Fish Chris Posted September 3, 2011 Report Share Posted September 3, 2011 So I've heard that the "only" speakers that really do anything substantial, for your total SPL #'s, is the subs. Do you agree, or disagree with this ? The reason I ask, is that you can put a decible meter in a very quiet room, and lets just say it registers 40db's. Now, you crank up a little shelf system, and turn whatever small amount of bass the thing makes, completely off. Suddenly that 40 db's jumps to 95 db's, with nothing but mids and highs...... Yet mids and highs have close to zero effect on a car system with big bass ? Why is this ? Just curious, Fish Quote Link to comment Share on other sites More sharing options...
matt402 Posted September 3, 2011 Report Share Posted September 3, 2011 A weighted & C weighted decibels... bass under 100hz (C weighted) is S.P.L. Quote Link to comment Share on other sites More sharing options...

Fish Chris Posted September 3, 2011 Author Report Share Posted September 3, 2011 Okay.... So Matt, your saying that the upper frequency db's would matter / be added, "if" they were included in SPL contests (which makes more since to me) but just that SPL contests are looking specifically for loud bass ? You guys ever see those mega-loud setups from Mexico, and South of there, which have like hundreds of mids/highs, but bass often seems to be ignored ? I wonder how they meter those ? A weighted ? Or just a full spectrum sweep ? Thanks, Fish Quote Link to comment Share on other sites More sharing options...
