position, 2 on the front of the surround speaker, 2 on the rear, and 2 on the side.
