Small subwoofer theory

Can you build a small subwoofer with a physical presence Sound Pressure Level (SPL)?


I have received several questions from my channel subscribers and listeners.


The core question was can I get 20Hz at -3db from a small size subwoofer and how much power do I need?


In this video, I covered subwoofer and SPL basics and included basic theory to answer this question.
