Message: <blockquote data-quote="T3mpest" data-source="post: 4120842" data-attributes="member: 560148">cone sizd does NOT dictate how low a speaker can go.  A frequency is literally the speaker moving back and forth a given amount of times per second.  There is no reason to beleive that a small speaker can't move slowly...The only issue with smaller speakers is that to hit a given SPL at lower frequency you need to move alot of air.  After all, since the speaker is moving less times per second, it needs to either grab more air (bigger cone) or increase the distance it moves (SPL) to move create the same pressure variation as even a very small driver does, since it gets the advantage of moving 20,000/second!  (that's why tweets can be small and effecient).  Anyway to overcome the displacement issues simply use enough drivers to equal out to a bigger cone, or use a passive radiator or ported box.</blockquote>
