As is well known, the function of the sound column is twofold: firstly, it serves as a support panel. Secondly, it plays a role in conducting sound waves (transmitting vibration waves from the panel to the back panel).

The smaller the weight of the sound column, the smaller the loss and distortion of the sound wave (vibration wave) during transmission. That's why after years of drying, the sound of the sound column is better.

Therefore, some people propose to make the sound column thinner, the more detailed it is, the lighter the weight. But a problem with making the sound column thinner is that a cross-section that is too thin can easily get stuck in the panel and backplate due to increased pressure. Moreover, the contact surface with the panel and back panel has become smaller, which can easily lead to incomplete transmission of vibration waves, known as the "filtering effect", directly causing distortion of the sound quality. Therefore, some netizens on the forum suggested making the sound column hollow, determining the length, and then sealing both ends. This idea is good, but it is quite cumbersome to operate and requires high precision in equipment and craftsmanship.

Therefore, I imagine that if we could create the shape of a power plant condenser tower like the sound column on the right in the picture, which would not only reduce the weight but also not affect the contact area between the two ends and the panel back plate, is this feasible? I hope everyone can discuss it together.
