1 Pc 4 ohm 5 watt 3 inch Subwoofer for Home Theater for DIY Bluetooth Speaker, Electronic Projects etc

A 4-ohm 5-watt 3-inch subwoofer is a small audio speaker designed to reproduce low-frequency sounds, typically bass and sub-bass frequencies. Here’s a breakdown of its key characteristics:

• Impedance: The subwoofer has an impedance of 4 ohms. Impedance measures the opposition to the flow of electrical current in the speaker. A lower impedance value like 4 ohms means the subwoofer is easier for an amplifier to drive and can potentially produce more power.
• Power Handling: This subwoofer can handle a maximum of 5 watts of power. This power rating indicates the amount of electrical energy the speaker can handle without being damaged. In this case, it’s suitable for low-power applications.
• Speaker Size: The subwoofer has a diameter of 3 inches. This refers to the size of the speaker cone, which is the part of the speaker responsible for moving air to create sound waves. A 3-inch subwoofer is quite small and typically used in compact audio systems or applications where space is limited.
• Application: Given its relatively low power handling and small size, this subwoofer is most suitable for applications where compact size and lower bass output are acceptable. It may be used in small portable speakers, car audio systems, or other devices where space and power constraints are a concern. However, it’s important to note that a 3-inch subwoofer is not designed for producing deep, powerful bass typically associated with larger subwoofers.
