The transmission distance of a column speaker mainly depends on its power and environmental conditions.
Transmission distance range
The transmission distance of a column speaker is generally between 100 meters and 300 meters. Specifically, an outdoor waterproof sound column with a power of 30W to 100W may have an effective transmission distance of about 150 meters to 250 meters in a relatively open outdoor environment. The sound transmission distance of a 40W sound column is about 200 meters.
Factors affecting the transmission distance
Power: The greater the power, the higher the sound intensity and the farther the transmission distance. For example, a single transmission distance of a 30W or higher power sound column is more than 150 meters.
Frequency: Low-frequency sound has better diffraction ability than high-frequency sound and can propagate farther in an environment with more obstacles.
Environmental factors: An open environment helps the sound propagate farther, while obstacles such as tall buildings, mountains, and trees absorb, reflect, or scatter the sound, thereby reducing the transmission distance.
Audio Quality and Volume Adjustment: High-quality audio and proper volume adjustment also help improve transmission distance and listening effect.
