So I had some free time and wanted to see how much low frequency my iPhone X can produce with its internal speakers. To my surprise, it produced much lower frequency than my 2012 macbook pro retina(lowest produced --above 200hz), iPad Pro 12.9 first gen (140hz), jbl flip 4 (80hz)!! I dont know what kind of magic they put in to these speakers!! How in the world were they able to make this tiny speakers produce 40hz?!?! I thought laws of physics prevented tiny speakers to make deep bass. They're not strong but it still make the sound. Anyone have any idea what they did differently here with the iPhone X's speakers?
