## Description

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. Adafruit played some David Bowie through two of these speakers using [Adafruit's MAX9744 amplifier running from 12V power](https://core-electronics.com.au/stereo-20w-class-d-audio-amplifier-max9744.html) and it could easily fill 5,000 sq ft with sound. For best use, place into some sort of enclosed cabinet.
