Listen up! This high power 4" diameter speaker will amp up any audio project where you need loud sound! It is 4 ohm impedance, rated for 20W continuous power. (This thing is really loud) It also has four handy mounting tabs 3 inches apart, and a grill that fits on top. The grill is to protect the cones, and is not necessary for use.
This speaker has a nice wide range of 60Hz - 24kHz, which is pretty good for a speaker this large. Originally designed for use in car doors, but we think its good for any project where you need to fill a room. We played some David Bowie through two of these speakers using our MAX9744 amplifier running from 12V power and it could easily fill 5,000 sq ft with sound. For best use, place into some sort of enclosed cabinet.
