Is it worth getting a cheap sub? Simple as that. I am basically very happy with my system on most music but there are times when I could do with more bottom end (my speakers are -6bd @ 40htz). Like last night for example, I was listening to "Dub plates from the elephant house" and on a track I know has deep bass lines it was all a bit too light, the bass is there but its simply too quiet. So to that end I was considering an MJ acoustics or REL sub for around 300-400 as a possible solution. Is if fair to say that at that level I'm going to have rotten boomy crap or will I be able to buy a decent bit of bass? Obviously I'll buy S/H.
