Subwoofer Placement Calculator — Crawl Method & Corner Gain | TheaterOwl

Find the best subwoofer placement using room mode analysis and corner gain calculations.

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.

Cách thức hoạt động

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.

Kịch bản sử dụng

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

Cách sử dụng máy tính vị trí đặt loa siêu trầm

Nhập kích thước phòng để tính tần số mode trục và so sánh các phương án vị trí loa siêu trầm.

Đặt ở góc cho thêm +6 dB nhờ boundary gain. Tường trước cho +3 dB. Đặt ở giữa cho đáp ứng đồng đều nhất.

Phương pháp Crawl: đặt loa siêu trầm tại ghế nghe, phát tone bass thử rồi đi quanh phòng để tìm vị trí tốt nhất.
