Let's take a look a the frequency spectrum. In a recent thread that was locked by a moderator one member wrote; From those and other remarks I have read on RO, it's apparent to me that some do not have a good grasp on how low 40 or 50Hz really is. I doubt most could hear a 20 Hz tone if it kicked them in the butt unless it was 100dB! I have a large pair of Tannoy 12 coaxials that begin to roll off below 50 Hz and are down 12dB @ 40 Hz and I get a ton of bass out of them. Where does "bass" start? AT 200Hz.? 100? .... and how low do you need you monitors to go in order to be able to perform a good mix? I am interested in hearing your opinions.
