"Point Source Speakers are Better....FACT....Back to Top
The next time you see a duck (sat on a pond) take two or three pieces of bread and throw them in the pond so that they land close together and at the same time. Watch the ripples produced and how they spead out - you will see they are very confused - hard to follow. Wait for the water to settle, then throw in a single piece of bread (away from the duck!) and observe how uniformly the ripples spread out in a pure circle.
This is an EXACT analogy of how sound waves travel in air. A single source (one speaker) produces a series of vibrations (ripples) that travel out from the speaker in a coherent (all together) fashion. The result - beautiful clear, direct sound with no confusion. Multiple speakers (2 or more) produce vibrations exactly like the confused ripples you saw when throwing multiple objects into the pond and produce lots of incoherent (confused) vibrations.
This is complicated by the fact that as you change position (even slightly) in front of a multiple speaker, you hear different combinations of ripples (vibrations) that affect your perception of the sound - you lose focus.
Given the pond illustration, a single speaker must have the edge when it comes to producing a focused, coherent sound front and this is true. The difficulty is that no single driver can reproduce the full range of sounds contained within the audio spectrum and we need both a woofer and tweeter to achieve this. The point source problem is solved very cleverly by mounting the tweeter at the center and on the same exact axis as, the woofer. This Dual Concentric approach CAN and DOES produce the same clearly focused pattern as a single speaker, but crucialy, now across the whole audio spectrum. Hence we get the best of both worlds. "
