cons - china made HT in a box or even european, japan made (heck, may japan made pa ba?) will produce decent sounding audio up to a certain level only. above this, distortion would set in.

pros - as long as your ears and wallet is happy
you don't need to spend bigtime on expensive setups.

if you have a so-so sub woofer, get yourself a bass shaker like the AURA bass shakers.
