OK, How does one make ones speaker sound 50% better, with no cost to ones self ?? And have you done so yet ? And most important, did it work ?
There's a lot of basic speaker setup ideas that most of us probably figured out on our own or learned fairly quickly but I see screwed up on a regular basis. Things like sticking a speaker against the wall, right down in a corner, not pointed at your ears, etc.
It's probably just basic setup stuff though quantifying it to specifically 50% is just marketing.
