I see Shannon´s mentioned that VLC player should be fine for playing subs (and yes, my speakers can play ultrasonics)...however, I have no idea where I can see at which level the dB is "at the source". As far as I know, VLC does not display anything about "at the source". It just displays volume from 0% to 125%. I use windows8, and I can see on Speakers Properties the soundcard output/Speakers Levels that I can adjust, from 0% to 100%.
Where/how can I see and adjust the dB level "at the source"? Thanks.
At the source, means you measure from right close up to the speaker. Within an inch or so will suffice. As opposed to measuring where you are listening from. Due to the difference in those, there can be a huge difference in volume and this effectiveness.
The software needed to measure is a phone app called Frequensee. That's how you measure the volume output and calibrate it effectively.
