Speaker driver specs explained for beginners: the 5 numbers that matter (Fs, Qts, Vas, Xmax)

A driver spec sheet looks like alphabet soup, but as a beginner you only need five numbers: Fs, Qts, Vas, Xmax and sensitivity. Here's what each one means in plain English, then I try them on two real drivers: a 6.5" mid-woofer and an 18" subwoofer.

Sealed vs ported vs passive radiator: https://nbaudio.com.au/blogs/guides/sealed... Measure your own drivers: Dayton Audio DATS V3: https://nbaudio.com.au/products/dayton-aud... Every driver figure is from the maker's own datasheet. About the voice: I made a clone of my own voice (ElevenLabs), and AI uses it to read my videos. I'm busy running a few online businesses and I'm no good at filming or editing, so AI is what gets these videos made. I write and check every script myself. 0:00 Five numbers 0:43 Fs 1:05 Qts 1:28 Vas 1:46 Xmax 2:09 Sensitivity 2:31 Two real drivers 3:39 Free box modelling 4:05 Recap
