How many diameters are there in audio speakers?
The diameters of audio speakers currently on the market mainly include the following:
1. 3-inch speaker: The diameter is about 75~76mm, generally used as a tweeter. Hearing frequency is above 2kHz.
2. 4-inch speaker: The diameter is about 102mm, the frequency range is between 2~5kHz, and it can be used as a mid-range and tweeter speaker.
3. 5-inch speaker: The diameter is about 127mm, which has become the standard configuration of many speakers now. The main frequency is between 200Hz~2kHz.
4. 8-inch speaker: The diameter is about 203mm, used as a subwoofer. Frequencies below 200Hz can output richer bass effects.
5. 10-inch speaker: The diameter is about 254mm, which is the most common subwoofer specification. It can reach a minimum of below 40Hz, producing powerful bass shock.
6. 12-inch speaker: with a diameter of approximately 320mm, it serves as a powerful bass source for professional audio and speakers. The lowest frequency can reach 20Hz, which can fully reproduce the live roaring effect.
7. 15-inch speaker: The diameter is about 381mm, and the lowest hearing frequency can reach below 10Hz. Suitable for professional office-level speakers and cinema speakers.
8. 18-inch speakers and above: The diameter is above 400mm, generally used in theater systems and party speakers where sufficient volume needs to be generated. Sound quality requirements are not high.
Generally speaking, the larger the diameter of the speaker, the more powerful the low-frequency energy output it can produce. But high-frequency performance usually drops. The diameter of common home speakers is generally between 2 inches and 10 inches. An 8-inch or 10-inch woofer paired with a 3-inch or 4-inch tweeter is a basic configuration solution. Extremely large-diameter 18-inch+ speakers are used in a few professional audio fields.
