Looking for a sub under the £300 mark. I was looking at the bk gemini, the mj acoustics pro 50 mk2 or the bk xls200 but prefer the size of the first 2 subs. I have a q acoustics 1000i but this is a terrible sub and the port makes nasty sounds everytime the bass kicks in, would this be solved by going for a non ported box and do they still sound as good?
