Did you know a microphone is a speaker backwards?
Years ago, a good speaker was a 3-way speaker; the bass, midtone, and treble – therefore able to cover the whole audio frequency spectrum. With technology advances, 2-way speaker can sound just as good by being able to span a broader range of frequency to alleviate the midtone, the middle speaker.
The woofer is magnetically charged with a current running through it, allowing it to subtley move back and forth. This vibration pushedsand pulls the air pressure, both in front and behind it. A vitual thing about making and designing a great, powerful speaker like this is to have an escape; a port
Additionally creating a truncated shape speaker, so that the sound waves can sporatically bounce around , allowing for an easier air pressure escape and over-all sound.
