Yeesh, a bit touchy there, sry mate! If I out a smilie, I am not serious!
NOtice the lack of smilies!
Anyway, the whole point of a subwoffer..I like, that, woffer, even when tracks are encoded, is exponential bass.
Yes, you are completely right, in ideals, each speaker should have a full range, but that's near impossible to buy, and only useful in STEREO!!!
Also, everything else I agree wholeheartedly with.
Speaker in the show room, aren't speakers in your living room, and as such, you really need to consider the size of the room before buying speakers. that said though, the difference in 700-1000 dollars in a budget is HUGE, sonically.
If you can bear, hold off for better savings, or brave the boxing day masses!
