Today, the common market of the main speaker to speaker and closed vented enclosure-based, today introduces a more complex design speaker - labyrinth speaker.
Speakers also called labyrinth or meander transmission line speaker enclosure, the sound is actually mounted baffle plate within a few speakers, forming a tortuous long burst pipe through sound baffle plate so that the acoustic wave back through speaker speaker long meandering conduit reflected burst, and then spread into the space.
The labyrinth speaker is actually the opposite of the sound wave speaker unit through a long pipe reflected, and the length of the pipeline is designed focal burst labyrinth speakers. Rational design labyrinth speakers, speaker at work, and if the sound waves radiated acoustic wave phase opposite to the front speaker unit, a labyrinth duct playback speaker disincentive should be consistent if the acoustic wave phase front speaker unit, a labyrinth the speaker playback pipeline should play to enhance the role.
Playback can solve the drawbacks of insufficient pipeline listening space, that is, when the sound source is too close to the human ear, the ear is hard to feel the high quality of the bass, while the sound effects create a distortion of the audio frequency down to a minimum.
Even before the introduction of the vented enclosure is characterized by enhanced low frequency acoustic energy. Relative to the labyrinth of a vented loudspeaker advantage over speaker is an acoustic wave burst from the back of the speaker through a long length of the pipe, the pipe burst can enhance the low-frequency limit frequency energy designs, it is easy to dive deeper talk is low, higher bass loudness.
Now you can see on the market labyrinth speakers have made in UK TDL series, the John Wright is the founder of the plant design and development. John Wright believes vented enclosure although improved low-frequency radiation energy to some extent, but not so low dive very deep. For example, to hear low-frequency sounds 20Hz, the length of the room to reach about 17 meters, even if it is at least 1/2 wavelength should be 8 meters, the average family rarely have such a listening environment, and can be achieved with a labyrinth speaker such listening environment.
Disadvantage labyrinth speaker box design is complex, difficult to effectively control the low-frequency characteristics, tightness of the work tank, and other demanding, low smearing readily bad design, is often said low delay high. Almost no domestic plant a few speakers can make a real explosion models labyrinth speaker, but because of the labyrinth speakers can get deeper bass, still favored by those hardcore enthusiasts.
