The 2 Inch 52mm 4 Ohm 3W Speaker for DIY Bluetooth Speakers is a high-performance full-range micro loudspeaker engineered specifically for custom portable audio, Bluetooth speakers, and DIY sound… 2-Inch (52mm) outer frame diameter · 2Inch.
The 2 Inch 52mm 4 Ohm 3W Speaker for DIY Bluetooth Speakers is a high-performance full-range micro loudspeaker engineered specifically for custom portable audio, Bluetooth speakers, and DIY sound projects. Built with a flexible rubber edge surround and a high-rigidity composite cone, this speaker delivers impressive low-frequency bass extension and crisp high-frequency clarity despite its compact size.
Operating at a 4Ω impedance with 3.0W rated power (5.0W maximum peak), it draws optimal power from low-voltage Class-D amplifier boards operating on single-cell LiPo batteries (3.7V - 5V). Its high-density magnetic structure ensures efficient acoustic output and minimal sound distortion at higher volume levels.
Featuring a standard 52mm outer diameter (2 inches) with four corner mounting holes, this speaker is easy to install inside 3D-printed enclosures, wooden speaker boxes, or plastic cabinets. It interfaces seamlessly with popular Class-D audio amplifier modules (such as PAM8403, PAM8406, or TPA3116D2) and microcontrollers like ESP32, Arduino, and Raspberry Pi.
