If I've read it once in mainstream audio magazines, I've read it a hundred times: "The most important component in a system is the loudspeaker, because it is the loudspeaker that makes the sound." Putting aside the obvious illogic of this statementthat without other components in the playback chain, even the perfect loudspeaker can't make a soundmy experience is that it just is not so. Yes, it is true that changing from one loudspeaker to another makes the greatest overt changes in a system's sound.
Most audiophiles are aware of the modification and add-on aftermarket. A few have learned the hard way that modifier competence varies from primitive magic and sales hype to real engineering skill. Some modifiers are serious audiophiles who are also good technicians; others are scam artists whose only goal is to make a quick buck on the latest fad. If you have only a rudimentary understanding of electronics, you may not be able to make a distinction. Even the most jaded and battle-hardened among us can still be hooked and reeled in by a slick sales presentation.
