Speaker - 3W 4 Ohm

From the shop's description

Description Listen up! This 2.8" x 1.2" speaker is a great addition to any audio project where you need 4 ohm impedance and 3W or less of power. We particularly like this speaker as it is small and enclosed for good audio volume and quality. It has a handy JST 2PH input cable to add audio to your displays and other projects (this connector is part of the JST-PH series which is ~2.0mm spacing). This speaker will work peachy-keen with any of our mono audio amps, such as the PAM8302 or MAX98357A mono class D amplifiers Technical Details Speaker weight: 26.4g Dimensions: 30mm x 70mm x 17mm / 1.2" x 2.8" x .7" Cable is 22.5" long 3.4mm diameter mounting holes; may vary 20% in diameter 24mm x 63mm mounting hole rectangle
