Hi guys, I will be creating a series of short interactive episodes that you can use anywhere and anytime to provide an insight into a car audio systems performance. (Please adjust your volume) On this short, there is an approximately 30 second long frequency sweep from 20hz ~ 20khz, which covers the entire spectrum of human hearing, but not all systems are created equal and as such you may or may not hear / feel the entire range of frequencies played, on the next short I will talk about what can be done to fill in the missing audio! Thanks for listening! Do you enjoy these interactive episodes? Let me know!
