Electronics Crafts 3 Inch Woofer Speaker 4 ohm 25 Watt Pair (2 pieces) 3 Inch Speaker (Pack of 2) car speaker MAX power Coaxial Car Speaker  (20 W)

Diameter: 8 cm (or approximately 3.15 inches) Impedance: 4 ohms Power handling: 25 watts Rated output power: 20 watts Sound pressure level (SPL): 67 dB It's important to note that the diameter of the speaker is given as 8 cm, which is slightly smaller than 3 inches. However, the difference is relatively small and shouldn't have a significant impact on the overall performance. The impedance of the speaker is 4 ohms, which represents the resistance to the flow of electrical current. This value is important to ensure proper matching with the amplifier or audio source. The power handling of the speaker is 25 watts, indicating the maximum amount of power it can handle without getting damaged. It's important to avoid exceeding this limit to prevent potential damage to the speaker. The rated output power is 20 watts, which suggests the recommended power level at which the speaker can operate efficiently and produce the intended sound output.
