Production of Multimedia Subwoofer Active Speaker
At present, due to the advent of high-speed computer CD-ROM drives, we are able to make a wide selection of wonderful multimedia software. At the same time, video games, interactive audio, and music broadcasting programs have raised higher and higher requirements for sound effects. Therefore, the high-performance sound system specially designed for the computer will be quickly promoted and applied. Unfortunately, the already expensive computer-dedicated speakers still can't reproduce deep and deep bass, nor can they produce enough volume, so when listening to music "CD" and computer games, there is no immersive feeling. Although some manufacturers of computer-specific speakers have provided small subwoofers, it is still difficult to find subwoofers with good sound quality unless you go back and buy a set of speakers and matching software packages. The most annoying thing is that high-quality subwoofers are very expensive. The multimedia subwoofer active speakers introduced here can provide your computer with deep and deep bass, but the production cost is very low. The characteristic of this device is that it contains an active bandpass overlapping filter of 12DB per octave, a 20W power amplifier and a 6-inch speaker. Two 3.5MM headphone jacks can connect this device with any sound card and multimedia speakers. When this device is installed in a multimedia speaker, its volume for satellite speakers is controlled by the volume adjustment on the subwoofer active speaker, and the total volume of all speakers is controlled by the volume adjustment on the multimedia speaker. This allows the subwoofer to be hidden under a computer desk and can be remote-controlled.
