[QUOTE="Ivan Beaver, post: 75547, member: 30"] Re: When LARGE dinosaurs roamed the earth... Well at the open demo yesterday-we were playing around with some subs at one point. On some songs, when the bass went down low-the notes simply weren't there. And this was with a very popular 2x18" concert sub. When we switched to a subs with smaller diameter woofers (and had a much lower freq response), you could hear all the notes the artist put in the recording. They did not play those notes so that the speaker system could not reproduce them-they INTENDED for them to be heard. There are only a few high output subs that have a REAL (as referenced from rated sensitivity) -3dB point below 30Hz. Forget the "simple specs" look at the measured response-WITHOUT adding low freq boost-any sub can go lower if you do that-but it takes away from the max loudness (manufacturers "forget" to mention that BTW). But when you hear a sub that goes below 30Hz solid-you QUICKLY realize how important it is to be able to do so-at least with some forms of music. With other styles of music-it is not a big deal.
