If you don't want boom boom sounds, don't buy anything that is for
home cinema. If you have the room, build it yourself, using a large
closed box. That will give you smoother bass than most ported boxes
you can buy. Otherwise, if you want something musical, rather than
loud and boomy, expect to spend four times that amount.

I don't know how to build such things myself - I believe I need to buy
something.
Is buying a cheaper subwoofer (around 300euro) not worth at all for
music?
