What are Coaxial Speakers?
Coaxial speakers are speakers which include a woofer with a tweeter suspended over the woofer. The woofer handles low to mid-frequency sound, while the tweeter handles high frequency sound. Coaxial speakers are commonly seen in car audio systems, although they can be used in other locations as well. By contrast, a component speaker system separates the woofers and tweeters, and often includes a subwoofer for really low frequency sound.
As a general rule, component speaker systems are of better quality, although some coaxial speakers can be quite good. People use coaxial speakers because they tend to be less expensive, and because they are easier to install. Instead of dealing with an assortment of component speakers, someone can install two coaxial speakers for stereo sound with a broad range. Coaxial speakers are also easy to balance, because all of the sound comes from the same place, rather than being distributed across an area by a component system.
There are several things which should be considered when evaluating coaxial speakers for purchase. The first is the mounting depth, which will determine how easy or difficult the speakers will be to install. Ideally, the speakers should fit existing speaker mounts, making it very simple to put them in place. If the shape and mounting depth are not compatible with existing mounts, it may be necessary to build mounts or to enlarge the existing ones, which can be problematic.
The frequency response range is also important. The broader range, the more sounds will be transmitted by the speakers. Coaxial speakers with a big range will produce the highs and lows of the sound, creating rich, textured playback. Narrow ranges will leave out lower and higher frequencies, and they can make sound seem flat or lacking in dynamics. The power rating is also a consideration, as the power rating needs to match that of the amplifier to avoid blowout.
In the store, packaging sometimes talks about “2-way” or “3-way” speakers. Two way coaxial speakers are the standard, with the woofer and one tweeter. Three way speakers include an additional tweeter, and other options like four and five way speakers with additional tweeters are also available. Sound quality and depth can be increased with additional tweeters, but a speaker is also only as good as its individual components; a low cost three way coaxial speaker will not sound as good as a high quality two way speaker.
