You don’t need to attack people in order to teach them something. It seems like there’s other things going on in your life that are bothering you. I hope things get better for you soon man.

Why so hostile?

Why wouldn’t you buy a sub from a speaker company? Here’s one for audiophiles: if you want real good sound look at studio equipment rather than expensive hifi stuff. A high end studio interface plus a pair of full range studio monitors will sound more accurate than any hifi setup.

And another one: listening experience is 95% acoustics. Don’t bother with speakers above say 2k if you’re not willing to invest money and space into proper acoustic treatment.
