I don't abuse on forums and i don't know why my comments are deleted.
This is a technical forum, there is no term as "heavy" sub or amp in the world of ICE.
If someone is new to this ICE world than he should not embarrass neither he should call someone a Idiot. I am just saying have a positive attitude towards members if you are seeking genuine help.
Coming back to your question, the sub woofers are of many kinds and mainly categorized by their power handling capabilities and genre.i.e. sq, spl etc.
