Subwoofer's Stage Noise Cancellation and General Impressions

A perfect performance is not only a visual feast but also an auditory feast. In the stage space, the visual and auditory senses complement each other, so that the audience can fully experience the beauty of art, produce aesthetic pleasure, and gain. With the continuous development of stage control technology, professional speaker sound simulation manufacturing methods are also constantly updated. As a professional speaker and sound design operator, in art practice, he must strengthen his study, broaden his horizons, improve his business, and keep up with the development of the times.

Eliminate noise effects

Try to choose Subwoofer equipment with excellent performance and eliminate audio equipment with backward technology, to improve the service level of stage audio. At the same time, before each performance, it is necessary to conduct a test run on the audio equipment to solve the noise problem in time. Finally, some audio noise is difficult to eliminate, requiring technicians to use various techniques to enhance the clarity of the sound. And, try to avoid other electronic equipment harmonics from interfering with Subwoofer equipment. Keep the audio equipment at a certain distance from the power supply equipment and lighting equipment to improve the sound effect of the stage.

The general impression of Subwoofer

When it comes to Subwoofers, the general impression is that "bigger is better". The woofer used in the Subwoofer needs to have a large diameter, high power, and large cabinet volume so that it can output bass with sufficient energy and low frequency. Therefore, Japan's Diatone was crazy enough to make a 1600mm caliber woofer and used this behemoth to create a giant subwoofer, the D-160, which achieved an amazing low-frequency response range of 8Hz to 500Hz. This also allows us to fully realize the importance of large-diameter woofers for reproducing low frequencies. But it is very difficult to make such a subwoofer, even if it is made, it is difficult to apply it to the home environment. Just like the Diatone D-160 just mentioned, it is very heavy and very large, and it can only be used for research in the end.

At present, the most commonly used specifications of large-diameter woofers used in Subwoofer are 15 inches and 18 inches, and the larger ones are 21 inches or even 24 inches. Although they are much smaller than Diatone's 1600mm diameter woofer, they are still huge in a home environment. In other words, if you want to play a large-caliber subwoofer, you must have enough space in your home to place it.
