Yer da watches ITV through built-in speakers at 90% volume and is still straining to hear it.
TV on 14" portable CRT through proper speakers is a million times preferable experience to tinny built-in speakers on even the lushest of screens.
No need for anything fancy expensive. See above, about my 90s JVC mini system boxes still loyally serving. I’m no audiophile.
It’s about the physical volume required to create the full range of soundwaves.
Means you can have the volume down low, but it’ll still be clear enough to hear everything properly.
(Can’t be doing with try-hard overly-boomy home cinema efforts, either - they seem to go too far the other way by creating a soup of disparate sounds, or maybe I’ve only heard bad examples?)
