低音炮摆位计算器 — Crawl 法 & 角落增益 | TheaterOwl

Calculating Subwoofer Placement is a fundamental and crucial step in home theater design. It is not just about measuring distance; it must be designed based on scientific evidence to maximize human visual perception limits and immersion. Incorrect settings can cause eye strain or fail to take advantage of resolution benefits. This tool complies with industry standards such as THX and SMPTE guides to provide the most precise data.

工作原理

This system utilizes complex trigonometry and optical formulas. Based on the input variables (screen size, resolution, viewing angle, etc.), it simultaneously calculates the minimum distance where pixels do not appear clustered and the maximum immersion distance that fills the entire field of view. All results are reflected in real-time, suggesting figures optimized for the user's environment.

应用场景

• When simulating the installation space before purchasing new Subwoofer Placement equipment
• When wanting to optimize the performance of an existing home theater system and achieve professional-level tuning
• When needing to find a compromise for the best audiovisual experience within space constraints

如何使用低音炮摆位计算器

输入房间尺寸，即可计算轴向房间模态频率并比较不同的低音炮摆位方案。

墙角摆放可获得 +6 dB 边界增益。前墙位置可获得 +3 dB。中央位置则提供最均匀的响应。

低音炮爬行法：将低音炮放在听音座位上，播放低频测试音，然后在房间内走动以找到最佳位置。
