Best Cheap, Small, High Sensitivity Speakers

"Does this exist or am I barking up a non existent tree?"
There is trade off in speaker performance. You must sacrifice 1)effeciency, 2)frequency response or 3)cabinet size. The laws of physics demand that you cannot have all three. This is a well settled fact. One fairly clear article on this subject is at trueaudio.com (truaudio.com/1st_trade.htm) I believe that is the correct site (in parens) according to my notes. If not, go to the trueaudio.com site and search the site for an article by John L. Murphy called "Loudspeaker Design Tradeoffs." If you want small, sensitive speaker, you cannot get a low frequency (Big bass) too. I do not care what anybody says and neither should you.
good luck
