Koaxialhögtalare

Koaxialhögtalare, also known as coaxial speakers, are a type of loudspeaker design where two or more speaker drivers are mounted concentrically on the same axis. Typically, this involves a woofer and a tweeter, with the tweeter positioned in the center of the woofer cone. This arrangement ensures that sound from both drivers emanates from the same point in space, a concept known as coincident point source.

The primary advantage of this design is improved stereo imaging and a more coherent soundstage. Because the sound waves from both the low and high frequencies originate from the same location, they arrive at the listener's ears simultaneously, reducing phase distortion and phase cancellations that can occur with separate drivers. This leads to a more natural and immersive listening experience.

Koaxialhögtalare are commonly found in car audio systems due to their compact nature and ability to deliver a broad frequency range from a single mounting point. They are also used in some home audio applications, particularly in studio monitors and compact bookshelf speakers. Variations exist, with some designs incorporating additional drivers like mid-range units within the coaxial structure. The crossover network, which directs specific frequency ranges to the appropriate drivers, is a critical component in the performance of a coaxial speaker.
