Ok i guess i can do some more research, but today i also passed by one of my local Harvey Norman's and found the Accusound Theta series whiched sounded like it exploded with deep bass and i found that the sub had a very low frequency of 19Hz and that was within my price range but my budget cannot spill over $1,800 australian dollars so i am despretaly searching for something that will impress me with my budget, I have two weeks b4 my next pay and would like to use my time wisely to find pure satisfaction... Thanks
